High waters are flooding neighborhoods around Houston following heavy rains that have already resulted in crews rescuing more than 300 people from homes, rooftops and roads engulfed in murky water. Still others prepared to evacuate their properties. The Houston area was under threat of worsening flood conditions Saturday, a day after heavy storms slammed the region and authorities warned those in low-lying areas to evacuate ahead of an expected “catastrophic” surge of water. A flood watch remained in effect through Sunday afternoon as forecasters predicted additional rainfall Saturday night, bringing another 1 to 3 inches of water to the soaked region and the likelihood of major flooding.
