A 45-piece U.S. Marine Corps Band will fill the streets of Little Italy with music Saturday during a free concert in the heart of the community.

Marine Band San Diego, and its groups, Sound Strike and the New Orleans-style Double Time Brass Band, are set to perform from 6 p.m. to dusk at W. Fir Street, between India Street and Kettner Boulevard, as part of Little Italy’s Summer Concert series.

The evening concert is presented by the Little Italy Association of San Diego and Torrey Pines Bank.

Parking in Little Italy – especially on the weekends – can be a challenge. A couple of paid parking options for this event include:

• India and W. Ivy streets (5:30 p.m. to 11:30 p.m. – presented by Ballast Point Tasting Room & Kitchen)
• Kettner Boulevard and W. Ivy Street (5:30 p.m. to 12 a.m. – presented by Herb & Wood)
• India and W. Cedar streets (6 p.m. to 11 p.m.)
• India and W. Date streets (6 p.m. to 11 p.m.)
• India and W. Fir streets (6 p.m. to 11 p.m.)

Imperial Beach is surrounded by water on three sides.

The National Oceanic and Atmospheric Administration predicts sea levels could rise by up to six and a half feet by 2100, which means drastic increases in erosion, flooding and storms for communities like I.B.

Such a rise in sea levels could eventually impact 30 percent of the city’s property, 40 percent of its roads, an elementary school, the sewer system and more.

If residents want to keep tourism, recreation and protect the environment, they would need to choose strategies that keep their beaches wide and protect them from coastal erosion.

In this week's San Diego Explained, NBC 7 San Diego's Monica Dean and Voice of San Diego's Maya Srikrishnan explain how the coastal city is bracing for sea levels rise.

He isn't a politician, but many are hoping the father of a slain Muslim-American war hero will become one after his powerful Democratic National Convention speech, NBC News reported. 

Democratic activist Tom Keefe, launched a fundraiser called "Yes We Khan" on Crowdpac.com, a nonpartisan site that helps citizens find and support local candidates. The fundraiser, which aims to get Khan in the Virginia House of Delegates, raised more than $11,000 in just 24 hours. Khan's son died in Iraq in 2004.  

Keefe was on stage with other veterans at the DNC and said he was struck by the emotional force of Khan's speech lambasting Republican presidential nominee Donald Trump's call to ban Muslims from entering the U.S.

"I just thought, this guy might be somebody who could really turn things around for us," Keefe, 67, told NBC News.

Dylann Roof, the man charged in the massacre of nine parishioners at a historically black church in Charleston, was assaulted Thursday by another inmate at the South Carolina jail where he is being held, authorities said, NBC News reported.

An inmate exited his cell, ran down the stairs and attacked Roof while he was showering, according to a Charleston County Sheriff's office incident report.

Roof, 22, sustained bruises to his face and back. Dwayne Stafford, 25, will be charged with assault in the third degree, Charleston County Sheriff's Office Spokesman Major Eric Watson told NBC News.

Roof faces the death penalty in upcoming trials in both federal and state courts.

Thousands in Anaheim lost power amid an outage that affected hotels and, briefly, Disneyland Wednesday evening, Anaheim Public Utilities confirmed.

During the outage, firefighters received at least five calls reporting people trapped in elevators at hotels, including the Anaheim Carriage Inn, Anaheim Desert Inn, Best Western and Hyatt. 

Riders also reported getting stuck on Disneyland attractions during the brief outage because park attendees had to reset the rides.

"Everything just went black," said park visitor Jo Beard. "We stuck it out."

The power outage, which also knocked out power to stop lights near the Disneyland park, was affecting areas near Anaheim Boulevard and Katella Avenue, as well as near Harbor Boulevard and Katella Avenue.

Anaheim Public Utilities reported that 4,400 customers were without power, and the Disneyland parks initially experienced the outage before backup generators kicked in.

