...FLOOD WATCH REMAINS IN EFFECT THROUGH THIS EVENING...

The Flood Watch continues for

* a portion of South Florida, including the following areas,
  Broward, Collier, and Miami-Dade counties.  

* Through this evening.

* The passage of Potential Tropical Cyclone Seven will bring
  widespread rainfall amounts of 2 to 4 inches with locally higher
  amounts over the next 24 hours. 

* Potential Impacts: Areas subject to high rain rates over short
  periods of time will be susceptible, leading to flooding of
  canals, streets, and underpasses, as well as other drainage
  areas and low-lying spots. The hardest hit areas may see water 
  intruding on vulnerable structures and causing impassable travel
  lanes and roadways.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.

Area Forecast Discussion...UPDATED
National Weather Service Miami FL
736 PM EDT Sun Sep 2 2018

.AVIATION...
Potential Tropical Cyclone 7 is located over the Bahamas early
this evening. NHC is forecasting the system to move west northwest
tonight and be over the southeastern Gulf of Mexico by Labor Day
afternoon. This will allow for the winds over the taf sites to be
easterly with speeds increasing from around 10 to 15 knots this
evening to around 20 knots on Labor Day. The showers and
thunderstorms will also be on an increase late tonight into Labor
Day across all of the taf sites. Any shower or thunderstorm that
does move through will be capable of producing gusts to around 35
knots especially on labor day, except at KAPF taf site where it
could get up to around 40 knots. The ceiling and vis will also
fall down into the MVFR or even IFR conditions late tonight into
Labor Day over all of the taf sites.

AVIATION...54/BNB

.PREV DISCUSSION... /issued 646 PM EDT Sun Sep 2 2018/

DISCUSSION...

TONIGHT AND LABOR DAY: Convective activity has diminished across
South Florida early this evening, likely somewhat of a suppressive
effect of ahead of the newly minted Potential Tropical Cyclone
Seven. Isolated showers and storms will continue across the area
through the late evening hours, with many areas remaining dry.

Beyond late evening, the focus of the next 24 hours will be
Potential Tropical Cyclone Seven. Currently over the Bahamas, it
is forecast with good confidence to track across the Florida
Straits and into Florida Bay by midday Monday and further into the
eastern Gulf during the afternoon.

THREATS FOR SOUTH FLORIDA...

RAINFALL: This remains the main impact expected from this system.

A number of parameters remain favorable for high rainfall amounts;
the developing tropical cyclone, very high precipitable water
values, low-level SE winds 30-35 knots transporting this deep
moisture over South Florida, and favorable upper level divergence
on east side of upper low over western Cuba.

The quick forward speed of this system is expected to mitigate
the otherwise excellent heavy rain setup, keeping general forecast
a widespread 2-4", with the heaviest amounts focused along the
east coast. However, this pattern is also favorable for training
bands moving into the coast so significantly higher amounts are
not out of the question. The general time frame for the highest
rainfall amounts is between 06z- 18z, or 2 AM-2 PM. For now, no
Flood Watch has been issued given the ongoing lack of confidence
in a widespread threat.

WINDS: Probabilities remain low for sustained tropical storm force
winds across South Florida as the system is not expected to
strengthen to tropical storm force until is is moving away from
the region. However, gusts to TS force in squalls will be
possible, overspreading the region from SE to NW starting late
tonight.

TORNADOES: Climatology shows that systems moving NW or WNW across
the southeastern Gulf favor at least isolated tornadoes across the
FL peninsula. Model data supports this forecast, with 0-1km
helicities 50-100 m2/s2 from late tonight through Monday
afternoon, picking up along the western two thirds of the area
late evening into Monday night.

TUESDAY: PTC Seven is forecast to be a tropical storm as it moves
further northwest away from the Florida peninsula across the Gulf
of Mexico. Drier midlevel is expected to filter into South
Florida behind it as high pressure over the mid-Atlantic states
builds southeast into the western Atlantic and Florida. A few
trailing bands may linger into Tuesday morning, mainly along the
Gulf, but overall expect a return to our typical east flow pattern
of scattered night/morning east coast and afternoon/evening
interior and Gulf coast.

WEDNESDAY THROUGH SATURDAY: The mid-level ridge will continue at
least through Thursday, keeping precipitation coverage near normal
with prevailing NE-E wind flow. A low/mid level trough embedded
in the deep easterly flow over the western Atlantic is forecast by
the global models to move west and over Florida Friday and
Saturday, with a general increase in moisture and
rain/thunderstorm chances back into the likely range to end the
upcoming week.

MARINE...Potential Tropical Cyclone Seven will move from the
Bahamas through the Florida Straits late tonight, lifting
northwestward across the Gulf waters through the day on Monday.

Expect E-SE winds to increase to 20-25 knots over the Atlantic
late this evening, and across the Gulf waters late tonight into
early Monday morning. The current track of PTC Seven takes it
across the local Gulf waters and a strengthening system Monday
afternoon and evening, becoming a tropical storm in this
timeframe.

A Tropical Storm Watch is currently in effect for the offshore
Gulf waters, with Small Craft Advisories for the remainder of the
Atlantic and Gulf waters. Later forecasts may bring Tropical Storm
Warnings across the Gulf waters if PTC Seven continues along it's
current intensity forecast.

Conditions will deteriorate over all the waters late tonight,
with gusts to tropical storm force possible in squalls along with
rough seas. Gradually improving conditions beginning Tuesday and
lasting through the upcoming week.

AVIATION...SHRA and embedded TSRA will continue to stream across
South Florida this afternoon producing brief periods of SHRA with
gusty winds and lower visibilities. This activity continues
through the evening and gradually deteriorate tonight as a
tropical disturbance moves across S FL from the ATL. There will be
periods of low vis to MVFR/IFR due to moderate to heavy
downpours. Gusty winds up to 35 knots or higher could be possible.
PROB30 groups for MVFR periods remain in place for tonight.

BEACH FORECAST...Gusty onshore winds along the Atlantic beaches
will keep a high risk of rip currents at least through Labor Day,
and possibly through the middle of the week as winds stay onshore,
albeit at lower speeds.
