NYC region under flood watch as severe storm system tracks east

A slow-moving storm system tracking from the Midwest is headed straight for the New York, New Jersey, and Connecticut regions. FOX 5's Mike Woods warn of a potential "one-two punch" of severe weather, with heavy rain rates of 1 to 2.5 inches per hour expected during the afternoon and evening commute.

  • Morning conditions: Early showers are crossing over from Pennsylvania into Sussex, Warren, and Hunterdon counties. Rain will remain light to moderate early on, with a brief window of relatively quiet weather during the mid-to-late morning hours.
  • Late-morning transition (10 to 11 a.m.): Storm development risks begin to rise rapidly, starting southwest of the region and spreading northeast over the Tri-State area.
  • Afternoon and evening commute: The most impactful weather hits during the afternoon and evening commute. Heavy downpours, strong to severe thunderstorms, damaging wind gusts, localized hail, and isolated tornadoes are all possible.
  • Wednesday: Severe weather risks drop back down to a marginal risk tier across the board, making today the primary event.

The primary threat includes damaging wind gusts of 60 to 70 mph capable of downing trees and power lines, along with large hail up to 1 inch in diameter.