The outage lasted for about 40 minutes to all other areas surrounding the park. An animal "interacted" with a transformer, causing the outage, Anaheim Public Utilities Melissa Seifen said. 

The Park Vue Inn, about two blocks from the Disneyland Resort, reported that it lost all power around 9 p.m. The Anaheim Marriott, located at 700 Convention Way, also confirmed it lost power.

The Disneyland Hotel was not affected by the outage, a desk worker reported. 

Disney's Suzi Brown confirmed that power dipped during the outage. A majority of rides and attractions were not affected by the loss of power, Brown said. Those affected were being reset.

Park-goers posted photos to social media when the dip at the park occurred. 

Power was slowly restored to several areas at 9:20 p.m.

Disneyland park attendees also voiced frustration about the cancellation of the iconic fireworks show, but Brown said it was canceled due to wind concerns, and had nothing to do with the outage.

A '"UFO" got a police escort last week when it roamed the streets of Ireland, but the rolling saucer wasn't from outer space. It was made right here on Earth.

Ali Kemal Ali, 53, told the Belfast Telegraph he initially completed the craft as part of a visual arts course he was taking. The saucer later became the centerpiece of an Irish art exhibition called Third Space Pop Art Show.

Ali said he wanted more people to see his creation.

"I thought, 'How can I attract a bit more interest?'" he recalled. "I thought, 'I'll go and ask the guards,'" Ali said, referring to the Garda, the Irish civilian police force. "I asked, 'Can they give me a police escort with my UFO?' They loved it." 

The fiberglass flying saucer reportedly runs on two electric scooters and is complete with a strobe light, laser, smoke machine and a loudspeaker designed to reproduce low bass frequencies that sound out of this world.

Video of the craft's journey taken by onlookers shows the saucer even made its way through a neighborhood park.

"How often do you go into a police station and ask for something like this? It's always doom and gloom," Ali added. "They saw the funny side of it."

Ali posted a video of the saucer’s police escort, which now has almost a million views on Facebook.

Tracy Mull found a deal online she couldn’t resist: a 55-inch 4K TV for $600 on Walmart.com. 

When the big box arrived, Tracy and her son installed the TV and it worked fine. Then they woke up the next morning. 

“I turned on the TV and it went to this gray screen and then it flashed,” Tracy says. “Then it wouldn’t power up anymore.” 

Tracy says she called Walmart.com. They were gracious and helpful, she says, sending a second television right away and offering a $60 credit. But, when Tracy programmed the second television, it too had problems that wouldn’t go away. 

This left Tracy with two broken televisions and no easy way to return them. She drove them to her local Walmart store, only to be told that Walmart.com and Walmart stores are managed separately and there was nothing the local store could do to help her with the returns. Tracy left the TVs at her local Walmart store, only to be told she needed to go back, pick up the TVs and ship them to Walmart.com. 

Frustrated, Tracy called NBC 7 Responds. We reached out to Walmart.com about the situation. Shortly after, a representative called Tracy to apologize for the mishap saying she no longer had to pick up the TV’s after all and offered Tracy a full refund for the broken sets. Normally customers would be required to ship the product back to Walmart.com when returning an item, but the company made an exception for Tracy. 

Like Tracy, most people may not know what an online retailer’s return policy is until they’re in the situation of having to return something. 

Before you pull your credit card out to make a purchase, find the online retailer’s return policy and figure out the answers to these questions: 

• How much time do you have to return an item for a full refund vs. store credit?

• Does the original purchase come with a shipping label, in the event of a return? Or will you be on the hook for packaging and postage?

• Is there a separate phone number or way to get ahold of the retailer, in the event of a return?

• Are there any reviews from shoppers who had to return an item? What was their experience?

• If the item you purchased is an article of clothing or footwear, does the retailer have a different set of rules for returning these items?

• Is the item required to have all tags and other branding still attached when you make the return?

Bottom line, always do your research before you make a purchase. 

In the event of needing to return something, don’t delay. Online retailers are often shortening the time periods you have to make that decision on whether or not you want to return the item purchased.

