Storm Coordination Message # 4- 2/10-2/11/2010 Major Winter Storm Event
Hello to all..
..Major Winter Storm to affect portions of Southern New England..
..A Winter Storm Warning is in effect from 8 AM Wednesday to 1 AM Thursday for Northern Connecticut, all of Rhode Island, Hampden, Hampshire, Central and Southeast Middlesex, Southern Worcester, Suffolk, Norfolk, Bristol, Plymouth Counties of Massachusetts and Cape Cod and Martha’s Vineyard. Amounts along and north of the Mass. Pike will be 4-9 inches with the higher amounts closer to the Pike. Amounts south of the Mass Pike will range from 9-15 inches with isolated higher amounts..
..A Winter Storm Warning is in effect for Nantucket Island from 3 PM Wednesday to 1 AM Thursday for 4-8 inches of snow. A snow, sleet, rain mix will hold down snow amounts and delay the storm in this area but warning criteria snowfall is still expected on Nantucket..
..A Winter Weather Advisory is in effect for Franklin, Northern Worcester, Essex and Northern Middlesex Counties of Massachusetts for 3-6 inches of snow. The Winter Storm Watch for Southern New Hampshire has been cancelled with only 1-3″ inches expected in this area with highest amounts closest to the Massachusetts state line..
..A High Wind Warning remains in effect for Cape Cod and the Islands from 6 PM Wednesday to 5 AM Thursday..
..The combination of potentially heavy wet snow especially at the coast and strong wind gusts of 40-55 MPH in Southeast New England with the potential for wind gusts as high as 60 MPH over Cape cod and the islands could result in power outages and tree and power line damage. These conditions could also cause a period of near blizzard conditions. All in the Winter Storm Warning and High Wind Warning areas should closely monitor the progress of this system..
..There could be a sharp cutoff of heavy snow versus lighter snow across the warning area where just 20-30 miles could make the difference between heavy snow accumulations and lighter amounts. This means some snowfall amounts over the northern parts of the region are lower confidence versus over southern parts of the region..
..SKYWARN Activation with Ops at NWS Taunton are likely starting at 10 AM Wednesday lasting through early Thursday Morning..
..ARES/RACES Groups should closely montior the progress of this significant coastal storm/nor’easter to impact Southern New England and seek advice from local leadership. Eastern Massachusetts ARES will be placed on stand-by starting at 10 AM Wednesday through Thursday Morning. RACES will be active at the Massachusetts State EOC. Also, have received word that Connecticut ARES is on a level-2 mode to monitor the storm situation…
Model runs continue to be similar on the track of the storm though their remains a sharp cutoff in the heavy snow versus lighter snows and the position of this sharp cutoff could cause snow amounts in the northern areas to be much too high or much too low depending on where this cutoff occurs. A difference of just 20-30 miles could make a huge difference in this cutoff. This message reflects the current thinking as o this morning.
A Winter Storm Warning remains in effect from 8 AM Wednesday through 1 AM Thursday over Northern Connecticut, Rhode Island and Southeast Massachusetts including Cape Cod and Martha’s Vineyard, Suffolk, Southern Worcester, Hampden and Norfolk County Massachusetts. This area is now expected to receive 9-15 inches of snow with isolated higher amounts possible to the south and amounts closer to 9″ in the northern part of the warning area. A Winter Storm Warning is now in effect for Central and Southeast Middlesex, and Hampshire Counties of Massachusetts from 8 AM-1 PM Thursday for 4-9″ of snow. In this part of the area the highest amounts are expected closest to the Mass Pike and there could be a sharp cutoff in heavier snowfall accumulations versus lighter amounts as stated previously.
On Nantucket Island, the Winter Storm Warning is now in effect from 3 PM Wednesday to 1 AM Thursday for 4-8 inches of snow. Precipitation will likely start as a period of mixed snow, sleet and rain before changing over to snow this afternoon and becoming heavy and wet. The wet snow clinging to trees and power lines along with potential wind gusts to 60 MPH could cause tree and power line damage in this area as well so a high impact is possible though snowfall amounts will be lower.
A Winter Weather Advisory is now in effect for Franklin, Northern Worcester, Essex and Northern Middlesex Counties of Massachusetts for 3-6 inches of snow with locally higher amounts in the southern parts of the advisory area. Across Southern New Hampshire, the Winter Storm Watch has been cancelled and only 1-3 inches of snow is expected there with the highest amounts near the Massachusetts border.
The storm will also have strong wind gusts up to 40 MPH in the interior portion of the Winter Storm Warning area with coastal areas of the Winter Storm Warning seeing winds of 40-55 MPH in gusts. Over Cape Cod and the Islands, a High Wind Warning is in effect from 6 PM Wednesday through 5 AM Thursday and in this area wind gusts of up to 60 MPH and possibly slightly higher could occur. The combination of the strong to damaging winds and the heavy wet snow potentially clinging to trees and power lines could result in tree and power line damage and power outages. This will be monitored closely. In addition, if the snow is falling heavy enough and not mixed with sleet and rain, a period of near blizzard conditions could occur in the Southeast New England portion of the Winter Storm Warning in particular. This will also be monitored closely.
Any coastal flooding is expected to be minor and would be on north and east facing coastline of East Coastal Massachusetts. The greatest risk for minor coastal flooding would be over the Outer Cape and Nantucket Island.
SKYWARN Activation with Ops at NWS Taunton will start at approximately 10 AM lasting through early Thursday Morning. Snowfall reports, changeover in precip type and damage reports from wet snow/wind and wind measurements will be very critical to providing situational awareness to emergency management and for NWS forecasters for the warning process. We appreciate SKYWARN Spotters activating and being on high alert for this storm particularly in areas along and south of the Mass. Pike.
ARES/RACES Groups should closely montior the progress of this significant coastal storm/nor’easter to impact Southern New England and seek advice from local leadership. Eastern Massachusetts ARES will be placed on stand-by starting at 10 AM Wednesday through Thursday Morning. RACES will be active at the Massachusetts State EOC. Also, have received word that Connecticut ARES is on a level-2 mode to monitor the storm situation.
