Area Forecast Discussion
National Weather Service Miami FL
246 PM EST Wed Nov 11 2020

..TORNADO WATCH FOR COLLIER COUNTY THROUGH 5PM EST TODAY...
..FLOOD WATCH FOR GULF AND EAST COAST CONTINUES...

Short Term (Rest of Today through Tomorrow):

Key Points:

1) A Tornado Watch is in effect for Collier County and the adjacent
Gulf waters until 5 PM EST today

2) A Flood Watch is in effect for Collier, Hendry, Glades,
metro/coastal Palm Beach, Broward, and Miami-Dade Counties until 7
PM EST tomorrow

The outer bands of Tropical Storm Eta continue to push towards
Southwest Florida this afternoon with the production of light to
moderate rainfall. As Eta continues to pull northward and away from
South FL, low-level winds will continue to veer to a more southerly
direction which will continue the influx of deep tropical moisture
areawide. In fact, forecast PW's are expected to reach almost 2.5
inches along the west coast this afternoon before pushing towards
the east coast this evening/overnight. These anomalously high values
are 3.4 to 3.7 standard deviations above normal and in the MAX
percentile for this time of year.

MFL's 11/18Z special sounding showed a modest decrease in CIN across
the region and a similar CAPE due to the moisture advection in the
area. Low-mid level lapse rates also slightly steepened.
Mesoanalysis shows increasing helicity values as well- SFC to 500m
SRH values of 50 to 100m2/s2 across portions of the west coast with
SFC to 3km SRH values of 100 to 200m2/s2. The increasing SRH, shear,
CAPE, moisture and the decreasing CIN profile across South FL will
lead to heavy rainfall with gusty winds and a few possible
tornadoes. These gusty winds may even approach severe criteria (at
least 58 mph) this afternoon. Therefore, the Flood Watch continues
for portions of South Florida as well as a Tornado Watch for Collier
County.

As we transition into the evening into the overnight hours, the
east coast becomes the main area of concern as the moisture tail
of Eta slides through (noted by the aforementioned eastward spread
of increasing PW's) and a band of convergence looks to set up.
Mostly cloudy skies thus far today has limited significant heating
across the east coast, though a few cloud breaks here and there
have been observed off GOES-16 visible satellite imagery. If cloud
breaks become more frequent, then instability will increase and
stronger showers and storms can be expected. Due to lower
confidence and highly conditional parameters, the potential for
the stronger showers and storms along the east coast could produce
strong, gusty winds and heavy rainfall. Any additional rainfall
over the east coast will cause flooding problems particularly in
areas that have still not drained from the heavy rainfall the past
few days. It will not take much rain to warrant a Flood Warning.

By tomorrow, deep moisture begins to subside as as the highest
values push eastward of the peninsula. With that said, it will
still take time for PoPs to lower (with short term PoPs lingering
in the 20 to 50 percent range) though it will generally decrease
from west to east throughout the course of the day. The main
hazard for tomorrow will be more of the heavy rain threat,
particularly for the east coast areas as standing water persists
and heavy rainfall is expected later today.

.Long Term(Friday Through Tuesday)

Rain chances remain in the forecast for the very start of the
extended period as a swath of lingering moisture trails in Eta's
wake as the storm finally departs the region. Thankfully, high
pressure at the surface and aloft build across the region through
the weekend, ushering in long-awaited drier conditions. While this
should limit deep convective initiation, can't rule out a few
isolated showers each afternoon.

Early next week, ridging aloft becomes shunted eastward as a
robust upper-level trough sweeps across the northern CONUS,
inciting cyclogenesis over the Upper Midwest. Current model
solutions depict a formidable cold front dropping southward across
South Florida as the surface low progresses quickly off towards
the northeast. Rain chances look to increase ahead and along the
boundary, albeit, the finer details are subject to change as there
is familiar variability between the timing, location, strength,
and position of the surface low and attendant cold front. This
will certainly be monitored with each forecast cycle. That said,
we could finally see a reprieve from our extended Summer with
slightly below average temperatures and tolerable humidity values.
Additionally, brisk northeasterly winds in the front's wake could
lead to hazardous marine and beach conditions for the Atlantic
waters and coastline.