Detectives are investigating a suspicious blaze that gutted the home of a New York suburb's only black firefighter — two days after he received a threatening and racist letter in his mailbox.

Kenneth Walker, 28, his wife Amanda and their two kids were not at their North Tonawanda apartment on Wednesday when the fire broke out, local police said, NBC News reported.

"FBI has received a copy of the note left at Mr. Walker's residence and we were notified of the fire that occurred there," FBI spokeswoman Maureen Dempsey said in a statement.

U.S. Attorney William Hochul Jr. said his office has also joined the investigation.

"The public should know that we take all such incidents extremely seriously," Hochul said in a statement Wednesday.

Police are warning hikers and mountain bikers to be vigilant after someone apparently placed booby traps, including barbed wire and wooden planks with protruding nails, just beneath the surface of trails in a New Jersey park. 

Wayne police say a resident told them he has been finding the traps on the trails at High Mountain Park since June 23. He has found broken bottles behind or next to rocks or logs, rope and barbed wire strung across pathways and wooden planks with screws and nails sticking out of them placed just under the road surface to injure hikers or pop bicycle tires, authorities say. 

Police said the man's report about the traps was the first they'd heard of them; it wasn't clear if anyone had been hurt.

High Mountain Park is shared among the jurisdictions of Wayne, North Haledon and Franklin Lakes, and Wayne police say anyone who has seen any suspicious activity in the park should contact their local department. 

A new wildfire exhibit has opened at the Visitor Center of Mission Trails Regional Park to warn about the dangers of flying embers, according to city officials.

In the middle of a hot, dry summer, city officials are preparing for an already active wildfire season. The educational exhibit shows how strong winds and burning chaparral can create flying embers that are almost invisible and span great distances.

This educational exhibit opened last week, and is viewable daily between 9 a.m. and 5 p.m. at One Father Junipero Trail in San Diego, CA 92119. City officials said this will teach San Diegans how to prevent wildfires that can travel nearly six miles through flying embers.

“Thanks to the hard work of Park volunteers and staff as well as the gracious financial support from Councilmember Chris Cate’s office, the exhibit will provide important educational information about wildfires and the hidden threat of flying embers to San Diego residents for years to come,” said Councilmember Scott Sherman, in a statement.

It’s common for flying embers to enter a home undetected and spark a catastrophic fire that significantly damages property, said city officials. During the fire season in 2007, there were homes catching on fire when the primary source of flames was about an 80-minute drive away.

“Fire season is already proving to be extremely severe in central and northern California,” said Fire-Rescue Chief Brian Fennessy, in a statement. “This exhibit shows it’s not only homes near canyon rims that need to be prepared. All of San Diego must be prepared and do their part to prevent the spread of wildfires.”

City Councilman Scott Sherman also wrote an op-ed for the Times of San Diego on Wednesday about the importance of using exhibits such as this one to educate the public about wildfire safety.

A woman pulling a ticket at a parking structure fell out of her car and became trapped, suffering life-threatening injuries, San Diego police officers said. 

The incident happened at 9:51 a.m. when the 65-year-old woman driving a 2014 Dodge Caravan pulled into a Sharp Rees-Stealy parking lot at 2929 Health Center Drive, police said. 

The woman, who has not been identified, stopped and opened her door to pull a parking ticket, police said. 

In doing so, her foot came off of the brake pedal and the car started to roll forward. 

As the car began to move, the woman fell out and became pinned between the driver's door and two yellow poles, police said. 

She was taken to a local hospital with a life-threatening head injury. 

The incident is under investigation. 

No other information was immediately available.

San Diegans are invited to attend a public meeting regarding a proposed increase to parking rates along the waterfront.

The Port of San Diego is considering increasing rates for public parking along the waterfront that could result in millions of dollars in increased revenue over five years.

Port commissioners want to hear reaction to the proposal to increase meter rates along Shelter Island from $1 an hour to $1.25 an hour and to increase parking enforcement hours to 7 days a week from 8 a.m. to 6 p.m.

