Hello to all..
..Long Duration Storm System will Bring Heavy Rainfall, Several rounds of minor to possibly moderate coastal flooding, strong winds along coastal areas and even the potential for wintry precipitation in northwest areas. Storm will be long duration affecting the region from tonight through Monday Afternoon/Evening..
..A Flood Watch remains in effect from Saturday Evening through Monday Afternoon for Southern New Hampshire. A Flood Watch remains in effect from Saturday Evening through Monday Morning for Northern Connecticut, Western, Central and interior Northeast Massachusetts and Northwest Rhode Island..
..A Coastal Flood Advisory remains in effect for Southern Bristol County Massachusetts and Newport, Bristol and Eastern Kent Counties of Rhode Island from 6-10 AM Sunday for minor coastal flooding at the time of high tide on most exposed coastal areas for shore road flooding..
..A Coastal Flood Advisory is now in effect for East Coastal Massachusetts from 9 AM-2 PM Sunday for minor coastal flooding at the time of high tide. Additional tide cycles maybe affected Sunday Evening through Monday Evening..
..At this time, winds will stay below Wind Advisory through Sunday Afternoon with winds gusting perhaps up to 40 MPH but may now reach Wind Advisory criteria Sunday Evening into Monday Morning. This will be monitored as we get into Sunday..
..Northwest Massachusetts and Southern New Hampshire may seem some level of icing as cold air attempts to wrap into the system Sunday Night into Monday..
..SKYWARN Self-Activation will monitor for rainfall reports, and urban/poor drainage/river/stream flooding as well as the coastal flood threat through Sunday Morning. Ops at NWS Taunton are possible as well..
A long duration storm system will affect the region with a variety of weather impacts tonight through Monday Afternoon and evening. The impacts include, heavy rainfall and potential for urban and small stream/river flooding, minor to potentially moderate coastal flooding over multiple high tide cycles, strong winds and then wintry precipitation in Northwest Massachusetts and Southern New Hampshire Sunday Night into Monday. This coordination message will break down the impacts.
In the flood watch areas, there have been no significant changes to the forecast. Rainfall of 1-3″ with isolated higher amounts remain likely and with vegetation dormant, this may allow for urban, and small stream flooding. In northern parts of the Flood Watch area, there is also a low potential for ice jam flooding along rivers and streams. Areas outside of the Flood Watch area should monitor for typical urban and poor drainage issues from a likely 1-2″ of rainfall with isolated higher amounts.
For the Coastal Flood Advisory area, a round of minor coastal flooding is expected to impact the most vulnerable shore roads of South Coastal Bristol, Newport, Bristol and Eastern Kent Counties of Rhode Island during the Sunday Morning high tide cycle due to southerly wind flow. The minor coastal flood threat will then shift into East Coastal Massachusetts for the midday high tide cycle and a Coastal Flood Advisory has been extended into this region for that high tide cycle. As winds turn more Northeast to North-Northeast and strengthen, the potential exists for additional rounds of minor to potentially moderate coastal flooding over future high tide cycles for East Coastal Massachusetts. This will be monitored for those additional high tide cycles and part of the reason for the impacts are the high astronomical tides over this time period.
Strong winds up to 40 MPH will impact coastal areas through Sunday Morning. These winds may strengthen Sunday Evening into Monday potentially reaching Wind Advisory criteria. The strength of these winds may also impact the coastal flood potential for additional high tide cycles in East Coastal Massachusetts.
Finally, northwest Massachusetts and Southern New Hampshire could see a period of icing as colder air wraps into the system Sunday Night into Monday Morning. This will be updated in future coordination messages on this storm.
SKYWARN Self-Activation will monitor for rainfall reports, and urban/poor drainage/river/stream flooding as well as the coastal flood threat through Sunday Morning. Ops at NWS Taunton are possible as well for a portion of the storm system depending on the strength of the winds, coastal flood potential, urban/small stream flood potential and the winter weather potential for northwest parts of the area. The next coordination message will be posted by 10 AM Sunday Morning. Below are the NWS Taunton Flood Watch Statement, Coastal Flood Advisory Statement and Hazardous Weather Outlook:
