Tropical Storm Alberto made landfall in northeastern Mexico Thursday morning, but it has since weakened to a tropical depression as the storm heads west, the NHC said at 10 a.m. local time.

At least three people died in the storm in Mexico, multiple outlets reported—a man who drowned in a river located in Monterrey city and two minors died in the Allende municipality after riding a bicycle in the rain, according to the Associated Press, citing local media.

Southern Texas experienced heavy rainfall and flooding Wednesday, though it is expected to subside for the remainder of Thursday, according to the NHC, while northeastern Mexico could see another 5 to 10 inches of rain and some Mexican states—Coahuila, Nuevo Leon and Tamaulipas—could see maximum rainfall of 20 inches.

Texas Gov. Greg Abbott issued a severe weather disaster declaration for 50 counties Wednesday, including Galveston, Jackson and Uvalde counties.
