   - *Strong coastal storm clipping eastern New England*.
      - A strong coast storm will clip eastern New England overnight into
      into Wednesday morning with associated hazards noted below.

   - *Strong to damaging winds ... *
         - North-Northeast winds increasing towards Wednesday morning, the
         strongest clipping southeast New England with gusts up as
high as 50 mph,
         especially for Nantucket.
         - Becoming westerly midday Wednesday and continuing overnight,
         gusts over much of Southern New England will be up as high as 55 mph,
         especially across the high terrain of Massachusetts.
         - WIND ADVISORIES posted for Nantucket (4 am to 1 pm Wednesday)

         - Especially for the Cape and Islands, rainfall amounts of 1 to 2
         inches are forecast. Worst case scenario, rainfall amounts
could exceed 3
         inches coming close to 3.5 inches.
         - Higher confidence for the threat of poor drainage flooding for
         the Cape and Islands, however should worse-case rainfall
amounts occur,
         there is a threat to Rhode Island and southeast Massachusetts.

   - *Wet snow ... *
         - We expect wet snow to develop around midnight and continue into
         the early morning hours on Wednesday over a good chunk of southern New
         England that includes northern CT, northern RI, central and eastern MA.
         - Greatest accumulations are likely over the higher elevations in
         and around the Worcester-metro area and points northward
towards the border
         - WINTER WEATHER ADVISORIES posted for Worcester and northern
         Middlesex County MA for around 2 to 3 inches of snow (1 am to 8 am
         Wednesday).
         - Worst-case scenario of 4 to 5 inch amounts.
         - Most of the snow is likely to melt and disappear by 10 am.

   - *Gale force winds ...*
         - A period of northeasterly gale force winds are forecast to
         develop shortly after midnight Wednesday continuing into
Wednesday morning.
         - As the coastal storm passes around midday, will see westerly
         gales develop that will continue into Wednesday evening.
         - GALE WARNINGS posted for all waters (2 am to 8 pm Wednesday).
         - Maximum wave heights of 12 to 15 feet are forecast, the height
         of which will occur late Wednesday into Wednesday evening.

   - There are no coastal flooding concerns.

   - *Fire Weather concerns for Western New England*.
      - An elevated fire risk will be in place for Wednesday for areas of
      Massachusetts within and west of the Connecticut and Pioneer
River Valleys.
      - Altogether, there is little to no snowpack, as well as forecast
      precipitation associated with a coastal storm impacting the
eastern half of
      New England for the aforementioned region.
      - Forecast midday to afternoon relative humidity will be as low as 25
      to 30 percent as strong, dry westerly winds are expected to be sustained
      around 20 mph with gusts around 35 to 45 mph.
      - The main concern is for areas of grass, shrub and dried leaf litter
      fuel types which could yield dangerous fire behavior with the
predicted dry
      and windy conditions.

Respectfully,