Also proposed are additional pay stations at Spanish Landing with rates from $1 to $2.50 an hour, enforced seven days a week from 6 a.m. to 10:30 p.m.

They will also propose adding 54 new smart meters along the North Embarcadero Crescent which will also be enforced seven days a week at a similar rate from 8 a.m. to 10 p.m.

The meeting will be held from 4:30 to 5:30 p.m. at the Port Administration Building Training Room, 3165 Pacific Highway, San Diego, 92101.

There may be no indication that Donald Trump is leaving the presidential race or that there will be any attempt to remove him. But the Republican Party does have rules to deal with a vacancy on the ticket, according to NBC News. 

Rule 9 of the party states the Republican National Committee can fill “all vacancies, which may occur by reason of death, declination, or otherwise" of the candidate.

Under the rule, the RNC can either reconvene the entire convention or convene the committee’s 168 members, consisting of three members from each state and territory to represent the delegates. Those members would represent one-third of delegates awarded in each state and would cast a vote for a presidential candidate.

If the GOP no longer wants Trump as its nominee and he doesn’t drop out, the party could remove him. Lawyers defending the move could point to the “otherwise” portion of Rule 9 about when the RNC can intervene to replace a candidate.

The American woman who was fatally stabbed in an attack in London Wednesday was the wife of a Florida State University professor, school officials and Florida's governor confirmed Thursday.

Darlene Horton, 64, wife of FSU psychology professor Richard Wagner was killed when a Somali-Norwegian teen went on a knife rampage through Russell Square. Five others were injured, including an American, Metropolitan Police said Thursday. 

Wagner and his wife were in London while he taught in the summer session at FSU's London Study Program. The school said classes had ended and students enrolled in the program had left for the summer. The couple planned to return to Tallahassee on Thursday, university officials said. 

"There are no words to express our heartache over this terrible tragedy," FSU President John Thrasher said in a statement. "We are shocked that such senseless violence has touched our own FSU family, and we will do all we can to assist Professor Wagner and his loved ones, as well as his friends and colleagues in the Psychology department, as they mourn."

Florida Gov. Rick Scott also confirmed Horton's death Thursday, tweeting condolences to her family and loved ones.

The 19-year-old suspect, whose name has not been released, was subdue by police and arrested at the scene of the stabbings late Wednesday. He remains in custody, Metropolitan Police said.

UC San Diego scientists have created an electronic temporary tattoo that can accurately measure a user's blood-alcohol level and send those results to a mobile device.

The flexible wearable sensor, crafted by nanoengineers at UC San Diego, consists of two parts: a temporary tattoo and a portable flexible electronic circuit board, connected to the tattoo with a magnet. 

The temporary tattoo sticks to a user's skin and induces sweat; the device electrochemically detects the alcohol level. Then, the circuit board sends the information to a laptop or mobile device using Bluetooth. 

“Lots of accidents on the road are caused by drunk driving. This technology provides an accurate, convenient and quick way to monitor alcohol consumption to help prevent people from driving while intoxicated,” nanoengineering professor Joseph Wang, one of the work's leaders, said in a statement.

The technology can be integrated with a car's alcohol ignition interlocks, scientists say. Friends could use the technology to check on each other before handing over the car keys, Wang said. 

“When you’re out at a party or at a bar, this sensor could send alerts to your phone to let you know how much you’ve been drinking,” Jayoung Kim, a materials science and engineering PhD student in Wang’s group, said in a statement. He was one of the paper’s co-first authors.

The most accurate way to measure a blood-alcohol level is to prick a finger. Breathalyzers are non-invasive, but may give false readings, according to UC San Diego researchers.  

The wearable device accurately monitors alcohol levels in sweat; results come in within 15 minutes, local scientists say. 

