Storm tracker: Hurricane forecasters warn of rainy tropical system along Gulf Coast
The system, which is now a broad area of low pressure, is located along the coast of the Florida Panhandle near Panama City and is producing disorganized showers and thunderstorm activity mainly south of its center, the National Hurricane Center said Wednesday afternoon, July 16.
Hurricane center forecasters said the system, designated as Invest 93L, is forecast to continue moving westward and could emerge or redevelop over the far northeastern to north-central portion of the Gulf, reaching the coast of Louisiana by Thursday.
Tropical depression could still form
"If this system moves far enough offshore, environmental conditions over the Gulf appear generally favorable for additional development, and a tropical depression could still form over the next couple of days before the system moves fully inland by the end of the week," the hurricane center said in its 2 p.m. ET advisory on July 16.
The system is expected to provide heavy rainfall, which could produce localized flash flooding over portions of Florida through Wednesday. Flash flooding could also occur in portions of the north-central Gulf Coast beginning late Wednesday and continuing through Friday, the hurricane center said.
The National Weather Service in New Orleans warned that the system will bring locally heavy rainfall capable of causing flooding to southeast Louisiana and coastal Mississippi, especially on Thursday and Friday.
Overall, the weather service said that up to 10 inches of rain could fall in portions of southern Louisiana over the next several days.
AccuWeather forecasters expect a potential tropical depression to make landfall in southeastern Louisiana Thursday afternoon, bringing heavy rain and storm surge. Storm surge of 1 to 3 feet and wind gusts from 40 to 60 mph are possible in southeastern Louisiana to coastal Mississippi, according to AccuWeather, especially if the storm organizes into a tropical storm before landfall.
Invest 93L currently has a 40% chance for tropical development over the next seven days and a 40% 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.

Heat maps show half the U.S. under advisories, warnings
About half the country is under active heat advisories on Monday, affecting more than 198 million Americans, according to the National Weather Service. The extreme heat is expected in the Midwest, the Southeast and some parts of the Northeast. The heat alerts will remain in effect through Wednesday night in some places. Many areas have already been experiencing heat waves. Tampa, Florida, usually cooled down by a sea breeze, hit a record high of 100 degrees on Sunday, local media reported. Temperatures on Monday are forecast to be in the high 90s for multiple cities with feels-like temperatures over 100 degrees. Health-related illnesses can increase significantly during extreme heat. It's advised to drink plenty of water and stay in air-conditioned rooms, meteorologists said. Some northern Midwest states also face severe storm threats on Monday. A derecho, an intense line of fast-moving thunderstorms, is expected early in the evening over parts of eastern South Dakota, the NWS said. It's then expected to move into parts of southern Minnesota and northern Iowa. "Several wind gusts in excess of 75 mph, a few line-embedded tornadoes and instances of severe hail are also probable, according to the Storm Prediction Center," the NWS said.

