MAINE, USA — The second nor'easter of the month is on its way to Maine this week. It's what we call a "Miller B" storm that comes off the coast of the Carolinas and "phases" with upper-level energy from the Great Lakes.
This is a storm that will have plenty of time to dump heavy snow on the region. Think of it like a car that gets a flat tire on the weather highway (the jetstream) and "stalls" in the southern Gulf of Maine.
Light rain along the southern coast Tuesday morning will change to snow Tuesday afternoon as the storm begins to rapidly strengthen near Cape Cod and into the Gulf of Maine.
It will be a "bomb cyclone," meaning it undergoes bombogenesis by falling in pressure at least 24 MB in 24 hours. The wind will be out of the northeast, making it a "nor'easter."
This storm will be a minor to moderate nor'easter for much of the Pine Tree State according to the Winter Storm Severity Index.
Interior York County could see major impacts from heavy, wet snow and wind gusts that could lead to power outages.
Here's a look at the updated impacts from the storm, beginning during the day on Tuesday:
Wind gusts out of the northeast will combine with the heavy, wet snow, setting up the potential for widespread power outages.
High seas will cause minor coastal flooding from Portland south to the seacoast.
By the time the storm exits to our east, here's what you can expect for snow totals:
The 10"+ possible jackpot zone is for interior York County heading up into part of western Cumberland and southern Oxford Counties.
