Late-Season Snowstorm: When, Where And How Much

HUDSON VALLEY, NY — Yes, it's April 18 and there are winter storm warnings in effect for parts of the Hudson Valley.

The mid-Hudson region, including the Catskills, could see up to a foot of heavy, wet snow.

According to the expected snowfall map issued Monday afternoon by the National Weather Service, Sundown, a hamlet in Ulster County could see more than 8 inches of snow and Hunter in Greene County is forecast to have almost 10.5 inches.

Gov. Kathy Hochul has directed state agencies to prepare emergency response assets in advance of the late-season winter storm.

"As New Yorkers, we know all to well that winter can last beyond March," she said, "and this week we're preparing for a storm expected to bring up to a foot of snow in some parts of the state, making for a messy commute on Tuesday."

A winter storm warning is in effect from 6 p.m. Monday to noon Tuesday for western Greene and western Ulster counties. It calls for total snow accumulations of 5 to 10 inches.

Sullivan County's winter storm warning is for the same time period but is predicting 4 to 9 inches of snow.

And the areas where it's not going to snow have rain to look forward to. Possibly lots of it.

For Rockland and Westchester counties, there is a flood watch in effect from 10 p.m. Monday to Tuesday morning.

Southern Westchester, additionally, has a wind advisory in effect (20 to 30 mph winds with up to 50 mph gusts) and a coastal flood warning.

The National Weather Service said coastal flooding could happen from midnight Monday to 4 a.m. Tuesday, with 1 to 2 feet of inundation above ground level in vulnerable areas near the waterfront and shoreline.

So here's an idea of when the messy weather with start and when it will end.
