.DISCUSSION...
Forecast for tonight through Wednesday: Hurricane Matthew is
forecast to move generally northward tonight then northwestward
across the Southern Bahamas into Wednesday. As it does so, deep
tropical moisture and increasing cloudiness and steadily
increasing winds are expected across the region. Bands of showers
and scattered thunderstorms well in advance of the hurricane will
be possible tonight into Wednesday. By Wednesday afternoon and
evening more widespread showers and thunderstorms are forecast
across the Atlantic waters and Atlantic metro areas.
As of 11 AM EDT, a Hurricane Watch is in effect for portions of
mainland South Florida and portions of the Atlantic Waters. A
Tropical Storm Watch is in effect for portions of mainland South
Florida and portions of the Atlantic waters, including Biscayne
Bay and Lake Okeechobee. As for intensity and timing, Hurricane
Matthew is expected to be a major hurricane and is forecast to
cross the Bahamas on Wednesday and across the Northwest Bahamas on
Thursday.
With additional updates from the National Hurricane Center this
afternoon and evening, changes to the watches or potential
warnings are possible and all local products will be updated
accordingly.
Primary threats for South Florida: At this time primarily wind.
Additional threats include hazardous marine conditions and beach
erosion. Currently hurricane force winds are not forecast for the
South Florida peninsula, but given the uncertainties there still
remains a reasonable chance for portions of Broward and Palm Beach
counties.
Additional threats to South Florida, but more minor, include storm
surge, flooding rains and tornadoes. The forecast winds with
Matthew will not be favorable for storm surge inundation along the
Atlantic coastal zone. In general peak winds will be along or off
shore. Therefore, while storm surge is expected to be elevated
mainly along the Palm Beach county coast, forecast levels are
similar to inundations from astronomically high tides in flood
prone areas along the coastal zone. The flooding rain threat and
tornado threat, while elevated across portions of South Florida,
are also minor. For flood potential, while locally high rainfall
in isolated areas is entirely possible, the forecast of Matthew
indicates that as it gets closer to South Florida it is expected
to accelerate. This should aid in reducing potential rainfall
accumulations. For tornado potential, there will be an elevated
threat mainly across the eastern peninsula but it is not moderate
or high as the greatest threat for tornadoes is normally on the
northeast quadrant of the hurricane, and in this scenario South
Florida will be in the western to southwestern quadrants.
For the updated specifics to the track for Hurricane Matthew,
please consult the latest products from the National Hurricane
Center. For potential impacts for South Florida, please continue
to monitor products issued from the National Weather Service in
Miami.

.MARINE...
As hurricane Matthew approaches South Florida, extremely
dangerous and hazardous marine conditions are likely for the
local Atlantic waters beginning Wednesday night and continuing
through at least Friday. In addition, winds and waves will be
locally higher with bands of showers and thunderstorms well ahead
of Matthew.
&&
.AVIATION...
Afternoon convection has popped up west of the east coast
terminals, with APF possibly seeing more convection in the area
later in the afternoon. The potential exists for a secondary round
of thunderstorms after sunset along the east coast. Storms could
bring MVFR cigs and IFR/LIFR vsbys in heavy rain if they impact a
terminal directly.
&&
.BEACH FORECAST...
As Hurricane Matthew approaches the region Wednesday night,
conditions will rapidly deteriorate at all Atlantic beaches, with
dangerous conditions likely including life- threatening rip
currents, significant beach erosion, and significant waves and
swell. Coastal flooding due to wave set-up and run-up will also be
a threat and dependent upon the eventual track of Matthew,
especially across Broward and Palm Beach counties.
