New Orleans could get 10 inches of rain from tropical system
New Orleans and Jefferson Parish officials are preparing for up to 10 inches of rain as a tropical system heads toward Louisiana. Why it matters: That's more rain than New Orleans typically gets in the entire month of July. Some parishes are preparing for the threat by setting up sandbag locations and encouraging residents to prepare for the possibility of street flooding. The big picture: The system was moving over Florida on Tuesday and expected to reach the Gulf on Wednesday, the National Hurricane Center said. A tropical depression could form while it moves west in the Gulf, per NHC. It will be named Dexter if it strengthens into a tropical storm. It's expected to approach Louisiana's coast on Thursday, NHC said. Between the lines: It's the Gulf Coast's first storm threat of the 2025 hurricane season. The biggest concern for southeast Louisiana is flooding, according to the National Weather Service's Slidell office. It's too early to tell where the heaviest rain will fall. The latest: Multiple rounds of heavy rainfall are expected to start Wednesday in New Orleans and continue through at least Saturday morning, NWS said. It's "not out of the question" for some places to get more than 10 inches, NWS wrote in its Tuesday forecast. New Orleans is most likely to get 3 to 4 inches by Sunday, with higher totals on the coast, per NWS. Rainfall rates in some storms could be more than 4 inches per hour, which is faster than the pumps can drain streets. A flood watch is in effect for southeast Louisiana and south Mississippi from Wednesday through Saturday morning. What to do now: Leaders are asking residents and businesses to clear catch basins in front of their properties now. Clean your gutters, too. It's also a good time to check your emergency kit and charge your phone and electronics in case there's an outage. Make sure you have a way to get info (Ex. NOLA Ready texts or a weather radio). Sandbag sites are open in St. Tammany and Terrebonne parishes, WDSU says. Once the rain arrives, stay off the roads if there's flooding. It's dangerous for you and can push water into homes and businesses. Drainage prep Zoom out: Drainage pumps in New Orleans and Jefferson Parish can handle 1 inch of rain the first hour and 0.5 inch per hour after that when the systems are working at full capacity. When rain falls too quickly, it overwhelms the pumps, causing street flooding. The Sewerage & Water Board said 86 of 93 major pumps (map) were working as of Tuesday. Two of its power turbines were down and available only for emergency use. SWBNO crews are drawing down canals and cleaning catch basins in anticipation of the rain, spokesperson Ceara Labat tells Axios New Orleans. All the underpass pumps were working, SWBNO said, with the exception of one of the three that drain the Carrolton Avenue/I-10 underpass. In Jefferson Parish, all 194 pumps were working as of Tuesday, per drainage director Ben Lepine. Employees have also tested all the generators and were ready to staff pumping stations 24 hours a day if needed, he said in a statement. Public works employees are focusing on cleaning catch basins until the rain arrives. Entergy said it is monitoring the storm and preparing for severe weather in south Louisiana. The company has materials, supplies and staffing available if needed, a spokesperson tells Axios New Orleans. What we're watching: Meteorologists are monitoring where the system goes once it enters the Gulf, which will give them a better idea where the heaviest rain will fall.

