In New York and New Jersey, flooding impacted some subway lines and other mass transit services, including the No. 1, 2 and 3 lines which was severely disrupted in Manhattan due to flooding. Service has since resumed in both directions with residual delays.

The rain fell in two waves, said Gov. Phil Murphy, with the first knocking communities 'off kilter' and the second 'came in for the kill.'

Flash flood warnings were issued by the National Weather service Monday night as heavy storms rolled into the area. Flood warnings were issued for Morris, Warren, Bergen, Essex, Hunterdon, Hudson, Passaic, Middlesex, Somerset and Union Counties, according to the National Weather Service.

Parts of New York City and Northern New Jersey were inundated on Monday night as widespread thunderstorms moved through.

Thousands across New Jersey lost power Monday, July 14, as severe storms blew through the region, toppling trees and knocking down wires.More than 4,600 customers were in the dark as of 6:45 p.m., utility officials said.

More severe storms are possible Thursday in New Jersey after a tornado warning was issued in Atlantic and Ocean counties on Wednesday night. The National Weather Service said a severe thunderstorm capable of producing a tornado was located northeast of Atlantic City at 11:16 p.

A “tropical-like” air mass could yield heavy showers, thunderstorms and wind gusts Monday across the New York City region, the National Weather Service said.

The intense thunderstorm may have looked and sounded like a tornado, but that's not what happened, according to forecasters who examined the damage.
