According to the Associated Press, another death was reported in the Mexican state of Tamaulipas, located near the U.S.-Mexico border — bringing the death toll up to at least four. The extreme rainfall also pummeled parts of northeastern Mexico, with the region seeing between 7 and 12 inches of rain, according to AP.

At least three people died in southern Texas and one across the border in Mexico after as much as 20 inches of rain fell in parts of the Rio Grande Valley, stranding motorists and causing widespread destruction.

Flooding in the Rio Grande Valley has left at least four people dead, forcing water rescues in several counties and causing widespread power outages and school closures.