Extreme heat safety tips as dangerous temperatures hit US
More than 185 million Americans are on alert for life-threatening heat and humidity from South Dakota to Florida on Monday. Parts of Mississippi and Louisiana are on alert for heat indices -- what the temperature feels like with humidity -- of up to 120 degrees. Extreme heat warnings are in place for parts of South Dakota, Nebraska, Iowa and Illinois, where it could feel like over 110 degrees. MORE: How to conserve energy during a heat wave From Boston to Philadelphia, it'll feel like the mid-90s to lower 100s through Wednesday. Extreme heat is considered the deadliest weather-related hazard in the U.S., according to the Fifth National Climate Assessment. About 2,000 Americans die each year on average from extreme heat, according to the Centers for Disease Control and Prevention. Here are heat safety tips from the CDC: Wear sunscreen Take precautions to prevent sunburn, which can make you dehydrated and affect your ability to cool down. Use sunscreen that's SPF 15 or higher 30 minutes before going outside. Sunscreens that say "broad spectrum" or "UVA/UVB protection" are best. Stay hydrated Drink extra fluids, and don't wait until you're thirsty. Avoid very sugary drinks and alcohol, which can cause your body to lose more fluid, and be wary of extra-cold drinks that may cause stomach cramps. Avoiding hot and heavy meals also can reduce your body's overall temperature. Limit time outside Cut down on exercise during heat waves and rest often and in shady areas. Try to limit your time outside to when it is cooler, like in the early morning and evening. Check the car Never leave children in a parked car -- even if windows are cracked open. MORE: Hot car safety tips Monitor high-risk loved ones Anyone can suffer from heat-related illness at any time, but these people are at greater risk: -- Babies and young children -- Overweight people -- Those 65 years old or older -- People who overexert during work or exercise -- Those who suffer from heart disease or high blood pressure and those who take certain medications, including for depression, insomnia or poor circulation Watch for signs of illness Symptoms of heat stroke include: -- Body temperature of 103 degrees or higher -- Hot, red, dry or damp skin -- Fast, strong pulse -- Headache -- Dizziness -- Nausea -- Confusion -- Passing out -- No longer sweating Symptoms of heat exhaustion include: -- Heavy sweating -- Cold, pale, clammy skin -- Fast, weak pulse -- Nausea or vomiting -- Muscle cramps -- Feeling tired or weak -- Headache -- Passing out If someone shows symptoms of heat stroke or heat exhaustion, call 911, move them somewhere cooler and use towels to cool down their body. Don't forget about your furry friends! Here are some tips from the American Society for the Prevention of Cruelty to Animals for how to keep your pets safe in the heat: provide plenty of fresh water so they don't get dehydrated; don't over-exercise pets; never leave pets alone in a parked car; and watch for symptoms of overheating, which include excessive panting, difficulty breathing, increased heart and respiratory rate and drooling. Animals with flat faces, like pugs, can't pant as well and are more at risk of heat stroke. These pets, as well as older and overweight pets, should be kept inside as much as possible. What constitutes a heat wave? A heat wave is a continuous period of abnormally hot weather, generally lasting over two days, according to the National Weather Service. However, the definition of a heat wave varies by region. In the Midwest and the Northeast, a heat wave is considered three or more days in a row of temperatures of at least 90 degrees. But in Phoenix, for example, temperatures are regularly well above 90 degrees and into the triple digits without it being from a heat wave. So a heat wave is relative to the local average temperature and may require temperatures to be significantly above normal for several days, according to the NWS.

NWS: Indianapolis temperatures could feel as high as 107 degrees as week begins
A heat advisory is in effect for Indianapolis until 8 p.m. on July 29. Heat indices will spike as high as 107 degrees on Monday and Tuesday afternoons. Overnight temperatures will provide little relief from the sweltering daytime heat, dipping only into the mid-70s. "That's even almost just as dangerous as the hot temperatures, especially for those vulnerable populations without adequate AC," said National Weather Service meteorologist Cody Moore. Moore suggested limiting time outside, wearing light-colored clothing and using a cooling center during the day if needed. "This is above average for this time of year, but we expect this. It's July, this is not anything out of the ordinary," Moore said. Humidity increases in part at this time of year because of the phenomenon of "corn sweat," he added. Isolated thunderstorms will provide some temporary relief amidst the sweltering weather on July 28 and July 29. But as the sun comes back out in the afternoons, the residual moisture from those storms will make the air feel very humid. A flood warning is in effect for Marion County until 11:15 a.m. on July 28. The heat wave should break on July 30, when a storm system will move into the area and knock temperatures down to more tolerable levels for at least a few days. On July 31, the high temperature will be a modest 78 degrees. Indianapolis weather forecast ☀️/⛈️ Monday: Showers and thunderstorms likely, mainly before noon.

Stay hydrated. Drink plenty of water. Check on relatives and neighbors, especially the elderly and those without access to air conditioning. Avoid strenuous outdoor activities. If possible, delay outdoor chores until the evening hours. When working outside, wear light, loose-fitting clothing. Take frequent breaks in the shade or an air-conditioned room. Know the signs and symptoms of heat exhaustion or heat stroke. If you or someone you know experiences signs of heat stroke, call 911 and take immediate action to cool off the person until help arrives. Never leave children or pets unattended in a vehicle. Bring pets indoors and ensure they have plenty of water to drink. The city said pets are not to be outside unsupervised when the temperature is higher than 90 degrees or a heat advisory is in effect. Consider carrying an umbrella for immediate shade while outside. Dial 211 or 866-211-9966 to reach Indiana 211 for non-emergency resources.
