Storm Coordination Message #3 – Sunday Evening 12/10/23-Monday Morning 12/11/23 Multi-Hazard Storm System
Hello to all…
..Significant Multi-Hazard Storm on track to impact Southern New England Sunday Night and Monday Morning with the potential for strong to damaging winds, heavy rainfall leading to river/stream/urban flood potential, and the potential for minor to low-end moderate coastal flooding at the time of high tide across portions of South Coastal Rhode Island & Massachusetts..
..A Flood Watch has been expanded and is now in effect for the entire NWS Coverage Area except for Cape Cod and the Islands from Sunday Afternoon to Monday Evening for 2-4″ of rain with locally higher amounts potentially leading to flooding of small rivers, streams and urbanized areas..
..A High Wind Watch remains in effect for Late Sunday Night into Monday Afternoon for sustained winds of 35-45 MPH with gusts to 65 MPH and isolated higher wind gusts possible. A Wind Advisory is now in effect from 8 PM Sunday Evening to 9 AM Friday Morning for Eastern and Southern Plymouth, Southern Bristol County Massachusetts, Newport and Washington Counties of Rhode Island for sustained winds of 30-40 MPH with gusts to 50 MPH and isolated higher gusts possible. These winds will have the potential to cause scattered pockets of tree and wire damage with scattered power outages possible. Additional portions of Southern New England could have some wind headlines in future updates..
..A Coastal Flood Watch remains in effect from late Sunday Night through Monday Morning for Southeast Providence, Bristol, Eastern Kent, Newport and Washington Counties of Rhode Island for minor to pockets of moderate coastal flooding at the time of high tide along vulnerable shore roads in Southern Rhode Island. Additional coastal flood headlines are possible in future updates..
..Some snow is possible Monday Morning into the early afternoon for portions of the higher elevations in Northern and Western Massachusetts. Its a bit early to determine amounts at this time and will be updated in future updates..
..SKYWARN Self-Activation with monitoring of Amateur Radio Repeaters is likely late Sunday Night through Monday Morning for reportable criteria on rain gauge reports, rain related flooding, coastal flooding, wind damage and measured wind gusts 40 MPH or Greater. Pictures and videos of storm damage, coastal flooding, river, stream or urban flooding can be sent as a reply to this email, via our WX1BOX Facebook and/or Twitter feeds or via the email address email@example.com with credit given to the SKYWARN Spotter/Amateur Radio Operator unless otherwise indicated..
A significant multi-hazard storm has potential to bring impacts to Southern New England Sunday Night through Monday Morning. The headlines depict the current thinking. Key factors include:
1.) How much winds will be able to mix down to the surface in Cape Cod and the Islands and coastal Southern New England as there are very strong winds aloft. Some models had backed off slightly on the winds earlier today but high resolution models are indicating stronger winds in this area and in other parts of Southeast New England and this bears watching if that trend continues.
2.) If a convective line of showers or thunderstorms forms and further supports mixing down of damaging winds to the surface and also enhances heavy rainfall.
3.) Strength of the low pressure system as it moves over Southern New England as that could also impact the strength of the winds. Again, some models had the low pressure a bit weaker this morning but that trend has reversed a bit in the latest model runs.
4.) The biggest through for any changeover to snow on the back end of the system is in Northern New England but will need to monitor the higher elevations of Northwest and North-Central Massachusetts for any precipitation changeover.
5.) Axis of heavy rainfall and whether it can cause river, stream and/or urban flooding in the Flood Watch area. Confidence is growing in potential flooding
SKYWARN Self-Activation with monitoring of Amateur Radio Repeaters is likely late Sunday Night through Monday Morning for reportable criteria on rain gauge reports, rain related flooding, coastal flooding, wind damage and measured wind gusts 40 MPH or Greater. The next coordination message will be posted by 1100 AM Sunday Morning.
