SITUATION OVERVIEW
------------------

Tropical Depression Fred is moving west-northwestward just north of
the coast of Cuba this morning and is forecast to approach the Florida
Straits and South Florida Saturday.

* The main threat from Fred to the local area will be the potential for
  localized flooding from excessive rainfall. A Flood Watch is in effect
  from tonight through Sunday night.

* Sustained tropical storm force winds are forecast over our Gulf
  waters and are possible over the immediate southwest coast.
  Elsewhere, tropical storm force wind gust is squalls and rain bands
  are possible .

* A few tornadoes will be possible as Fred moves through the eastern
  Gulf.

* Poor marine and beach conditions are also expected, with a heightened
  risk for rip currents and elevated surf along the Atlantic coast
  (especially on Saturday).

* The main window for the above impacts will be from late tonight
through Saturday night.

POTENTIAL IMPACTS
-----------------

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across South Florida. Potential impacts include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - Ditches and canals may quickly become swollen with swift
      currents and overspill their banks in a few places, especially
      in usually vulnerable spots.
    - Flood waters can enter some structures or weaken foundations.
      Several places may experience expanded areas of rapid
      inundation at underpasses, low-lying spots, and poor drainage
      areas. Some streets and parking lots take on moving water as
      storm drains and retention ponds overflow. Driving conditions
      become hazardous. Some road and bridge closures.

* WIND:
Prepare for hazardous wind having possible limited impacts across
coastal areas of southwest Florida.

Potential impacts in this area include:
    - Damage to porches, awnings, carports, sheds, and unanchored
      mobile homes. Unsecured lightweight objects blown about.
    - Many large tree limbs broken off. A few trees snapped or
      uprooted, but with greater numbers in places where trees are
      shallow rooted. Some fences and roadway signs blown over.
    - A few roads impassable from debris, particularly within urban
      or heavily wooded places. Hazardous driving conditions on
      bridges and other elevated roadways.
    - Scattered power and communications outages.

Elsewhere across South Florida, tropical storm wind gust are possible
in squalls and rainbands

* TORNADOES:
Prepare for a tornado event having possible limited impacts across
South Florida. Potential impacts include:
    - The occurrence of isolated tornadoes can hinder the execution
      of emergency plans during tropical events.
    - A few places may experience tornado damage, along with power
      and communications disruptions.
    - Locations could realize roofs peeled off buildings, mobile
      homes pushed off foundations or overturned, large tree tops and
      branches snapped off, shallow-rooted trees knocked over, moving
      vehicles blown off roads, and small boats pulled from moorings.

* SURGE:
Prepare for locally hazardous surge having possible limited impacts
across southwest Florida coastline during times of high tide.
Potential impacts in this area include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots, or in areas
      farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots become overspread
      with surge water. Driving conditions dangerous in places where
      surge water covers the road.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly
      in usually vulnerable locations. Strong rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

Elsewhere across South Florida, little to no impact is anticipated.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* OTHER PREPAREDNESS INFORMATION:
When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging wind
gusts, storm surge, and tornadoes extend well away from the center of
the storm.

Closely monitor weather.gov, NOAA Weather Radio and local news outlets
for official storm information. Listen for possible changes to the
forecast.
