Storm Coordination Message #2 – Friday Night 3/6/20-Saturday Morning 3/7/20 High Wind/Light Snow Ocean Storm Potential
Hello to all…
..Powerful Ocean Storm has trended a bit further west and bringing the potential for even stronger damaging winds for Cape Cod and the Islands and strong wind gusts further up the Eastern Massachusetts coastline and also bringing an increase in snow accumulations for Cape Cod and the Islands..
..A High Wind Warning is now in effect from 9 PM Friday Evening through Noon Saturday for Cape Cod and the Islands for sustained winds of 30-40 MPH with gusts to 65 MPH and isolated to scattered higher wind gusts. These winds coupled with any wet snow accumulation particularly around or over 3″ will cause scattered pockets of tree and wire damage and scattered power outages..
..A Wind Advisory is now in effect from 9 PM Friday Evening through Noon Saturday for Eastern Essex, Eastern and Southern Plymouth Counties of Massachusetts and Block Island RI for sustained winds of 20-30 MPH with gusts to 50-55 MPH. Other parts of Eastern and South Coastal Massachusetts will see wind gusts in the 40-45 MPH range. These winds will cause isolated pockets of tree and wire damage and isolated power outages..
..A Winter Weather Advisory is now in effect from 8 PM Friday Evening until 11 AM Saturday Morning for Cape Cod and the Islands for 2-4″ of snow with isolated higher amounts up to 6″ on the Outer Cape and Nantucket depending on the track of the ocean storm. Wind gusts 60 MPH or higher may cause a period of whiteout conditions if it snows heavy enough with the strong winds over the area..
..A Coastal Flood Advisory is now in effect from 6 AM-11 AM Saturday Morning for Cape Cod and the Islands and Eastern Plymouth County Massachusetts for minor coastal flooding on the most vulnerable shore roads at the time of high tide Saturday Morning..
..SKYWARN Self-Activation will monitor storm impacts over Cape Cod and the Islands and East Coastal Massachusetts overnight through midday Saturday. In particular, we will monitor the Cape and Islands Weather Net Saturday Morning at 6 AM and monitor Cape Cod and East Coastal Massachusetts repeaters for wind damage reports, coastal flooding reports and on Cape Cod and the Islands, snow accumulation reports..
Additional weather headlines were required for the powerful ocean storm due to its large and intense envelope and a slightly further west track of the storm center. The headlines above represent the current thinking. Key factors remain as follows:
1.) If the western wobble continues, it would put more areas Southeast New England at a greater risk for stronger and more damaging winds and higher accumulating snow. This will bear close watching through the day today.
2.) If the western trend in the guidance stops and stays roughly on the current track, the current scenario in the weather headlines will be the outcomes for this storm.
3.) A trend further east would mean less wind and little to no snow in the Cape Cod and Islands region.
SKYWARN Self-Activation will monitor storm impacts over Cape Cod and the Islands and East Coastal Massachusetts overnight through midday Saturday. In particular, we will monitor the Cape and Islands Weather Net Saturday Morning at 6 AM and monitor Cape Cod and East Coastal Massachusetts repeaters for wind damage reports, coastal flooding reports and on Cape Cod and the Islands, snow accumulation reports. Another coordination message may be posted if time allows by 1000 PM tonight particularly if there is any change to the current warning and advisory headlines otherwise, this will be the last coordination message as we shift into operations mode.
