Storm tracker: Heavy rain could produce flash flooding along Gulf Coast
The system, designated as Invest 93L, could see some additional development over the next 12-24 hours, according to the National Hurricane Center, however its current structure suggests its chances of developing into a tropical depression before it reaches the Louisiana coast later Thursday are decreasing.
"Regardless of development, heavy rainfall could produce localized flash flooding over portions of the north-central Gulf Coast through Friday," hurricane center forecasters said in an advisory early Thursday morning.
The National Weather Service office that services the Mobile, Alabama and Pensacola, Florida areas is cautioning residents against heavy rainfall Thursday and especially Friday. Forecasters said most areas across northwest Florida, coastal Alabama and southeast Mississippi will see around 2 to 4 inches of rain, while areas further inland could see 1 to 2 inches.
The NWS said the greatest concern for any flash flooding is along the Interstate 10 corridor.

Meanwhile, the NWS office in Tallahassee is strongly encouraging residents and visitors to stay out of the surf where red flags are flying, as the area could see surf heights of 2 to 4 feet and life-threatening rip currents.
Invest 93L currently has a 30% chance for tropical development over the next seven days and a 30% chance over the next 48 hours.
The next named storm of the 2025 Atlantic hurricane season will be Dexter.

How do hurricanes form?
Hurricanes are born in the tropics, above warm water. Clusters of thunderstorms can develop over the ocean when water temperatures exceed 80 degrees Fahrenheit. If conditions are right, the clusters swirl into a storm known as a tropical wave or tropical depression.
A tropical depression becomes a named tropical storm once its sustained wind speeds reaches 39 miles per hour. When its winds reach 74 mph, the storm officially becomes a hurricane.
Prepare now for hurricanes
Delaying potentially life-saving preparations could mean waiting until it's too late. "Get your disaster supplies while the shelves are still stocked, and get that insurance checkup early, as flood insurance requires a 30-day waiting period," NOAA recommends.
Develop an evacuation plan: If you are at risk from hurricanes, you need an evacuation plan. Now is the time to begin planning where you would go and how you would get there.
Assemble disaster supplies: Whether you're evacuating or sheltering-in-place, you're going to need supplies not just to get through the storm but for the potentially lengthy aftermath, NOAA said.
Get an insurance checkup and document your possessions: Contact your insurance company or agent now and ask for an insurance check-up to make sure you have enough insurance to repair or even replace your home and/or belongings. Remember, home and renters insurance doesn't cover flooding, so you'll need a separate policy for it. Flood insurance is available through your company, agent, or the National Flood Insurance Program. Act now, as flood insurance requires a 30-day waiting period.
Create a family communication plan: NOAA said to take the time now to write down your hurricane plan, and share it with your family. Determine family meeting places, and make sure to include an out-of-town location in case of evacuation.
Strengthen your home: Now is the time to improve your home's ability to withstand hurricane impacts. Trim trees; install storm shutters, accordion shutters, and/or impact glass; seal outside wall openings.

Yellow weather warnings threaten to bring flooding and disruption
Yellow weather warnings remain in place for parts of the UK with thunderstorms threatening to bring flooding and disruption for the remainder of the weekend. The Met Office has issued warnings for heavy rain and isolated thunderstorms in Scotland and south-west England and Wales which may cause flooding on Saturday evening overnight into Sunday. Further yellow warnings have also been issued for thunderstorms across much of the country from 11am on Monday until 9pm. The forecaster said there was a slight chance of power cuts and a loss of other services to some homes and businesses as well as flooding and building damage. It said travel disruption was also likely. Some places could see up to 75mm in just a few hours on Saturday and Sunday as the rain becomes persistent and leads to large build-ups, particularly on south-east-facing areas of high ground. In south-west England, including Cornwall, and south Wales, heavy rain and isolated thunderstorms were set to arrive from Saturday evening, spreading further north and east across Wales early on Sunday morning followed by more heavy showers and thunderstorms. A few locations could see 75mm or more, with a small chance of fast flowing or deep floodwater causing danger to life. On Monday, scattered heavy showers and thunderstorms are expected across the main body of England from the bottom of Scotland to the south-east, especially during the afternoon and early evening. The Met Office said that while many parts will miss the worst conditions, a few places could see up to 50mm of rain within a couple of hours alongside lightning strikes and hail. The Environment Agency has removed 28 flood warnings in the last 24 hours, but eight flood alerts remain, mostly around the Midlands such as Birmingham and Wolverhampton, and London. The Scottish Environment Protection Agency has 16 flood alerts in place. Low pressure will linger into early next week keeping conditions unsettled, but there will be sunny spells alongside the heavy showers. These will ease by Wednesday and temperatures will continue to be warm.

