Slow-moving storms with heavy rain were drenching a large swath of South Texas on Wednesday, a day after downpours washed out roads and farmland and led to dozens of high-water rescues.
Warnings of potentially dangerous flash flooding were posted in some areas as the deluge was expected to continue through Thursday evening. The National Weather Service said 10 to 20 inches (25 to 50 centimeters) of rain was possible in some areas by the time the storms move out.
