The prospects of blizzard-like conditions slamming Long Island Friday just got even likelier.
The National Weather Service Thursday afternoon issued a blizzard warning for all of Long Island beginning 6 a.m. Friday until 1 p.m. Saturday.
The weather service also upped its predictions of snow accumulation in both Nassau and Suffolk Counties, noting that both could see more than one foot of snow.
Meteorologists predicted Nassau could get blanketed with 10 to 14 inches, while Suffolk could be hit with 10 to 15 inches.
The powerful winter storm is expected to also bring winds of 20 to 40 mph, plus gusts of up to 60 mph.
On top of the heavy snow predictions, the national weather service is also calling for temperatures Friday night to fall into the 20s.
The strongest winds and heaviest snowfall will occur Friday evening into Saturday morning, the NWS said.
The potential blizzard also makes driving dangerous, with the storm possibly spawning whiteout conditions. The weather service warned residents not to drive, but if people must travel “have a survival kit with you.”
The NWS also issued a coastal flood warning for both counties, noting that waves could reach up to 13 feet in Suffolk.
Widespread flooding of vulnerable shore roads and basements is also expected, meteorologists said, adding, “numerous road closures may be needed.”
National Grid, which will be leading storm response over the Long Island Power Authority, said Thursday that the storm could knock out power to more than 100,000 customers.
