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 fourfold 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."

"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
AccuWeather Lead Hurricane Expert Alex DaSilva told Newsweek: "We continue to monitor the tropical rainstorm that is approaching Louisiana this morning. Right now it's a little hard to locate the center of the rainstorm but it looks like it is just southwest of Mobile, Alabama.
"There is still a very slight chance that this rainstorm could gain a bit of organization before landfall later today. If this occurs, it could become a short-lived tropical depression. Regardless of classification, it looks like heavy rain will be the primary concern by far across Louisiana."
DaSilva said in an advisory shared with Newsweek earlier 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."
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.
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.