“What’s also innovative about this technology is that the wearer doesn’t need to be exercising or sweating already. The user can put on the patch and within a few minutes get a reading that’s well correlated to his or her blood alcohol concentration. Such a device hasn’t been available until now,” electrical engineering professor Patrick Mercier said in a statement.

Running strong for more than three decades, Hillcrest will once again host its CityFest this month, an annual, lively street fair held under the community’s namesake sign.

The free, 32nd annual CityFest will flood the streets surrounding the Hillcrest sign on 5th and University avenues on Aug. 14, from 12 p.m. to 11 p.m.

The celebration – which typically attracts more than 150,000 attendees each year – will feature live music, plus arts, crafts and food vendors spanning more than six blocks.

As always, organizers say hundreds of artisans and crafters from across the country will partake in the party, selling their unique, handmade goods.

There will also be an international food court and, for the 21 and up crowd, a beer garden. Meanwhile, family-friendly attractions include a kid’s zone with carnival rides and games. Four areas dubbed “Artist Alleys” will showcase work from up-and-coming local artists, too.

Live music – presented by Hillcrest venue, The Merrow – will fill the air throughout the day, including performances from The Tighten Ups, Paper Days and The Bad Vibes, to name a few acts.

After the sun goes down, DJ’s will take the spotlight on a stage beneath the famous Hillcrest sign, spinning tunes for the second part of the shindig, known as CityFest Night, which often turns into one big, outdoor dance party.

CityFest began in the summer of 1984 when Hillcrest residents gathered on 5th and University avenues to celebrate the re-lighting of the Hillcrest sign in what later became known as the first-ever CityFest.

Today, proceeds from the annual summertime street fair go towards the upkeep of the Hillcrest sign and other beautification projects in Hillcrest.

Democratic vice presidential candidate Tim Kaine spoke about the racial “scar tissue” in Richmond, Virginia, on Thursday during a speech to the National Urban League Conference, NBC News reported. 

During his speech, Kaine spoke about his early career as a civil rights attorney and his work as a politician. The senator also focused on his call for criminal justice reform and the need to "rebuild the bonds of trust between law enforcement and the communities they serve." 

Kaine is still working to introduce himself to a wider American public unaware of many components of his background, told his audience that when he served as Virginia's governor he did something "no other governor had done." 

The Urban League historically invites all major presidential candidates to speak to their conference but the Donald Trump campaign declined an invitation to join this year, Union League president Marc Morial said.

Drivers using the Balboa Avenue off-ramp from northbound Interstate 5 will be detoured for at least a couple of weekends, while construction crews add a second track to the region’s coastal rail line.

The first closures of the off-ramp are set for Aug. 12-15 and Aug. 19-22. The exit will be closed 7 p.m. Friday until 5 a.m. Monday on those weekends, according to the San Diego Association of Goverments (SANDAG).

After these weekend closures are completed, crews will determine whether further closures will be necessary to finish construction on the coastal rail line. City officials say the second track is intended to add more space for passengers on the freight service and increase overall efficiency.

Drivers traveling on northbound I-5 to Morena Boulevard can avoid the construction area by exiting at Clairemont or Mission Bay drives, said officials.

From there, motorists head eastbound on Clairemont Drive, then turn right on Denver Street, right on Ingulf Street and then right onto Morena Boulevard. This detour will allow drivers to continue traveling north to Balboa Avenue.

Other traffic alerts are also in effect near this construction area, including weeknight traffic controls and lane closures along Balboa and Garnet avenues, from 7 p.m. to 5 a.m. While these lanes are closed, SANDAG will keep one lane of traffic open in each direction along that area.

The construction is part of a region-wide effort to implement double tracks, according to SANDAG. Crews will work to relocate underground water pipes near Balboa and Garnet avenues, just east of the I-5.

Most of the construction occurs at night to avoid disrupting the flow of traffic, said officials. There’s also an app called Waze that may help the public navigate through construction areas. SANDAG and Caltrans are providing real-time information on the closures through this free navigation app for smartphones and tablets.
