Torrential downpours that could trigger dangerous flooding is the main threat for the north-central Gulf Coast as Invest 93L targets Louisiana, according to AccuWeather, which is calling the system of low pressure a "tropical rainstorm."
The next named storm of the 2025 Atlantic hurricane season will be Dexter.
Historically, the fourth named storm of the Atlantic hurricane season arrives Aug. 15. The last two named storms of the season — Barry and Chantal — developed earlier than normal.
Here's the latest advisory from the National Hurricane Center as of 2 p.m. July 17:
Invest 93L moving inland over southeastern Louisiana. See path, impacts
Satellite, surface, and radar data indicate that the broad low pressure area is moving inland over southeastern Louisiana, and that the associated shower and thunderstorm activity remains disorganized and located mainly to the west and southwest of the center.
Little development is expected while the center remains near the coast this afternoon and tonight, and the systemis expected to weaken as it moves farther inland on Friday.Regardless of development, heavy rainfall could produce localized flash flooding over portions of the north-central Gulf Coast through Friday.
Formation chance through 48 hours: low, 10 percent.
Formation chance through 7 days: low, 10 percent.
Spaghetti models for Invest 93L
Special note about spaghetti models: Illustrations include an array of forecast tools and models, and not all are created equal. The hurricane center uses only the top four or five highest performing models to help make its forecasts.
Where will Invest 93L go next? Tornadoes, up to 16 inches of rain possible
"Regardless of development, heavy rainfall could produce localized flash flooding over portions of the north-central Gulf Coast through Friday," the National Hurricane Center said.
"Weak steering breezes will guide the rainstorm westward over southern Louisiana on Thursday (July 17), according to AccuWeather. "At that point, steering breezes may drop off, which could allow the rainstorm to stall and produce downpours over the same area.
"It is also possible that more of a northward or westward drift may continue. The former would allow some heavy rain to spread into more of the Mississippi Delta and lower valley region. The latter could allow downpours to spread westward and possibly reach close to Houston.
"It is possible that a couple of tornadoes and waterspouts develop near the central Gulf coast as the storm moves inland on Thursday," said AccuWeather Lead Hurricane Expert Alex DaSilva.
"A sizable zone where 4-8 inches of rain is forecast to fall extends across much of the southern half of Louisiana and part of southern Mississippi. Within this zone, pockets where 8-12 inches of rain can fall are anticipated with an AccuWeather Local StormMax rainfall of 16 inches."
What is an invest?
Short for investigation, the National Hurricane Center uses the term invest for areas of low pressure it is monitoring for potential development into a tropical depression or storm.
Invests are not tropical depressions or tropical storms. They're usually clusters of showers and thunderstorms, and just because they've been designated as an invest does not guarantee they'll strengthen into a tropical storm or hurricane.
Invests run from 90 to 99, followed by a letter: L for the Atlantic basin and E for those in the eastern Pacific. After 99, it starts over again and the next invest would be 90.
Once something has been designated as an invest, specialized data sets and computer models can begin, including scheduling Hurricane Hunter aircraft missions and running spaghetti models.

When is the Atlantic hurricane season?
The Atlantic hurricane season runs from June 1 through Nov. 30.
Ninety-seven percent of tropical cyclone activity occurs during this time period, NOAA said.
The Atlantic basin includes the northern Atlantic Ocean, Caribbean Sea and Gulf of America, as the Gulf of Mexico is now known in the U.S. per an order from President Trump. NOAA and the National Hurricane Center are now using Gulf of America on its maps and in its advisories.
When is the peak of hurricane season?

Why does NHC say 'tropical cyclone' on its maps instead of hurricane or tropical storm?
Tropical cyclone is the generic term used by the National Weather Service, NOAA and the National Hurricane Center for any tropical system, even if it's in the tropical Atlantic basin.
To be more precise, a tropical cyclone is a "rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation," NOAA sadi.
Once maximum sustained winds reach 74 mph, what it is called is determined by where it originated:
: for storms in the North Atlantic, central North Pacific, and eastern North Pacific.
: for storms in the Northwest Pacific.
: for storms in the South Pacific and Indian Ocean.

