While the barrage of deadly thunderstorms that hit Texas this week has tapered off, various cities aren't out of danger, as officials warn about possible flooding from rivers swollen by rainfall.
In suburban Houston, subdivisions along the San Jacinto River were expected to flood.
In Wharton, located southwest of Houston, residents in 300 homes on the west side of the city were asked to evacuate due to the predicted rise of the Colorado River. And in the North Texas town of Horseshoe Bend, about 250 residents were asked to evacuate, as the Brazos River was expected to rise above its flood stage.
The death toll from the storms and flooding has climbed to 21 — 17 in Texas and four in Oklahoma. Houston alone had six storm-related deaths.
