Weather Alert Issued For NYC As City Expects High Winds and Heavy Rain

The New York City Emergency Management Department (NYCEM) today issued a weather alert ahead of high winds, heavy rain, and thunderstorms tomorrow, Wednesday, December 11. The National Weather Service (NWS) has also issued a citywide Wind Advisory in effect from 12 p.m. to 10 p.m. tomorrow.

Drizzle turns into steady light rain overnight tonight with periods of moderate showers and embedded thunderstorms tomorrow morning. Little to no impact is expected during this time, including during the morning commute.

A period of heavy downpours and potential severe storms is then expected between noon and 6 p.m. tomorrow. Heavy rain during this time may cause minor flooding of low-lying and poor drainage areas, and may temporarily disrupt the evening commute. In addition, there’s a low chance for severe thunderstorms to produce sudden, localized damaging wind gusts, which may result in downed trees and power outages. A few lingering showers will be possible through midnight Thursday, but the heaviest of the rain is expected to end before 6 p.m. Citywide rainfall totals of around 2 inches are expected with locally higher amounts possible.

Outside of thunderstorms, winds increase citywide out of the south tomorrow morning, reaching gusts of up to 55 mph in the afternoon, highest along the coast. Winds will peak between 1 p.m. and 6 p.m. tomorrow, which may cause scattered down tree limbs, localized power outages, and hazardous driving for high profile vehicles. Poorly secured outdoor objects may also be damaged or blown away.

Minor coastal flooding will also be possible during high tides tomorrow in Jamaica Bay, where a Coastal Flood Statement is in effect from 4 a.m. to 7 p.m. for above-ground inundation of up to one-half foot along vulnerable shorelines. Finally, temperatures will drop about 30 degrees from Wednesday afternoon to Thursday evening, with periods of wind chills in the teens through Saturday morning. Icy conditions are not expected as the strong winds tomorrow will help dry out surfaces before temperatures drop below freezing.
