Texas’ governor has issued a disaster declaration for six counties hit by severe weather and flooding this week.

Gov. Greg Abbott’s Thursday declaration includes three counties in far South Texas: Cameron, Hidalgo and Willacy counties. It also includes three in the Corpus Christi area: Aransas, Nueces and San Patricio counties.

Both areas experienced flooding this week after being inundated with rains.

The U.S. Border Patrol’s Rio Grande Valley Special Operations Detachment unit rescued nearly 300 people since the flooding started. 

Abbott said in a news release that even before the declaration, he’d authorized the use of all available resources of state government and of political subdivisions to aid in response efforts.
