[Weather] [2019.10.16 AM] Strong to Damaging Winds Possible & Heavy Rain/Poor Drainage Flooding

[BOX Operations - NOAA Service Account]

Good morning everyone,

Here is our latest update on a powerful coastal storm to impact MA, RI & CT
tonight into Thursday morning.

*What/When & Where ...*

*Headlines ...*

   - *High Wind Watch - *Cape Cod & Islands Thursday
   - *Wind Advisories - *south coast of RI and eastern MA coast including
   Boston tonight then all of RI and eastern MA Thursday

*Strong to Damaging Wind Threat ...*

   - *When* - two surges of wind are expected with the first surge tonight
   (east winds) followed by a stronger surge Thursday morning and afternoon
   (west winds)
   - *Where* - RI into eastern MA but strongest wind over Cape Cod and
   Islands
   - *Impacts* - winds potentially strong enough to down tree limbs and
   result in power outages.  Greatest threat over Cape Cod and the Islands
   - *Uncertainty* - how much strong wind aloft will mix down to the
   surface and areal extent.  Trees remaining fully leaved will require less
   wind for damage to occur.

*Heavy Rainfall Threat & Poor Drainage Flooding ...*

   - *When* - Heaviest rain approximately 10 pm Wednesday to 6 am Thursday
   from southwest to northeast
   - *Where* - all of MA, RI and CT
   - *Impacts* - a widespread 1.5 to 3 inches of rain with localized
   amounts of 4 to 5 inches  possible. Given the relatively recent dry weather
   river and stream flows are running at or below normal.  Therefore the only
   flooding expected is poor drainage/urban-street flooding. What may minimize
   any flooding impacts is the heaviest rainfall is expected to occur in
   between rush hours, after the late day commute today and before the Friday
   morning commute
   - *Uncertainty* - areal extent of 4 to 5 inch rainfall amounts are
   uncertain.  Low and high end rainfall maps attached along with mostly
   likely rainfall amounts to help communicate this uncertainty
