New York Governor Kathy Hochul declared a state of emergency on Friday for all five boroughs of New York City, along with Long Island, and the Mid-Hudson region of the state.

Flash flood warnings are in order for all of the affected areas through Friday, and New Yorkers are being encouraged to avoid walking or driving through these areas.

As of 3 p.m., over six inches of rain was recorded in Brooklyn, the borough that early reports show may have been the hardest hit by the storm.

"This is a dangerous weather condition and it is not over," Mayor Eric Adams said early Friday morning during a press briefing. "I don't want those gaps in heavy rain to give the appearance that it is over, it is not."

A full travel advisory for NYC is intact through 6 a.m. Saturday.
