SOMERSET COUNTY, NJ - A line of intense thunderstorms is expected to move into the region from the northwest late Tuesday afternoon and evening, according to the National Weather Service. There are indications that storms may repeatedly move over the same areas, especially during the evening hours, they said. Localized rainfall of one to three inches is likely where this occurs, and combined with the rainfall received this past weekend, this may lead to instances of flash flooding.
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. Monitor the forecast, especially if you live in a location that is prone to flooding.
The areas of greatest risk are poor-drainage and urban locations, where rapid runoff may cause localized flash flooding. Quickly responding creeks and streams may also experience flooding in areas receiving the heaviest rainfall. The storms are expected to move through the area during or just after the evening commute. Motorists should be prepared for torrential downpours and potential flooding as the storms move through.
