A large part of South Texas is reeling from life-threatening flooding that began overnight and continued into Friday morning.

More than 3,400 in several counties in South Texas remained without power on Friday afternoon, according to AEP Texas. A flood warning was still in effect for portions of South Texas, including Cameron, Hidalgo and Willacy counties, through early Friday afternoon, according to the National Weather Service.

The Pacific Northwest is staring down a rare spring severe thunderstorm threat and Texas is preparing to see up to half a year’s worth of rain by the weekend as March continues its streak of unusually disruptive weather.
