Storm Coordination Message #1 – Thursday Night 3/18/21-Friday Morning 3/19/21 Coastal Storm Potential
Hello to all…
..Coastal Storm system responsible for the severe weather in the Gulf Coast and Southeast United States will bring rain changing to snow across much of Southern New England with light snowfall accumulations expected with a low probability of low-end moderate snowfall amounts in portions of interior Southern New England along with strong to damaging winds in Southeast Coastal New England Thursday Night into Friday Morning..
..A High Wind Warning is now in effect for Nantucket from 2 AM-11 AM Friday for sustained winds of 30-40 MPH with wind gusts to 60 MPH expected. A Wind Advisory is in effect for Eastern Plymouth County Massachusetts, Cape Cod, Marthas Vineyard and Block Island RI for sustained winds of 25-35 MPH with gusts to 55 MPH expected and isolated higher wind gusts possible. Other parts of East and South Coastal Massachusetts and RI could see wind gusts around or over 40 MPH. These winds will cause isolated to scattered pockets of tree and wire damage and power outages..
..Snowfall across much of the region will be 1-3″ in the interior mostly on grassy surfaces with isolated higher amounts possible. Roads could become slush covered. If higher amounts occur in a more widespread area occur of greater than 3″, than isolated to scattered pockets of tree and wire damage and power outages would be possible but at this time amounts are expected to be below this range. This will be monitored closely as it will depend on how heavy the precipitation and timing of the changeover from rain to snow..
..SKYWARN Self-Activation will monitor this storm system for late Thursday Night into Friday Morning. Amateur Radio Call-Up Nets could be utilized Friday Morning for snow accumulation information as well as strong wind gust/wind damage information at the coast.
