The first Nor’easter of the season is still developing down south, but will pack a wallop to the Northeast this weekend.
Portions of the deep South and Tennessee have been getting drenched today as a low pressure system glides along the Gulf coast. This rain will move into the Carolinas and the Ohio River Valley tonight and Friday, followed by the mid-Atlantic by Friday evening.
This system has combined with the remnants of Hurricane Willa which hit western Mexico earlier this week, then moved across Mexico into the United States. There will be plenty of moisture in the storm as it barrels toward the Northeast and gets stronger.
Here’s what to expect based on the latest computer forecast models and outlooks from the National Weather Service.
Washington, D.C., Baltimore, Philadelphia, Atlantic City, Delaware, New York City, Long Island, Hartford, Providence, and Boston:
Wind gusts of 40 to 60 mph causing some power outages, knocking down power poles and trees
Torrential rain blowing sideways, up to 2 inches of accumulation
Some coastal flooding and high surf
Portions of upstate New York, Maine, New Hampshire, and Vermont:
Periods of snow, rain, sleet, and freezing rain
Slushy snow accumulations of up to 4 inches
Some icy roads
Winds not a major issue
Rain and strong winds will likely begin Friday evening in the mid-Atlantic, then spread northward into New England Friday night. It’ll go all day Saturday, finally losing some steam Saturday night into Sunday as it moves toward the Maritime Provinces of Canada.
Prepare for delays/cancellations if you’re booked on a flight into or from cities in this region. Also, moving freight will be challenging, especially on major routes such as the I-95 corridor. Because of the winds, this will be especially true for anyone driving empty vans.
Contrary to popular belief, a Nor’easter isn’t just a snowstorm or blizzard. According to the definition from the National Oceanographic and Atmospheric Administration (NOAA), a Nor’easter can produce heavy rain and/or snow. They usually develop between Georgia and New Jersey, within 100 miles east or west of the East Coast. These storms move northeastward and typically reach maximum intensity near New England and the Maritime Provinces of Canada. They also produce winds of gale force (39-54 mph), rough seas, and sometimes coastal flooding. Nor’easters can occur at any time of year but are most frequent and most violent between September and April.
