Okay, so you were woken up by the insanely loud clap of thunder and pelting rain at 2 a.m. Monday—that was one thunderstorm. Now, get ready for round two as the New York City region enters yet another flash flood watch.

With showers and thunderstorms expected this afternoon into the evening, the National Weather Service warns that there may be flash flooding, with one to three inches, possibly up to four inches, of rainfall. According to PIX 11, the severe weather is “because of a slow-moving warm front coupled with a lot of moisture in the air.”

The NWS adds, “An isolated tornado cannot be completely ruled out.”

The flash flood watch is from 2 p.m. Monday until 10 a.m. Tuesday. Rain might pour down at one to two inches per hour, which means there may potentially be more flooded subway stations.
