Flash Flood Watch
NWS also issued a flash flood watch, which will be in effect from 10 p.m. Aug. 3 until midnight Aug. 5.
According to NWS, heavy rain associated with Tropical Storm Isaias is expected to start as early as late Monday evening and will continue through the day Tuesday. Widespread amounts of 4 to 6 inches are forecast with locally higher totals possible.
A flash flood watch means that there is the potential for flash flooding which can be life-threatening. Heavy rain is expected to occur over a short period of time. Rapidly rising flood waters may quickly inundate roadways and areas of poor drainage. Streams and creeks could leave their banks, flooding nearby properties.
Please monitor the forecast, especially if you live in a location that is prone to flooding. Be prepared to take action if a flash flood warning is issued for your area.
