State of Emergency declared as blizzard targets NYC area

Gov. Kathy Hochul on Saturday declared a State of Emergency in more than 20 counties and activated the New York National Guard ahead of a powerful blizzard expected to impact New York City, Long Island and the Hudson Valley.

Officials warn the storm could bring dangerous travel conditions, coastal flooding and widespread power outages.

Beginning Sunday, 100 National Guard members and 25 vehicles will be staged across downstate regions to assist with storm response. The State Emergency Operations Center will also activate Sunday morning. Winter Storm Warnings are in effect for parts of the Hudson Valley, where 10 to 15 inches of snow and wind gusts up to 45 mph are possible. Additional counties are under Winter Storm Watches.

Transit agencies are adjusting service, and beginning at 4 p.m. Sunday, empty commercial vehicles and tandem tractor trailers will be banned from I-84 and roads south of it, including sections of the Thruway. Hochul urged residents to prepare now, avoid unnecessary travel and monitor weather updates.

Blizzard conditions expected Sunday night into Monday

Forecasters say the storm will strengthen quickly offshore, producing snowfall rates of 1–2 inches per hour and wind gusts of 50 to 55 mph. AccuWeather warns that heavy snow combined with strong winds could create blizzard conditions across Long Island, New York City, and coastal areas.

“The storm will be incredibly disruptive and dangerous,” said Carl Erickson, AccuWeather director of forecasting operations. “Blowing snow and near-zero visibility will make travel nearly impossible during the worst of the storm.”

The strongest winds are expected Sunday night into early Monday.
