A strong coastal storm will affect Southern New England after ideal weather conditions for the 2022 Boston Marathon. The headlines depict the current thinking. Key factors include:
1.) The track of the storm system has settled into a location where some accumulating snow at elevations of 1500 feet are possible particularly in Northwest Franklin County where the Winter Weather Advisory is posted. Wet snow damage would be possible if 3″ or more occur with 40 MPH wind gusts.
2.) The track of the storm system will also impact the extent of the strong winds. On the current track, the current wind headlines are in place with High Wind Warnings for the Cape and Islands and Wind Advisories for East and South Coastal Massachusetts and Rhode Island.
3.) The strongest winds right now are expected to be between high tide cycles with a shift in wind direction but some splashover and possible pockets of minor coastal flooding are possible. A coastal flood statement has been issued focus on the early Tuesday Morning high tide cycle.
SKYWARN Self-Activation will monitor the coastal storm system for late Monday Night into Tuesday Morning. This will be the last coordination message on this storm event as we shift into operations mode.
