HOUSTON (AP) — High waters flooded neighborhoods around Houston on Saturday following heavy rains that resulted in crews rescuing more than 400 people from homes, rooftops and roads engulfed in murky water. Others prepared to evacuate their properties.

A flood watch remained in effect through Sunday afternoon as forecasters predicted additional rainfall Saturday night and the likelihood of major flooding in Harris County, the nation’s third-largest county which includes Houston, and nearby areas.

“A lull in heavy rain is expected through (Saturday) evening,” the National Weather Service reported. “The next round of heavy rainfall is expected late (Saturday) into Sunday.”
