[Weather] [2018.12.18 PM NWS Briefing] Potential for Heavy Rainfall/Flooding and Strong Winds: Late Thu night into Fri night

[BOX Operations - NOAA Service Account]

Good afternoon,

We wanted to send a general heads-up email on a potential multi-hazard
storm for late Thursday night into Friday night. No wintry
precipitation/ice is expected, but heavy rainfall and associated flooding
impacts, strong winds and minor coastal flooding are possible. Here are the
details below.

*What / Where / When ...*

   - Heavy rainfall across all SNE
      - Rain starts late Thursday night, with heaviest rainfall expected
      during much of the day on Friday and possibly lingering into Friday
      evening.
      - Rainfall amounts of 1.5 to 3 inches, with locally higher amounts
      possible.
      - Heavy rainfall will likely result in urban and poor drainage
      flooding, along with some river flooding as well. Moderate river flooding
      is possible if rainfall approaches 3 inches.


   - Strong southerly winds
      - The greatest risk for strong to damaging winds will be across SE
      New Eng,  particularly RI and southeast MA and Cape/Islands during Friday
      possibly into Friday evening.
      - Potential for wind gusts over 50 mph.
      - If strong winds are realized, tree damage and isolated to scattered
      power outages will be possible.


   - Minor coastal flooding along the south coast
      - Mainly during the early Friday evening high tide.
      - Storm surge around 2 ft possible with 10+ foot seas just offshore.
      - Minor flooding possible along the shores of Narragansett Bay and
      Buzzards Bay, as well as splashover and minor flooding along
ocean exposed
      south coastal beaches.

*Uncertainty ...*

   - Heavy rainfall: High confidence that heavy rainfall will occur, but
   there is uncertainty with respect to where the axis of heavy rainfall will
   set up and timing of the heaviest rainfall.
   - Strong winds: Uncertainty with how strong the winds will get near the
   south coast and extent of any wind damage, and also the timing of the
   strongest winds.
   - Coastal flooding: There is uncertainty if there will be enough storm
   surge during the Friday evening high tide to produce minor flooding.

More details will be provided during the next dew days.
