A strong ocean storm will track south and east of New England but then be blocked from passing complete out to sea and retrograde and loop around the 40 North/70 West benchmark. The headlines depict the current thinking. Key factors for this storm include:
1.) The track of the storm system and if gets near or inside the 40 North/70 West benchmark. That will determine the extent of the strong to damaging winds and coastal flooding in East Coastal and Southeast coastal Massachusetts. Right now, the track is going to be near or just southeast of the 40 North/70 West Benchmark which would support the current thinking.
2.) Predominantly rain is expected but some wet snow could mix in depending on how heavy the precipitation is and if it allows for the column to cool sufficiently for wet snow to occur. At this time, little to no snow accumulation is expected.
3.) Rainfall of 1″ or more could occur particularly in Eastern New England. Somewhat higher amounts could occur if the track is closer to the coast then current thinking but right now the current thinking is for 1″ or more along parts of East Coastal Massachusetts, Cape Cod and the Islands.
SKYWARN Self-Activation will monitor for strong to damaging wind, coastal flood potential and for any rainfall amounts 1″ or more. This will be the last coordination message as we shift into self-activation operations mode unless a significant change occurs and time allows for an update.
