A Major Storm which has caused significant disruptions to the Mid-Atlantic
region including the Washington DC and Philadelphia area is taking aim on
Southern New England. There has been some changes since the last forecast,
those changes are as follows:
1.) More mixing of Sleet possible into the Boston-Providence Corridor but
this will not hold snowfall amounts much in this area with 12″ or more of
snow still expected.
2.) South Coastal Rhode Island, South Coastal Massachusetts and Cape Cod
will see a changeover to rain but not until 10-12″ of snow falls in the
area.
3.) Martha’s Vineyard and Nantucket will see 4-8″ of snow before a
changeover to rain.
4.) Higher Amounts of snowfall are now forecasted across Western, Central
and Northeast Massachusetts and Southern New Hampshire.
The following is a breakdown of snowfall by geographic area:
Southeast Middlesex County: 15-25″ of snow
Southern New Hamphire: 16-24″ of snow
Eastern Essex, Norfolk, Plymouth, Northern Bristol, Suffolk Counties
Massachusetts including the Boston Area:
12-20″ of snow. Mix to Sleet and Freezing Rain possible before a change back
to Snow.
Eastern Kent and Southeast Providence Counties of Rhode Island:
12-20″ of snow. Mix to Sleet and Freezing Rain possible before a change back
to Snow.
Western and Central Massachusetts from Worcester County West, All of
Northern CT, Northern Providence County RI:
12-20″ of snow from Willimantic, CT to Woonsocket, RI.
15-25″ of snow for Western and Central Massachusetts and the hilly terrain
of Northern CT.
South Coastal Massachusetts and Cape Cod: 10-12″ before a changeover to
Sleet, Freezing Rain and then Rain.
Martha’s Vineyard and Nantucket: 4-8″ before a changeover to sleet and
rain between 3-6 PM.
Snow has already begun along South Coastal Massachusetts and South Coastal
Rhode Island, the snow will gradually make its way through the region
falling at a light-moderare rate before heavier bands of snow up to 2-3″ per
hour begin to take hold over the region. Snow is already falling moderate in
intensity in places like Hartford, CT and across much of the New York City
area and South Coastal CT. 8″ of snow has already fallen in the New York
City Area. The progression will be slowly and steadily northeast into
Northeast Massachusetts and Southern New Hampshire. With the strong winds
expected over the area, a period of whiteout or near blizzard conditions are
possible. At this time, the storm intensity is being held just below
Blizzard threshold and this needs to be monitored closely for any possible
upgrade.
Coastal Flood Threat:
The threat of coastal flooding will be most significant on the Midday
Tuesday High Tide Cycle, however, we will need reports of how the high tide
cycle for Monday Night develops as this could be a precursor for
difficulties in the high tide cycle for Midday Tuesday. It is also likely
that there will be minor coastal flooding at the time of high tide tonight
followed by a threat for moderate coastal flooding for midday Tuesday.
Wind Threat:
A Wind Advisory has been posted for portions of Eastern Massachusetts and
South Coastal Rhode Island. This means sustained winds of 31 MPH or greater
with wind gusts of 46-57 MPH possible. These winds coupled with snow could
knock down trees and power lines and cause possible power outages. These
winds could produce a period of near Blizzard conditions over parts of the
area where snow is still falling late this afternoon through Monday Morning.
SKYWARN Activation Status:
SKYWARN Activation will begin with Ops at NWS Taunton between 11 AM-1 PM and
continue through at least 11 PM tonight or Midnight Tuesday. A break in Ops
may occur at Midnight with Ops restarted Tuesday Morning through Midday to
cover heavy snowfall and strong winds in New Hampshire along with coastal
flooding at the time of the Tuesday Midday high tide.
ARES/RACES Activation Status:
Please consult with your ARES or RACES leaders on possible activation in
areas hardest hit by this major nor’easter.
This will be the last email posted on this situation. Pages will be sent
throughout the day to update this significant threat.
