Treacherous flood threats linger over Gulf Coast with potential tropical storm brewing over region
The risk of dangerous flooding continues along the Gulf Coast from a no-name storm system that could lead to days of an enhanced flood risk along and north of the Interstate 10 corridor. The system, identified as Invest 93L, originally developed east of Florida before traversing the entire state and ending up over Louisiana and Mississippi. Advertisement Due to its proximity to land and hostile upper-level winds over the Gulf, the disturbance never reached tropical depression or tropical storm status, despite producing conditions similar to a tropical cyclone – impacts that are expected to continue through the early weekend. Forecast models show communities between New Orleans and the Texas-Louisiana border could see an additional 2–4 inches of rainfall, with locally heavier amounts. In the stronger cells, an isolated waterspout or tornado is not out of the question, but the threat will remain concentrated over the southern parishes in Louisiana. Due to the rainfall threat, Flood Watches remain in effect along the I-10 corridor, as some rainfall rates could approach 1–2 inches per hour, which is enough to overwhelm drainage systems.

FOX Weather Forecasters remind residents that just 6 inches of moving water can knock an adult off their feet, while a foot of floodwater can cause a vehicle to stall and float away. Flood Watches have also been issued for parts of the Tennessee and Ohio valleys, where some of the moisture could stream northward towards, but the predominant feature responsible for that precipitation is a stalled frontal boundary. 3 A rain squall passes over the wetlands in southern Louisiana on August 30, 2021, in Houma, Louisiana.

Just because what has been known as 93L has moved inland, its future remains murky and may, in fact, find itself over open waters in roughly a week. Forecast models show the moisture and circulation within the disturbance meandering over the Southeast because of a building ridge over the northern U.S., essentially blocking its exit. This could send the disturbance back over the southwest Atlantic and northern Gulf – the same waters where it originated for a second chance of organization. Advertisement The National Hurricane Center has not highlighted the region yet for development, and the chances remain low that a cyclone will form either in the medium or long-term future, but it is a possibility that the FOX Forecast Center will be monitoring. A classic example of a circulation leaving the Gulf only to return as a cyclone is Hurricane Ivan back in 2004, but that system was a powerful hurricane – not a weak disturbance that struggled to even reach tropical depression status. A return to the Gulf would likely only result in heavy rainfall and rough surf – similar to the first go-around, but the forecast will continue to be fine-tuned during the upcoming days.

Tropical Storm Dexter Update as Chances of Cyclone Changes
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 chances of invest 93L—a disturbance over the Gulf Coast with the potential to become Tropical Storm Dexter—developing into a cyclone have fallen, according to the National Hurricane Center (NHC). Why It Matters The Atlantic Hurricane season has seen three named systems so far in 2025: Andrea, Barry and Chantal. Chantal brought heavy rain and flooding to North Carolina earlier this month. What To Know As of early Wednesday, the NHC was giving the system a "medium," 40 percent chance of cyclone development. This was a four-fold increase from Monday, when chances were reported at 10 percent. But in an update on Thursday morning, the NHC had downgraded chances to 30 percent, or "low." This NHC map highlights the area in question. This NHC map highlights the area in question. National Hurricane Center "Recent satellite wind data, in combination with surface and radar observations, indicate the broad area of low pressure located over the far northern portion of the Gulf remains quite disorganized," the agency said. "In addition, the associated shower and thunderstorm activity remains displaced well west of the broad center." "While some additional development of this system remains possible over the next 12-24 hours, its current structure suggests its chances of developing into a tropical depression before it reaches the Louisiana coast later today are decreasing." However, the NHC added that regardless of whether the system develops further, it could bring heavy rainfall and localized flash-flooding to parts of the north-central Gulf Coast through Friday. The agency gave a 30 percent chance of cyclone formation within the next seven days, with the same likelihood projected for the next 48 hours. What People Are Saying Meteorologist Dylan Federico said on X, on Wednesday: "Invest #93L looks like a plate of scrambled eggs this morning on satellite. I thought it made a run at depression status yesterday, but this thing is a mess and has a long way to go before being named #Dexter. AccuWeather Lead Hurricane Expert Alex DaSilva said, in an advisory shared with Newsweek on Wednesday: "Flash flooding is a major concern through the end of the week into the weekend as this tropical rainstorm moves across the Gulf coast and inches closer to Louisiana. "Do not wait for this tropical rainstorm to strengthen to a named tropical storm before taking action. We expect serious flooding issues regardless, even if does not get an official name designation." What Happens Next Forecasts are subject to change, and meteorologists will continue to monitor the system. The Atlantic hurricane season runs from June through November, while the Eastern Pacific hurricane season began on May 15 and lasts until November 30.