Map Shows Heavy Rain as Flash Floods Hit Three States
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The National Weather Service (NWS) has issued flash flood warnings for parts of Iowa, Illinois and Missouri, as thunderstorms in the region bring heavy, rapid rainfall. Why It Matters Flooding is the second deadliest weather hazard nationwide, with most fatalities occurring when vehicles are swept away by rising waters. On July 4, Texas flash floods killed at least 135 with three still missing. As of mid-July, the NWS has issued a record number of flash flood warnings year-to-date, with 3,160 warnings issued through July 16, according to Iowa State University's Iowa Environmental Mesonet tracker. What To Know In a Saturday advisory, the NWS warned that portions of the three states are under flash flood warnings due to expected thunderstorms that will bring heavy rain. As of Saturday morning, "between 2 and 5 inches of rain have fallen," and the "expected rainfall rate is 0.25 to 1 inch in 1 hour." For parts of southeastern Iowa, west central Illinois, and northeastern Missouri flash flooding is already occurring, the NWS warned. Missouri Department of Transportation reported that portions of some roads have been closed due to water on the roadways. NWS warned people to "turn around, don't drown when encountering flooded roads," noting that "most flood deaths occur in vehicles." Nearly half of Iowa is also under extreme heat watch on Saturday, as July continues to bake the area with frequent heat indexes into the triple digits. Heat index values reflect how hot it feels when both temperature and humidity are factored in. What People Are Saying NWS Des Moines wrote in a Friday X, formerly Twitter, post: "Dangerous heat & humidity builds across Iowa through early next week. Maximum heat index values are expected to exceed 100 degrees everywhere, with a few locations potentially exceeding 110F! An Extreme Heat Watch has been issued for western/central Iowa beginning Sunday." AccuWeather meteorologist Alex DaSilva previously told Newsweek: "When the atmosphere is getting warmer as a what it's doing is making summer warmer and the shoulder seasons warmer as well. What's happening is those seasons, especially in the summertime, the [atmosphere's] ability to hold more moisture is going up as well. It doesn't guarantee we will see more rain over a certain area, it rains, it's going to rain heavier." Michael Lowry, hurricane specialist and storm expert, wrote in a July 15 X post: "So far in 2025, more flood warnings have been issued by @NWS than any year on record (since 1986)." AccuWeather chief meteorologist Jon Porter said in a July 21 AccuWeather article: "So far in 2025 across the U.S., there's been a 70% increase in reports of flash flooding when you compare that to the 10-year historic average through mid-July." What Happens Next? Many of the flash flood advisories are until 11:30 a.m. local time.

Summer sizzle: NYC, Boston among cities eyeing record highs this week
Summer sizzle: NYC, Boston among cities eyeing record highs this week Intense heat is set to surge into the Northeast late this week, with temperatures climbing high enough in some areas to challenge daily records, according to AccuWeather meteorologists. The brief burst of heat will be fueled by a piece of a larger heat dome anchored over the Great Plains, which is expected to break off and push eastward heading into the weekend. While average temperatures in late July are typically the highest temperatures of the year, driven by intense sunshine, warmer Atlantic and lake waters and long days-this upcoming event may push the upper bounds of historical norms. But, even with routine temperatures typically very high this time of the year, some locations may set daily record highs from Friday to Saturday in parts of the Northeast. Temperatures began to climb on Thursday with widespread highs well into the 80s to mid-90s for the Northeast. Friday will bring the crest of the heat in New England and in the zone from Upstate and eastern New York to portions of New Jersey and northern and eastern Pennsylvania. "In Hartford, Connecticut, the current record of 98 set in 2001 on Friday may be topped," AccuWeather Senior Meteorologist Chad Merrill said. "The record of 99 set in 2016 in Newark, New Jersey, may be swapped by a triple-digit reading." The high temperature in New York City on Friday is projected to approach the record high of 97 from 1999. Meanwhile, in Boston, the high temperature on Friday could come near the record of 96 set way back in 1882, but is forecast to fall a few degrees short with thunderstorms approaching in the late afternoon. "Showers and heavy thunderstorms follow late in the day on Friday and bring a significant cooldown to the upper 70s on Saturday," Merrill said. "This will be a very similar pattern to last month when Boston hit 102 degrees on June 24 and cooled to the upper 70s for highs two days later," Merrill added. Lower humidity will accompany the cooler air in New England and the upper part of the mid-Atlantic on Saturday and may push southward a bit more on Sunday along the Atlantic coast for a time. The temperature boundary will be a focusing point for at least spotty thunderstorm activity this weekend. The storms will extend from parts of the Ohio Valley and Great Lakes states to the mid-Atlantic coast. With more cloud cover around and the likelihood of some local cooling breezes from thunderstorm activity, temperatures may inch downward just a bit over the mid-Atlantic during the weekend but far from the extent enjoyed by millions from this past Monday to Tuesday. Highs in Washington, D.C., will trend downward from near the century mark on Friday to the mid-90s on Saturday and the low 90s on Sunday to put the mid-Atlantic region's cooling trend in perspective. The core of the heat dome will settle southward in the Eastern states over the weekend and will take up residence in the Southeast from Saturday to Wednesday. During this weekend alone, 175 million people will experience RealFeel Temperatures of 100 degrees or higher in the East. The cooling trend in the mid-Atlantic will likely briefly reverse early next week with highs well into the 90s from Monday to the app? Unlock AccuWeather Alerts™ with Premium+ "Much more sweeping changes will come through the Northeast from Tuesday to Wednesday, depending on location, "Merrill said. "A touch of autumn is expected for a few days during the middle to latter part of next week with lower-than-historical average highs that will linger into the first few days in August." The transition could be marked by drenching downpours and gusty thunderstorms. Those with travel plans are encouraged to keep abreast of the forecast for timing and locations of the most severe activity that could lead to disruptions. "In the wake of the storms next week, nighttime temperatures will drop into the 30s and 40s in the Adirondacks and Green and White Mountains with comfortable 60s for much of the Interstate 95 corridor by the end of next week," Merrill said.