&&

.Marine...
Tropical Storm Eta is forecast to move north-northeast across the
eastern Gulf of Mexico today and tonight, then approach the Big
Bend coast of Florida on Thursday before moving inland across
North Florida by the end of the week. Tropical storm conditions
are possible over the Gulf waters through at least tonight. Gusty
winds and locally rough seas will continue over the Atlantic
waters through Thursday. High pressure is then expected to build
over Florida from the east for the end of the week and upcoming
weekend, with gradually improving marine conditions by that time.

&&

.Aviation (18Z Tafs)...
Outer rainbands of Eta continue to impact KAPF and western
portions of South Florida. Heavy rainfall and gusty winds in the
rain bands. Southeast to southerly breezy conditions will continue
to prevail across all sites with VCSH, with increasing rain
chances later this evening and overnight for the east coast sites.
Intermittent BKN MVFR ceilings across the area but not prevailing
enough to include for now. SHRA and TSRA that move over any
terminals will be handled with TEMPOS.

&&

.Beach Forecast...
A high risk of rip currents continues for all southern Florida
beaches through at least Thursday. Additionally, a Coastal Flood
Advisory is in effect for the beaches of Collier County with the
expectation of minor coastal flooding during high tides today. The
Atlantic Coast beaches have a Coastal Flood Statement in effect.

&&

.Hydrology...
Additional rainfall tonight and Thursday over the hardest hit
areas of SE Florida raises the concern for aggravated flooding
conditions. Current QPF values are generally under 1 inch, with
the exception of east Miami-Dade and southeastern Broward
counties, but given the highly uncertain nature of the exact
location of the rain bands and the changing nature of Eta, as well
as the upward trend in PoPs, the Flood Watch has been extended
through Thursday evening.

...Tropical Storm Warning in effect for Collier County Gulf waters...

This hazardous weather outlook is for South Florida.

.DAY ONE...TODAY AND TONIGHT

Rip currents: There is a high risk of rip currents across all South
Florida beaches.

Thunderstorms: Isolated to scattered thunderstorms are possible
especially over the western areas of South Florida including the
Adjacent coastal Gulf waters.

Waterspouts: Waterspouts will be possible across all South Florida
waters with the best coverage over the Gulf waters.

Coastal Flooding: Minor saltwater flooding of low-lying land regions
may occur along coastal Collier County.

Flooding: Flooding of roadways continues across South Florida,
especially for the metro areas of South Florida. Any additional
flooding may be possible if heavy rainfall occurs over these areas.

Marine: Small Craft Advisories are in effect for winds and seas
across Gulf, Atlantic, Biscayne Bay, and Lake Okeechobee Waters.
Tropical storm warnings remain in place for portions of the Gulf
waters adjacent to Collier County.

Tornadoes: Tornado Watch is in effect for Collier County through
this afternoon. Rest of South Florida could see an isolated tornado
with any shower or thunderstorm that does develop.

Wind: Gusty winds up to 40 mph are possible with any showers or
thunderstorms, except for Collier County where the winds could get
up 60 mph.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

Residual flooding of roadways and neighborhoods is possible as it
will take time for the rainfall accumulations to recede. Also, any
additional rainfall from showers and storms will over already
saturated soils will result in flooding concerns.

Hazardous marine conditions will remain across the area through mid-
week, particularly over the offshore Gulf waters with Tropical Storm
Eta forecast to move northward.

Elevated risk of rip currents across all South Florida beaches
through much of the week ahead.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is requested for the western areas of South
Florida today. Rest of South Florida, widespread spotter activation
is not anticipated, however individual spotters are encouraged to
report high wind, hail and flooding to the National Weather Service
forecast office in Miami.
