Storm Coordination Message #1 – Monday Afternoon 11/30/20 Through Tuesday Morning 12/1/20 Storm Potential
Hello to all…
..Powerful storm system will bring heavy rainfall, strong to damaging winds, the possibility for Isolated Strong to Severe Thunderstorms and possibly some minor coastal splashover to minor coastal flooding to Southeast New England Monday Afternoon through early Tuesday Morning..
..A High Wind Watch is now in effect for Monday Afternoon and Evening for Eastern Essex, Eastern Norfolk, Bristol, Plymouth Counties, Cape Cod and the Islands and all of Rhode Island except Northwest Rhode Island for sustained winds of 20-30 MPH with gusts to 60 MPH and isolated higher gusts possible. Much of the rest of Southern New England could see wind gusts as high as 50 MPH with isolated higher wind gusts. These winds will cause isolated to scattered pockets of tree and power line damage and power outages. The timeframe of strongest winds is from 2 PM Monday through 1 AM Tuesday..
..The Storm Prediction Center (SPC) has placed Connecticut, Rhode Island and Southeast Massachusetts in a marginal risk for severe weather for Monday with damaging winds brought to the surface in any thunderstorms as the main threat..
..Rainfall of 1-3″ with isolated higher amounts could cause urban and poor drainage flooding. Strong winds may cause minor splashover to minor coastal flooding in Southeast New England..
..SKYWARN Self-Activation will monitor the storm for rainfall reports, rainfall and coastal related flooding and measured wind gust and wind damage reports..
A powerful storm system will track west of Southern New England putting the region in the strong to damaging wind, heavy rain side of the storm with even the potential for strong to severe thunderstorms in Southeast New England. The headlines depict the latest thinking. Key factors include:
1.) The strength of the low level winds and the ability of the strong winds to reach the surface in either heavy rainfall or thunderstorms to cause higher wind gusts.
2.) Heaviest and higher end rainfall amounts and how widespread they are based on thunderstorm development or how widespread the heavy rain swath is.
SKYWARN Self-Activation will monitor the storm for rainfall reports, rainfall and coastal related flooding and measured wind gust and wind damage reports. Another coordination message will be posted by 1030 PM Sunday evening.
