With blizzard conditions and snow approaching 6 to 12 inches, Suffolk County residents are being advised to stock up on food and water and stay in their homes Wednesday. Strong and gusty winds are also expected during the storm, which will hit just after midnight and last into the night, according to a storm warning issued by the National Weather Service. Gusts of up to 25 to 35 mph are possible. Winds of that speed would cause blowing and drifting snow, making travel hazardous, officials said.