Tropical Storm Dexter: Live Tracker as Chances of Forming Quadruple
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. Chances that Tropical Storm Dexter will form within the next 48 hours have quadrupled since a forecast issued by the National Hurricane Center (NHC) on Monday. As the storm takes shape, Florida can expect heavy rainfall. Even if the storm doesn't form, the heavy rain will move across the Sunshine State and into the Gulf, where it will impact coastal states later this week. As of Tuesday around noon Eastern time, AccuWeather Lead Hurricane Expert Alex DaSilva told Newsweek the storm was moving inland and bringing "really, really heavy rain." Why It Matters The Atlantic hurricane season began on June 1. The last storm to form was Tropical Storm Chantal earlier this month. NHC meteorologists are currently monitoring a low-pressure system east of Florida that has a 40 percent chance of becoming tropical within the next 48 hours. Should it form, the storm will be named Dexter. The development comes as meteorologists predicted an above-average hurricane season this year for the Atlantic. A map from the NHC shows there is a 40 percent chance Tropical Storm Dexter will form within 48 hours. A map from the NHC shows there is a 40 percent chance Tropical Storm Dexter will form within 48 hours. National Hurricane Center What To Know On Monday, the NHC said there was a 10 percent chance the storm would form within the next two days. By that afternoon, the chance had increased to 20 percent. By Tuesday morning, the chances increased again to 40 percent. The NHC cautioned that even if it doesn't form, Florida can expect some impact, such as heavy rain and flash floods. Weather Radar Animated weather maps from showed a cluster of storms in Florida near the state's Atlantic coast. As of Tuesday afternoon, the storms have not yet organized into a tropical system. DaSilva told Newsweek he doubts the storm will strengthen while it moves over land. Wind Despite the lack of organization, some strong winds are still expected with the storms. Sustained winds of around 25 mph were recorded in the Atlantic Ocean to the east of Florida. Winds were gusting around 36 mph. A tropical storm has sustained winds between 39 and 73 mph. A tropical storm becomes a Category 1 hurricane once sustained winds hit 74 mph. Rain Meteorologists warned that the biggest impact from the storm will be heavy rain. Over the next three days, forecasts that Central Florida could receive around 2 inches of rain. The highest rainfall amounts will be coastal Louisiana, which could receive up to 4 inches. What People Are Saying The NHC, in a forecast: "This system is forecast to move westward across the Florida Peninsula today and then reach the northeastern Gulf by Wednesday. Environmental conditions appear generally favorable for additional development, and a tropical depression could form while the system moves across the northeastern and north-central Gulf." AccuWeather Lead Hurricane Expert Alex DaSilva, in an AccuWeather report: "Heavy downpours are expected to continue across much of the Florida Peninsula through Tuesday night. Thunderstorms, infused with tropical moisture, could produce more than 4 inches of rain." What Happens Next Heavy rain is expected to cause flash flooding in Florida through mid-week, the NHC forecast said. Then, flash flooding and heavy rain will hit the Gulf Coast later this week.

Tropical Storm Dexter Update: Spaghetti Models Show Potential Florida Path
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. Forecast models show possible paths for a disturbance near Florida that could develop into Tropical Storm Dexter this week. Why It Matters The Atlantic Hurricane season has seen three named systems: Andrea, Barry and Chantal. Chantal brought heavy rain and flooding to North Carolina this month, with up to nine inches of rain falling within 24 hours in some parts of the state. The first spaghetti plots are out for 93L for what would be Tropical Storm Dexter. Landfall could happen as early as 72 hours from now. The faster track would allow less time for rapid intensification. The faster the better in this scenario. I will begin live tropical updates… — Reed Timmer, PhD (@ReedTimmerUSA) July 15, 2025 What To Know Spaghetti models shared on social media suggested a westward trajectory across Florida, then a shift northward into the Gulf states, with the system potentially reaching as far north as Tennessee and Kentucky. According to the National Hurricane Center (NHC), recent satellite-based wind data suggested that the low-pressure system just off Florida's east coast is gradually becoming more organized. However, its associated showers and thunderstorms remain disorganized. "This system is forecast to move westward across the Florida Peninsula today and tonight, then reach the northeastern Gulf by the middle part of this week," the NHC said in an update Tuesday morning. "Environmental conditions appear generally favorable for additional development, and a tropical depression could form by the middle to latter part of this week as the system moves across the northeastern and north-central Gulf." This NHC map highlights the area in question. This NHC map highlights the area in question. National Hurricane Center The NHC said that regardless of development, the system could bring heavy rainfall and flash-flooding to Florida and parts of the north-central Gulf Coast this week. The agency reported a 40 percent, or "medium," chance of cyclone formation within the next seven days, with the same likelihood projected for the next 48 hours. AccuWeather meteorologist Dan Pydynowski told Newsweek that AccuWeather was concerned about the potential for tropical development possibly as early as Tuesday or Wednesday after the system crosses the Florida peninsula and moves westward. "We then expect the system to approach the central Gulf Coast later this week, perhaps sometime on Thursday, as a tropical depression or potentially a tropical storm. The exact wind intensity would depend on its exact track across the [Gulf of America, GOA], if it stays out over the open waters of the central GOA or if it hugs the coast. If it hugs the coast, that could limit its potential to intensify due to interaction with land." What People Are Saying Meteorologist Matt Devitt said on X, Monday: "While in the Gulf, track is key for what this becomes or doesn't become. For example, if it rides more north along the Gulf Coast, it would spend less time over water and would be not even developing. If it heads more south, it would spend more time over warm water and become landfall also more west from Alabama to Louisiana. To what intensity? Too early to tell, let's see what the system looks like after it leaves Florida." AccuWeather meteorologist Dan Pydynowski told Newsweek: "In terms of expected rainfall, there could be a wide swath of rainfall of 4-8 inches across central Florida over the next few days. This heavy rainfall can lead to localized flash flooding. As it moves into Louisiana later this week, heavy rain will spread inland across the northern Gulf Coast. A wide swath of 1-2 inches could extend from far eastern Texas through the Florida Panhandle. Along the central Gulf Coast in southern MS and southeast LA, 4-8 inches of rain will fall." What Happens Next Meteorologists will keep tracking the system and share new information as it evolves. The Atlantic hurricane season runs from June through November. The Eastern Pacific hurricane season began on May 15 and lasts until November 30.

