What could become the first tropical storm of the Atlantic hurricane season is supercharging flooding in Texas and parts of the Gulf Coast this week.

Tropical Storm Arthur, the first named storm of the 2026 Atlantic hurricane season, formed Wednesday off the Gulf Coast of Texas before later weakening to a post-tropical cyclone.

Tropical Storm Arthur made landfall in Texas Wednesday afternoon but coastal flooding and rough surf continue.

Arthur, the first named storm of the 2026 Atlantic hurricane season, has weakened to a post-tropical cyclone, but it will continue fueling a deadly flood threat across the Gulf Coast and into the South through Friday.

Tropical Storm Arthur formed near the Texas coast and is expected to bring life-threatening flooding across portions of the Southeastern U.S., the U.S. National Hurricane Center said on Wednesday.

A cold front could bring a new wave of storms to North Texas this week. (Ali Majdfar/) Parts of Texas may be getting a reprieve from recent rains and flood waters, but that may only be the calm before the storm returns later in the week.

Looking ahead to Thursday, a First Alert Weather Day is in place due to extreme heat, with a heat advisory in effect at noon.

A tropical storm watch has been issued for portions of the Texas and Louisiana coasts for a system that could soon become a short-lived tropical storm.
