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

[BOX Operations - NOAA Service Account]

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:*


   - Headlines have been changed from Watches to Warnings, except for an
   Advisory in Franklin County Massachusetts.
   - Correction to this e-mail to add graphics for expected max winds and
   for excessive rainfall outlook.

*Headlines:*


   -   *High Wind Warning *for all of  southern New England except Franklin
   County Massachusetts from Monday midday until Monday early Monday night.
   -   *Wind Advisory* for Franklin County Massachusetts from Monday midday
   until early Monday night.
   -   *Storm Warning *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 early Monday morning
through Monday early Monday night. 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.
