warning
Late Monday morning into early Monday evening, the combination of drying fine fuels, southwest wind gusts between 25 and 30 mph, and relative humidity values between 25 and 35 percent will contribute to an elevated risk of fire spread for the Lower Hudson Valley, New York City and northern and western portions of Long Island. This forecast considers meteorological, fuel, and land conditions and has been developed in coordination with state fire and land management officials. As a reminder, the annual statewide burn ban remains in effect until May 14. No burn permits are issued. Use extra caution if handling any potential ignition sources such as machinery or matches and ensure to properly extinguish or dispose of cigarette butts. Please refer to the New York State Department of Environmental Conservation website for more information on burn restrictions.