Odds increase for tropical storm forming off the Florida coast
The odds of a major rainstorm turning into a cyclone off the Florida coast have just quadrupled, hurricane forecasters warned Tuesday. The National Hurricane Center (NHC) updated its outlook for the system, raising the chances of cyclone formation from 10 percent to 40 percent in the next 48 hours. The weather service added that potentially devastating storm surges of up to three feet could be seen in New Orleans by Wednesday night. 'Regardless of classification, the storm will bring heavy rainfall and flash flooding to Louisiana and the central Gulf Coast,' the AccuWeather team wrote in an urgent alert Tuesday morning.

National Hurricane Center has a warning for Florida, Texas as Gulf tropical development chances are increasing
The National Hurricane Center is closely monitoring a cluster of thunderstorms, designated Invest 93L, off Florida's east coast, with increasing chances of tropical development. Central Florida is bracing for heavy rainfall, potentially reaching up to 3 inches in some areas. Regardless of tropical development, high rain chances persist through the week, with potential localized flooding. 93-L will move into the Gulf on Wednesday where it will continue to act like a water hose, pumping a lot of moisture toward Central Florida so rain chances remain high Tired of too many ads? Remove Ads Will Florida get rainfall? Tired of too many ads? Remove Ads The National Hurricane Center is keeping a close eye on a cluster of thunderstorms off the coast of Florida or possible tropical development later this week. The chances of development of a tropical depression or tropical storm off Florida's east coast are increasing, the NHC said, as the system is becoming better NHC is calling this " Invest 93L ", a term used to identify systems that could develop, allowing more sophisticated, high-resolution computer models to be run on them. Invest 93-L is looking better organized Tuesday morning and will move over Central Florida throughout the day and it is likely to bring several bouts of rain and storms up to 3 inches of rain in some areas.93-L will move into the Gulf on Wednesday where it will continue to act like a water hose, pumping a lot of moisture toward Central Florida so rain chances remain high for us through late week regardless of any tropical development, as per media reports. If a tropical storm does develop, it would be named a high-pressure system over the northeastern Gulf drifts slowly westward on July 15, it will provide an opening for the elongated low-pressure area in the Atlantic Ocean to "mosey westward," said the National Weather Service in disturbance may encounter more favourable conditions and strengthen into a potential tropical cyclone later in the week once it moves off Florida's west coast and along the northern Gulf coast, Jeffrey Lewitski, one of the center's lead forecasters was quoted as saying by USA Today. The center has upped the chances of the system becoming a tropical depression or storm to 30% by Wednesday and 40% through Sunday."Some areas will receive multiple rounds of rain for the next couple of days which can lead to localized flooding," said the weather service office in the Ruskin/Tampa if something tropical develops or not, the forecast for Florida will remain the same for the most numerous showers and thunderstorms across the state the next few days. This will be an uptick in showers and storms compared to the 'normal' summertime pattern of pop-up afternoon storms, according to Weather Channel. The chances of rain will go up for the Panhandle and the entire Gulf Coast by mid to late week as the low continues to move toward the west-northwest. This low will increase instability in the area, which will bump the rain chances heavy downpours could lead to flash flooding in some spots near the Gulf Coast later in the week. And some remnant moisture and spin could keep that locally heavy rain threat in the lower Mississippi Valley into next National Weather Service is urging residents and visitors, anywhere from Florida to Texas, to stay up to date with the forecast and follow any guidance issued in regard to any tropical development.
