Another round of thunderstorms moved across the New York metropolitan area Thursday afternoon and evening. However, the more severe storms remained south of New York City and mainly affected New Jersey, according to the National Weather Service.

Heavy rain could result in flash flooding. The NWS expected total rain amounts to range from 1 to 2 inches in central and southern New Jersey and about 1 inch in northeast New Jersey, with locally higher amounts possible.

"Flash flooding is possible in places where the heaviest thunderstorms persist. Rises on rivers and streams with urban, small stream, and poor drainage flooding is also possible," the NWS said. "For areas that experienced flooding on Wednesday, it will not take much additional rainfall for those areas to experience flooding once again this afternoon and evening."

The National Weather Service issued a Flash Flood Warning through Thursday evening for the following counties:

NEW JERSEY

  • Morris
  • Somerset

The Flash Flood Watch issued for much of New Jersey has expired.

What does a Flash Flood Watch mean?

"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," the NWS said. "Streams and creeks could leave their banks, flooding nearby properties."

An EF1 tornado touched down in New Jersey on Tuesday evening. The rating EF1 means the twister had wind speeds of 86 mph to 110 mph.
