[Weather] [2019.10.30 AM] Strong to Damaging Winds for the South Coast, Cape and Islands Thursday Night into Friday Morning

[BOX Operations - NOAA Service Account]

Good morning,

A strong frontal system is expected to approach our area later tonight into
Thursday, producing periods of light rain starting late tonight.

However, the period of greatest impact is from later Thursday night into
Friday morning, with a period of strong to damaging winds across the South
Coast and the Islands, and a period of heavy rain accompanying a cold
frontal passage.

*Changes with this update:*

   - *High Wind Watch Issued*: For southern Bristol and Plymouth Counties,
   Cape Cod and the Islands in Massachusetts, and for Block Island and Newport
   Counties in Rhode Island. In effect from late Thursday night through Friday
   morning.
   - *Gale Watch Issued:* For all coastal and offshore waters. In effect
   from 7 PM Thursday through 7 PM Friday.


*Details:*

      *Winds:*

   - *Timing:* Winds increase markedly Thursday evening. For the High Wind
      Watch area, the period of strongest winds during the pre-dawn
hours Friday
      into mid-Friday morning. Breezy to gusty winds could occur in
the interior
      after the cold front passes in the morning hours Friday.
      - *Peak Wind Gusts*: Southwest winds between 40-50 mph, up to 60 mph
      possible in the High Wind Watch area. Elsewhere, peak winds will
be in the
      30-40 mph range.
      - *Impacts:* Trees and power lines may be downed, resulting in power
      outages in the High Wind Watch area. Difficult travel for high profile
      vehicles.
      - *Uncertainty:* Strong winds will be present just off the surface,
      though it is not clear how much of these winds will translate to the
      surface. A line of heavy showers co-located with the front could
help focus
      areas of stronger winds near or potentially just outside of the current
      High Wind Watch area. After the front clears the region, there is a
      limited/low potential for west winds to produce sporadic/minor tree limb
      damage Friday morning in the interior.

      *Rain:*


   - *Timing*: Rain beings tonight. Period of heaviest rain, possibly
      accompanied by a rumble or two of thunder, is mainly overnight Thursday
      night into Friday in line with the cold front.
      - *Amounts:* Around 1 to 1.5 inches.
      - *Impacts*: Limited. Isolated poor drainage flooding possible from
      leaf-clogged storm drains.
      - *Uncertainty*: Areas of thunder could enhance rainfall rates,
      though this potential would be mainly southeast of I-95.
