Powerful thunderstorms are moving across the tristate New York area Thursday. Strong winds and heavy rain are possible.

A Flash Flood Watch is also in effect for several counties, including all of New York City and Nassau and Suffolk, until 6 a.m. Friday.

"With another round of severe weather and heat occurring throughout the state, I urge New Yorkers to stay tuned to local forecasts, and if severe weather is approaching, keep driving and outdoor activities to a minimum," Gov.
