Due to periods of heavy to excessive rain expected today through Friday, the National Weather Service has extended a Flash Flood Watch through Friday evening.
The Watch is set to expire at 10:00pm Friday.
According to the NW, several rounds of showers and thunderstorms are expected this afternoon and evening, and again Friday, especially during the afternoon and evening. Many of these storms will produce heavy rain. If some of these storms repeatedly cross the same locations, it could cause flash flooding.
Flood prone roads adjacent to streams could be eroded and washed out by high, fast-moving water. If you encounter water over the roads turn around and seek and alternate route. It especially difficult at night to discern the depth of water over a road, and even if that road may be washed out.
