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

Eta is moving northeastward across the western Caribbean Sea and
is forecast strengthen into a tropical storm before it crosses Cuba
this weekend and approaches southern Florida late this weekend into
next week. Uncertainty with the specific track and intensity of Eta is
high which means that residents, visitors, and those with interests in
South Florida should remain aware of the latest forecast, check their
hurricane plans, and begin to undertake the necessary preparations.

The primary concern is the potential of heavy rainfall which could
lead to urban and flash flooding, tropical storm force winds over
portions of South Florida and the local waters, and deteriorating
marine conditions late this weekend into early next week. Isolated
tornadoes and waterspouts are also a secondary concern. Low-lying
coastal areas could also experience minor to moderate flooding due to
Eta. Regardless of the specific classification of this system, the
aforementioned threats will be a concern heading into next week.

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

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across east coast metro areas of 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.

Prepare for locally hazardous rainfall flooding having possible
limited impacts across interior and west coast metro areas of South
Florida.

* WIND:
Prepare for dangerous wind having possible significant impacts across
extreme southern portions of Miami-Dade and Mainland Monroe counties.
Potential impacts in this area include:
    - Some damage to roofing and siding materials, along with damage
      to porches, awnings, carports, and sheds. A few buildings
      experiencing window, door, and garage door failures. Mobile
      homes damaged, especially if unanchored. Unsecured lightweight
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater
      numbers in places where trees are shallow rooted. Several
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges, causeways, and access
      routes impassable.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines.

Also, prepare for hazardous wind having possible limited impacts
across rest of South Florida.

* SURGE:
Prepare for locally hazardous surge having possible limited impacts
across all of the coastal areas of South Florida. 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.

* 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.

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

* EVACUATIONS:
 WATCH/WARNING PHASE - Listen to local official for recommended
preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.


* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.

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.

If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low-lying or poor
drainage area, in a valley, or near an already swollen river, plan to
move to safe shelter on higher ground.

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