National Hurricane Center now tracking 4 waves in Atlantic, Caribbean, rain from Gulf system
The low-pressure system bringing rain and thunderstorms across Florida the last few days is expected to move out of the Gulf inland over southeastern Texas or western Louisiana going into the weekend, ending any chances for further development, according to the National Hurricane Center's July 25 update. "Today will be the last day of widespread heavy rainfall across the Gulf Coast," said National Weather Service meteorologist Mussie Kebede. "Troughing along the coast has offered a lifting mechanism for storm development/organization over the last few days, but should wind down as an upper ridge in the vicinity strengthens. "1-3 additional inches of rain are anticipated from the Florida panhandle to the central Texas coast by Sunday morning. Fortunately, the threat of flash flooding remains marginal due to the relatively low rain rates, resilient soils and efficient runoff methods," the forecaster said. Elsewhere, the NHC is now tracking four tropical waves moving westward across the Atlantic: one near the Lesser Antilles, one in the open Atlantic, a third off the coast of Africa, and a new one in the Caribbean. It's still hot out there. Heat index values ('real feel" temperatures) are expected to reach 100-107 in different areas around the state, but there are no heat advisories in effect today. However, the unusual heat and humidity the country has suffered through the last week will continue through early next week, Labede said, while building across the Southeast and Mid-South this weekend. ➤ Weather alerts via text: Sign up to get updates about current storms and weather events by location The next named storm of the 2025 Atlantic hurricane season will be Dexter. Historically, the fourth named storm of the Atlantic hurricane season arrives Aug. 15. The last two named storms of the season — Barry and Chantal — developed earlier than normal. Here's the latest tropical advisory from the National Hurricane Center as of 8 a.m. July 25: Where is the low-pressure area? A broad area of low pressure located about 100 miles south of the coast of southwestern Louisiana continues to produce disorganized showers and thunderstorms. This system is moving west-northwestward toward the Texas coast, and it has limited time to develop before it moves inland tonight. Regardless of formation, locally heavy rainfall is likely over portions of the northwestern Gulf coast during the next couple of days. Formation chance through 48 hours: Low, 10% Formation chance through 7 days: Low, 10% What else is happening in the tropics? The National Hurricane Center is tracking four tropical waves. Tropical wave 1: A tropical wave is analyzed over the eastern Atlantic near 20W, from 17N southward moving westward at 10 to 15 kt. Isolated moderate convection is depicted just west of the wave axis. Tropical wave 2: A central Atlantic tropical wave is near 40W, from 18N southward, moving west at 10 to 15 kt. No significant convection is active with this wave. Tropical wave 3: A central Atlantic tropical wave is near 56W, from 18N southward, moving at 20 to 25 kt. Scattered showers and thunderstorms are active from 10N to 14N between 54W and 57W. Tropical wave 4: A Caribbean tropical wave is analyzed near 76W, from 19N southward moving west at 25 kt.
