Storm Coordination Message #2 – Tuesday 10/26/21-Wednesday 10/27/21 Coastal Storm Potential
Hello to all…
..Powerful coastal storm will have the potential for significant impacts of significant rainfall and the potential for urban, poor drainage, river and stream flooding to flash flooding across all of Southern New England, damaging winds across Eastern Massachusetts and Rhode Island and minor coastal flooding across multiple high tide cycles across East Coastal Massachusetts, Cape Cod and the Islands..
..A High Wind Watch is now in effect for Tuesday Morning through Wednesday Afternoon for all of Rhode Island, Eastern Essex, Suffolk, Southeast Middlesex, Norfolk, Bristol, Plymouth, Barnstable, Dukes and Nantucket Counties of Massachusetts for sustained winds of 25-35 MPH with gusts to 60 MPH and isolated higher wind gusts possible. These winds with fully leaved trees and heavy rainfall and wet conditions will have the potential to cause scattered pockets of tree and wire damage and scattered power outages..
..Additional watches and warnings may be required as we get closer to this powerful coastal storm event..
..SKYWARN Self-Activation will monitor the significant coastal storm potential for Tuesday into Wednesday..
After a relatively quiet stretch of weather, a powerful coastal storm will take aim on Southern New England Tuesday Morning into Wednesday Afternoon. The headlines depict the current thinking. Key factors include:
1.) How close the coastal storm approaches. This will depict how far inland strong to damaging winds will occur and also if even stronger winds will occur in coastal areas if the storm track is closer.
2.) Heavy rainfall of 3-6″ with scattered higher amounts are likely across much of Southern New England. The axis of heaviest rain within the region will depend on the track, speed and intensity of the coastal storm.
3.) While the tidal cycle is not astronomically high, the coastal storm track and slow speed of motion while intensifying could allow for multiple high tide cycles of coastal flooding. This will become better defined in future outlooks.
SKYWARN Self-Activation will monitor the significant coastal storm potential Tuesday into Wednesday. Another coordination message will be posted by 11 PM EDT Monday Evening.
