The Southwest will see another round of storms on Wednesday as rains associated with former Tropical Storm Javier in Mexico head north. Heavy rain is expected for a second day in Tucson. The National Weather Service has issued a flash flood watch until Thursday. The storm on Tuesday made streets look like rivers. Water swallowed vehicles, including that of a local leader who was rescued through the back window of her county-issued car after it became wedged against a bridge underwater. The Tucson Fire Department says it performed eight water rescues and helped about 45 stranded motorists during a two-hour period of intense rain on Tuesday.
