Extensive street flooding and flooding of creeks and rivers are possible. * ADDITIONAL DETAILS... - Thunderstorms are expected across the watch area tonight into Sunday morning. Very high rainfall rates of 2 inches or greater in a short time are possible, which could lead to flash flooding particularly in urban areas.
