Severe storms dumped about half a year’s rainfall in two days, leading to flash floods across both sides of the border.

Waves of downpours and thunderstorms continue across South Texas, driving a flooding and severe weather risk through late Friday. Some places could see up to a foot of rainfall, while others may face a low-end tornado risk.

Heavy rainfall and significant flooding are headed to Southeast Texas Thursday night, as the National Weather Service issued a flood watch.
