Here’s where the storm is now and what to expect.
Latest status of Sage. Snow is now spreading across the inland Northeast and decreasing across the Great Lakes. Rain also spread across New England, particularly along the coast.
Winter weather warnings are in effect for parts of many states. The National Weather Service has issued winter storm warnings, winter storm watches, and winter weather advisories for most of New York (including New York City), as well as central and southern New England and northeastern Pennsylvania.
Timing The Storm:
Tuesday. Snow, sometimes heavy, will fall across much of New England and New York. Rain will mix with snow and then turn to all snow across southern and coastal New England, including Boston. Strong winds are expected, especially in coastal New England, but also across much of the Northeast.
Wednesday. The snow will stop in the afternoon. However, strong north-to-northwest winds may remain in New England and parts of the mid-Atlantic for most of the day before dropping overnight.
Prediction effects
Here is how much snow is expected. The most likely area of ​​heavy snow is from parts of New England into northeastern and central New York state and northeastern Pennsylvania. Snowfall will decrease dramatically as you approach the Interstate 95 corridor from downtown Boston to Providence and Hartford, where the least amount of rain is expected.
Higher elevations will see the most snow, with some areas expecting 1 to 2 feet.
Wind can damage or cause power outages. Tuesday, wind gusts up to 60 mph are likely along the coast and southeastern New England, including Boston. Power outages and at least some tree damage are possible in these areas.
Tuesday through Wednesday, much of the rest of the Northeast could see wind gusts up to 45 mph at times. Those flurries, combined with the weight of heavy, wet snow, could lead to some tree damage and power outages in areas of significant snow accumulation, especially in the Inland Northeast.
Coastal flooding is a concern at high tide. Onshore winds may lead to some coastal flooding along the Eastern Seaboard at low tide.
Minor to localized moderate coastal flooding is expected in most areas.
Coastal flooding will peak early Tuesday morning near Long Island and southern Connecticut. Coastal flooding is possible in eastern New England during high tides Tuesday morning, Tuesday afternoon, and Wednesday morning.
Sage can become a “bomb cyclone”
Sage has the potential to become a bomb cyclone as it strengthens off the Eastern Seaboard by early Wednesday.
That means its central pressure could drop by at least 24 millibars in 24 hours or less, signaling an intense, potentially damaging storm.
Summary of Sage so far
Sage entered the West Coast on March 9-10 and hit California with a strong atmospheric river of moisture.
Heavy rain from the storm combined with melting snow caused serious flooding in low-lying areas as heavy snow piled up in the highest peaks of the Sierra Nevada. Up to 40 inches of snow was recorded in the highest elevations of the southern Sierra Nevada.
Snow and gale-force winds spread across the Northern Plains, upper Midwest, and Great Lakes March 11-12.
On March 11, blizzard conditions resulted in nearly all of North Dakota. Many roads in the state, including Interstate 94, were closed.
The storm dumped 12 to 20 inches of snow in northeastern Minnesota and the Duluth-Superior Twin Harbors area in northwestern Wisconsin.
