[Weather] [2020-04-13 AM] NWS Boston EM Briefing for Damaging Winds/Thunderstorms on Monday

[BOX Operations - NOAA Service Account]

Good morning everyone,


Here are our latest thoughts on the potential for damaging wind gusts and
heavy downpours today leading to some urban flooding potential. The
greatest time of concern is late this morning into early evening.


*Changes since the last update:*


   - Increased emphasis on chance for urban and poor drainage flooding in
   heavy downpours. Some small streams may approach Action Stage.
   - Added a Coastal Flood Statement for upper parts of Narragansett Bay
   including the city of Providence for the low risk of minor coastal flooding
   during today's mid day high tide

*Headlines:*


   -   *High Wind Warning *for all of  southern New England except Franklin
   County Massachusetts from midday until early tonight.
   -   *Wind Advisory* for Franklin County Massachusetts from midday until
   early tonight.
   -   *Storm Warning *in effect for the ocean waters from this morning
   into this evening
   -   *Coastal Flood Statement *in effect for upper portions of
   Narragansett Bay for the mid day high tide

*Damaging Winds:*



Southerly wind gusts of 55 to 70 mph are possible late this morning through
this evening, with sustained winds of 20-40 mph. 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. Isolated amounts up to 3 inches are
possible, especially where where any thunderstorms move through.



*Thunderstorms**:*



There is a low risk of an isolated thunderstorm this afternoon and early
tonight, mainly for western CT and MA. Some of these storms could become
severe bringing damaging winds.



*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, but the area of
   highest wind gusts is less certain. As of right now, the most likely areas
   are across northern CT, northern and central RI, and interior southeast MA
   including the city of Boston.


Thank you

Bryce Williams and Frank Nocera
