A significant Nor'easter!

There isn’t much I can say about this nor’easter that I haven’t covered with considerable detail over the last several days.   

The system started developing Monday and is really starting to come together right now. It will continue to impact our region through the weekend; strong winds will lead to tree damage and isolated power outages.

The region has seen stronger nor’easters, but for the first one this season, this will be quite powerful.

Currently the pressure has dropped down to 998 mb, the storm is going to continue to deepen and looks to peak Saturday afternoon/evening. The nor’easter is going to continue to push north, before looping north and east back toward Long Island and New Jersey. It will continue to wobble around off the coast into Monday. Then it will track north and east

With this crawling off the coast, it will allow the storm to produce a long duration of high wind, coastal flooding and drenching rainfall.

Over the next 36 to 40 hours the big story is going to be the wind and waves as this pushes north then west. We’re going to be going through several high tide cycles so moderate coastal flooding and localized urban flooding is a given.

The worst impacts from all of this look to be Saturday and Sunday with the eastern half of New York State and eastern Pennsylvania, into the Middle Atlantic and New England seeing rain, wind, and coastal impacts. The nor’easter is going to linger into Monday as the storm continues to weaken.  The coastal is going to drift close to southeast New England Monday into Tuesday, before starting to depart the region by next Tuesday.

Rain totals could reach 2-to-4 inches from New Jersey to southern Maine. Higher totals of 3-4+ inches could impact Boston, Cape and offshore islands, Rhode Island Southeast Connecticut and Long Island, New York. Rain totals of 5+ inches are possible especially from central Massachusetts to Cape Cod, Martha’s Vineyard and Nantucket.

 Waves of 10-15 feet are likely for the New Jersey shore today through Saturday.  Then from Friday to Sunday, large waves of 15 to 20 feet are possible from Massachusetts to Maine.

 Even though the biggest impacts will be across southeastern New England down into New Jersey and Delaware today through Sunday, some rain and wind will make it into western New England… northern and central Vermont (including the Champlain Valley), much of New Hampshire, central Maine into eastern New York State during the day on Saturday. Generally, rainfall looks to be around 1-2 inches of rainfall, with gust of 20-40 mph.  rain showers will make it as far west as Central New York into northern Vermont, far northern New Hampshire and northern Maine over the weekend. Rainfall totals look to be 0.25- 1.0 inches with wind gust of 10-20 mph.