Missing Florida man who wandered away at popular New England tourist destination found dead
A 79-year-old Florida man was found dead Friday morning after going missing from the summit of Mount Washington in New Hampshire, the state Fish and Game Department confirmed in a social media post. Officials said search crews had located the body of William Davis after a difficult three-day operation involving helicopters, drones and dozens of ground personnel atop the popular New England summer tourist destination. "It is a tragic end to a tough search mission and the Fish and Game Department would like to thank all the volunteers and staff who worked tirelessly to bring Davis back to his family," the department said in a Facebook post. Davis, of Jacksonville, Florida, reached the summit by way of the Mount Washington Cog Railway on Wednesday afternoon, the Fish and Game Department said in a news release Thursday. He was last seen near the visitor center around 3:20 p.m., after taking a photo with his wife. Soon after, he separated from her and walked toward the trail area alone. At some point, Davis made brief contact with a state park employee by cellphone. He reported being off-trail and described his surroundings but could not explain his location. His phone died during the call. Search teams were notified shortly after 6 p.m. and began looking for him that evening. Crews initially focused on the western side of the summit. Fish and Game officers, park staff, and volunteers from Androscoggin Valley Search and Rescue used drones and ground teams to search the area into early Thursday morning. Fog and wind slowed progress, and no sign of Davis was found, according to officials. On Friday morning, search teams shifted their focus to the eastern and southern slopes of the mountain. Weather conditions had worsened. Rain, clouds, and high winds moved in. Temperatures hovered in the low 40s, and wind chill readings dropped to near freezing. Mount Washington is known for sudden weather changes, rocky terrain, and limited visibility, even in summer. Wind chills can dip below freezing without warning. Although the summit is accessible by car and train, trails just beyond the visitor center can turn treacherous for anyone unfamiliar with mountain hiking. Dozens of rescues are conducted on the mountain each year. At around 11 a.m. On Friday, AVSAR volunteers found Davis's body about 400 feet off the Lion Head Trail. The location was between the Alpine Garden and Tuckerman Ravine Trails, both of which run through rocky and exposed terrain. Rescue officials said Davis appeared to have suffered a serious fall. A Black Hawk helicopter crew from the New Hampshire Army National Guard was conducting a training mission nearby and was able to assist with the recovery efforts during a short break in the weather, officials said. An autopsy is pending at the state medical examiner. Authorities have not determined how Davis ended up in the remote area where he was found. The New Hampshire Fish and Game Department did not immediately respond to Fox News Digital's request for further comment.

Storm Tracker: National Hurricane Center watching disturbance in Atlantic
A tropical wave is interacting with a broad low pressure area to produce the showers and thunderstorms in the open Atlantic Ocean. The National Hurricane Center is watching some disorganized showers and thunderstorms east of the Caribbean that have slight odds of forming into a tropical cyclone, a July 19 outlook says. A tropical wave is interacting with a broad low pressure area to produce the showers and thunderstorms in the open Atlantic Ocean, more than 900 miles southwest of the Cabo Verde Islands, off of Africa, forecasters said. 'Environmental conditions appear marginally conducive for gradual development of this system during the next few days as it moves westward to north-westward around 10 mph,' the center, part of the National Weather Service, said in an update. By the middle of next week, conditions are expected to become unfavorable for the system to develop, forecasters said. AccuWeather said the pattern is expected to be met with wind shear approaching the Caribbean Sea, which could limit the system from intensifying. The Atlantic hurricane season officially began on June 1 and will last through the end of November. Active hurricane weather typically peaks between mid-August and mid-October.
