Storm Coordination Message #3 – Monday 1/23/17-Tuesday Morning 1/24/17 Coastal Storm Potential
Hello to all…
..Updated headlines for the High Wind Watch for Plymouth and Eastern Essex Counties of Massachusetts and item 1 regarding the wind headline changes. Remainder of the coordination message is unchanged..
..Significant Coastal Storm will impact Southern New England Monday into early Tuesday with heavy rain, strong winds in the interior and strong to damaging winds at the coast, the potential for minor coastal flooding at the time of high tide and the potential for accumulating snow and ice in Northwest and North-Central parts of Massachusetts..
..A High Wind Warning remains in effect for Cape Cod and the Islands for sustained winds of 35-45 MPH with gusts in the 60-70 MPH range from 9 AM Monday to 6 AM Tuesday. These winds will likely cause scattered pockets of tree and wire damage and scattered power outages. A High Wind Watch is now in effect for Eastern Essex and Plymouth Counties of Massachusetts from Monday Afternoon through late Monday Night for sustained winds of 20-30 MPH with wind gusts 50-60 MPH and these winds could cause isolated to scattered pockets of tree and wire damage and isolated power outages. Additional wind headlines will likely be issued across much of Southern New England as we get closer to the storm event, specifically Wind Advisories for much of the rest of Eastern New England. These strong winds outside the High Wind Warning area could bring isolated to scattered pockets of tree and wire damage and isolated to scattered power outages..
..A Flood Watch is now in effect from Monday Afternoon through Tuesday Morning for Rhode Island and Eastern Massachusetts except for Cape Cod and the Islands for heavy rainfall of 2-3″ with higher amounts possible in areas where heavy rain trains over the same area. This could bring some urban and poor drainage flooding to portions of the region and small river and stream flooding if amounts of more than 3″ occur in a short enough period of time..
..Astronomical tides are very low on Monday Evening and somewhat higher on Tuesday Morning but still on the low side. The seas and wave action may bring some minor coastal flooding at the time of high tide along East Coastal Massachusetts and Cape Cod and the Islands depending on the strongest winds and fetch over the region..
..Some accumulating snow and/or ice is possible to likely particularly along the New Hampshire border in Franklin and Northern Worcester Counties extending down into the east slopes of the Berkshires in Western Franklin, Western Hampshire and Western Hampden Counties of Massachusetts..
..SKYWARN Activation with Ops at NWS Taunton are likely Monday through Monday Night. SKYWARN Self-Activation maybe needed Tuesday Morning for any coastal flood concerns depending on the speed of the storm system through the region..
This is the third in a series of coordination messages posted this weekend on a significant coastal storm that will impact the region. The headlines depict the current potential impacts from this storm system which is multi-faceted in nature. There are a number of key details that need to be worked out at this juncture as well as some items that are very high confidence at this time. They are the following:
1.) The very strong to damaging winds at the coast line is very high confidence currently. This will bear watching for any extent of power outages. High Wind Watches have now been posted over Eastern Essex and Plymouth Counties Massachusetts from Monday Afternoon into Monday Night for sustained winds of 20-30 MPH with gusts to 50-60 MPH. Wind Advisories will likely be issued for much of Eastern Massachusetts and Rhode Island in future forecasts. A High Wind Warning remains in effect for Cape Cod and the Islands where sustained winds of 35-45 MPH with gusts to 60-70 MPH could cause scattered pockets of tree and wire damage and scattered power outages.
2.) How much snow and ice can occur in far inland areas of Northwest and North-Central Massachusetts. There isn’t a lot of cold air available but if there is enough cold air for the heaviest precipitation, it could allow for either significant wet snow or icing in these areas and the details here have yet to be worked out and will depend on how cold the lower levels of the atmosphere becomes as the intense coastal storm tracks to our region.
3.) Confidence has increased in widespread heavy rainfall of 2-3″ with the potential for higher amounts in bands across a portion of Eastern New England. This has resulted in flood watches being posted for Rhode Island and Eastern Massachusetts except for Cape Cod and the Islands from Monday Afternoon through Tuesday Morning.
4.) Tides will be astronomically low but the easterly fetch and the strength of the winds may compensate enough if there is enough of a surge to result in minor coastal flooding at the time of high tide pending the strength of the strongest winds. The tide Monday Evening is about 1 foot lower than Tuesday Morning and the speed of the coastal storm and its coincidence with high tide will determine the extent of any minor coastal flooding and these details could still change as a 6-12 hour time difference will change the extent of any coastal flooding.
SKYWARN Activation with Ops at NWS Taunton are likely Monday through Monday Night. SKYWARN Self-Activation maybe needed Tuesday Morning for any coastal flood concerns depending on the speed of the storm system through the region. Another coordination message will be posted by 1130 PM Sunday.
