Widespread Two to Three Inches of Rain or More Expected for Hudson Valley, New York City and Long Island Overnight Thursday Through Friday Evening

Locally Higher Rainfall Amounts of Five Inches or More Could Cause Isolated Flash Flooding; Flood Watch In Effect From 2 A.M. Friday Through Late Friday Evening for all of New York City, Long Island and Hudson Valley

New Yorkers Urged to Stay Aware of Current Weather Forecast, Prepare Households and Vehicles for Heavy Rain Impacts, Use Extra Caution When Traveling Especially Near Flooded Roadways and Infrastructure

Governor Kathy Hochul today urged New Yorkers to prepare for heavy rainfall and potential flash flooding beginning overnight Thursday and continuing through Friday night in the Hudson Valley, New York City, and Long Island regions. The current forecast predicts a widespread two to three inches of rain and locally heavy rainfall of five inches or more is possible, with rainfall rates reaching one inch per hour. These conditions may cause flash flooding in low-lying, flood-prone areas and areas that recently experienced heavy rainfall. In the event of flash flooding, commutes would be impacted on Friday. Governor Hochul urged New Yorkers to pay close attention to the forecast and changing conditions, and her administration stands ready to respond to extreme weather impacts in affected areas.

“With a chance of heavy rain tonight and tomorrow across New York City, Long Island, and the Hudson Valley, we’re keeping a close eye on potential flash flooding,” Governor Hochul said. “I’m directing state agencies to prepare response assets and be ready to assist our partners at the local level if they need support. I encourage anyone expected to receive heavy rainfall over the next 48 hours to stay vigilant, keep a close eye on the forecast, and heed any emergency orders from officials if necessary.”

The National Weather Services has issued a Flood Watch that is set to go into effect overnight Thursday into late Friday evening for parts of the New York City, Long Island and Hudson Valley regions. For a complete listing of weather alerts and forecasts, visit the National Weather Service website at New Yorkers are encouraged to sign up for NY Alert, the State’s free emergency alert system, at County-by-county emergency information can be pushed by text or email.

New York State Division of Homeland Security and Emergency Services Commissioner Jackie Bray said, “New York City, Long Island, and the lower Hudson Valley will see significant rain tonight into Friday night. Parts of these regions may see five or more inches of rain which could lead to flash flooding. My staff is communicating with weather experts and our emergency management partners about the impacts from this storm. We are prepared to respond and assist our local partners to keep New Yorkers safe in the event of a flash flood emergency.”

The best way to receive timely weather alerts is by signing up for NY-Alert, a free service that provides weather and other emergency-related alerts.

Take the following steps to ensure you and your loved ones are protected:

  • Develop a household disaster plan and know how to always contact family members. Identify an out-of-town friend or family member to be the “emergency family contact” and make certain all family members have the contact info.
  • Designate an emergency meeting spot – a familiar location where family can meet if the residence cannot be accessed.
  • Know hurricane and storm risks in your community.
  • If you live near coastal areas, learn about your area’s storm surge history and your community’s warning signals and evacuation plans, including safe routes inland and the location of official shelters.

  • Take the following preventative measures:

– Obtain and store materials, such as plywood, necessary to properly secure your home.

– Repair loose and clear clogged rain gutters and down spouts.

– Secure or bring inside lawn furniture and other loose, lightweight objects such as garbage cans and garden tools that could become projectiles in high winds. Also keep trees and shrubbery trimmed of dead wood.

– Review insurance policies to determine extent of coverage before a storm strikes.
