The first tropical storm of the season, Arthur, formed off Texas Wednesday morning, and it could dump “life threatening” amounts of rain along the Gulf Coast.

While conditions aren’t favorable for Arthur to become a truly powerful storm in terms of wind speed, it’s still expected to bring a dangerous amount of rain to several states.

Estimates have ticked up since Tuesday. Up to 20 inches of rain in some spots are is predicted, with 5 to 10 inches of heavy precipitation across swaths of Texas, Louisiana, Mississippi, Alabama, Georgia and even the far western reached of the Florida Panhandle.

The system will likely fade within a day or so, forecasters said.

Parts of the Gulf Coast could see five to 10 inches of rain this week from the tropical system hovering offshore of Texas.
