Storm Coordination Message #2 – Late Tuesday Night 4/2/19-Wednesday Morning 4/3/19 Coastal Storm Potential
Hello to all…
..Coastal storm to bring strong to damaging winds, heavy rainfall and a period of wet snow to portions of Southern New England..
..A Winter Weather Advisory is now in effect from 1-8 AM EDT Wednesday for Worcester and Northern Middlesex Counties of Massachusetts for 1-4″ of snow with the highest amounts at elevations of 1,000 feet or higher. If snow amounts get above 4″, isolated pockets of tree and wire damage would be possible from the wet snow in these areas. Other interior locations south and east of the advisory area from Norfolk County, Suffolk County area of Massachusetts, Northern Rhode Island and Northeast Connecticut to the advisory border could see a coating to 2″ of snow..
..A Wind Advisory is in effect for Nantucket from 4 AM to 1 PM Wednesday for sustained winds of 25-35 MPH with wind gusts to 50 MPH. These winds will cause isolated pockets of tree and wire damage and isolated power outages. Cape Cod could see wind gusts to at least 45 MPH with possibly higher gusts. This area will also be monitored for stronger winds if a closer approach for the storm allows for higher wind speeds..
..Will monitor heavy rainfall for any minor urban/poor drainage flooding issues with the potential for 1-2″ of rain in Southeastern New England with isolated higher amounts possible..
..A Wind Advisory is in effect for Western, Central, and Northeast Massachusetts from Norfolk County and the Greater Boston area through Southeast New Hampshire for sustained winds of 15-25 MPH with gusts to 50 MPH and isolated higher wind gusts possible. These winds will cause isolated pockets of tree and wire damage and isolated power outages..
..SKYWARN Self-Activation will monitor the storm system for Wednesday for snowfall reports, precipitation type changeover, criteria rainfall reports and criteria wind gusts, wind damage information including during the late overnight hours through the Wednesday Morning commute timeframe and then in the afternoon/early evening for the strong wind potential..
A coastal storm will track close enough to Southern New England to bring heavy rainfall to Southeast New England and rain changing to snow to portions of Southern New England. Strong to damaging winds will likely occur on the Cape and Islands first and then will affect much of interior Massachusetts later in the day. The headlines reflect the latest thinking. Key factors include:
1.) How quickly the rain changes to snow in portions of Central New England and how effectively it accumulates during the overnight hours if it falls heavily. A closer storm track would bring the potential for snowfall amounts greater than 4″ and a chance for isolated tree and wire damage and power outages from wet snow.
2.) Strong winds on Cape Cod and the Islands and Southeast New England during the morning and early afternoon hours as there is the potential for stronger wind gusts than currently posted depending on the storm track and how effectively the winds can reach the surface. This will be monitored closely.
3.) Heavy rainfall over South Coastal Massachusetts, Rhode Island and Cape Cod and the Islands and the potential for urban and poor drainage flooding depending how quickly the rainfall occurs in this area.
SKYWARN Self-Activation will monitor the storm system for Wednesday for snowfall reports, precipitation type changeover, criteria rainfall reports and criteria wind gusts, wind damage information including during the late overnight hours through the Wednesday Morning commute timeframe and then in the afternoon/early evening for the strong wind potential. This will be the last coordination message for this system and a significant update occurs and time allows for an update.
