Storm Coordination Message #2 – Sunday 10/12/25-Monday 10/13/25 Multi-Hazard Coastal Storm Potential
Hello to all…
..A coastal storm will bring portions of Southern New England, Heavy rainfall, strong to damaging wind gusts, coastal flooding and beach erosion late Sunday Afternoon to Monday Evening. Rainfall will be beneficial with 1-2″ of rain expected with higher amounts potentially as high as 2-4″ with isolated higher amounts across parts of Rhode Island and Southeast Massachusetts.
..A High Wind Watch remains in effect for Block Island, RI, Martha’s Vineyard and Nantucket Massachusetts for Sunday Afternoon through Monday Evening for sustained winds of 25 to 35 MPH with gusts to 60 MPH and isolated higher gusts possible. A Wind Advisory is in effect from 8 PM Sunday Evening to 8 PM Monday Evening for sustained winds 20-30 MPH with gusts to 50 MPH and isolated higher gusts possible. Coastal areas and interior areas of Eastern Massachusetts and Rhode Island outside of the Wind Advisory/High Wind Watch area could see wind gusts of 40-45 MPH with isolated higher gusts while inland areas see wind gusts 30-40 MPH with isolated higher gusts in the higher elevations. These winds could cause isolated to scattered pockets of tree, wire damage and power outages..
..A Coastal flood Watch remains in effect for East and South Coastal Massachusetts and Rhode Island for minor to moderate coastal flooding at the time of high tide across several high tide cycles from Sunday Morning to late Monday Night. This could result in shore road closures across vulnerable shore roads across the watch area..
..SKYWARN Self-Activation is likely with Amateur Radio Call-Up Nets possible to cover the various hazards from this coastal storm Sunday through Monday. Pictures and videos of storm damage, rain related flooding and coastal flooding can be sent as a reply to this message via the WX1BOX Facebook/X/Bluesky feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..
A coastal storm is on track to impact the region starting Sunday Morning with impacts at the coast from coastal flooding and then with heavy rainfall and strong to damaging winds especially at the coast but also impacting some areas inland from the coast. The headlines depict the current thinking. Key factors remain:
1.) The strength of the storm system and how the storm system organizes and whether its elongated or if its more of an energy transfer closer to the Southern New England coast from the North Carolina coast. This will determine how strong the wind gusts will be and how the rainfall organizes over the area. While we will certainly will have lower barometric pressure storm systems later this Fall and winter, the pressure gradient between the low pressure and high pressure to the north will be the cause of the strong wind gusts.
2.) How the precipitation field organizes and how far north it reaches will determine extent of rainfall amounts in the region.
3.) How the strongest winds coincide with the high tide cycles will determine the coastal flood potential and how widespread it will be.
