[Weather] [2020-04-12 AM] NWS Boston EM Briefing for Damaging Winds/Thunderstorms on Monday

[BOX Operations - NOAA Service Account]

Good morning,



We continue to forecast the potential for damaging wind gusts and power
outages on Monday. The greatest time of concern is late Monday morning
into early Monday evening.


*Changes since the last update:*


   - None


*Headlines:*


   -   *High Wind Watch* for all of  southern New England from Monday
   morning until Monday evening
   -   *Storm Watch* in effect for the ocean waters from Monday morning
   into Monday evening

*Damaging Winds:*



Southerly wind gusts of 55 to 70 mph are possible late Monday morning
through Monday evening, with sustained winds of 20-40 mph. Greatest time of
concern is late Monday morning into early Monday evening. The highest winds
are expected across Rhode Island and southeast Massachusetts including Cape
Cod and the Islands, but damaging wind gusts are possible across all of
southern New England.



*Heavy Rain:*



Rainfall amounts of 1 to 2 inches are possible from late Sunday night
through Monday. Locally higher amounts are possible where any thunderstorms
move through.



*Thunderstorms**:*



Thunderstorms will be possible ahead of a cold front Monday afternoon and
early Monday night. Some of these storms could become severe bringing
damaging winds, lightning and heavy rain.



*Impacts:*

   - Scattered to widespread power outages are possible due to downed
   trees, tree limbs and power lines. Difficult travel for high profile
   vehicles.
   - Heavy rain may cause brief localized urban and poor drainage flooding.


*Uncertainty:*

   - We are confident in strong to damaging wind gusts Monday, but the
   magnitude of the wind gusts is still uncertain. If we end up on the lower
   end with mainly 50 to 60 mph wind gusts, we will have scattered power
   outages. On the other hand, if wind gusts end up in the 60 to 70 mph range,
   widespread power outages would be possible.



Thanks

Bryce Williams and Frank Nocera
