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

Tropical Depression Eta located across the western Carribean Sea
will continue to move northeast today and strengthen to a Tropical
Storm by this afternoon or evening. Eta is forecast to move toward
central Cuba by Sunday afternoon and then north and northwest toward
the Florida Keys by Sunday night and Monday.

As Eta moves closer to east central Florida the wind field will expand
and allow stronger winds to affect much of east central Florida Sunday
into Monday. The strongest winds are expected to develop along the
coast with windy conditions also developing across the interior Sunday
into Monday. A Tropical Storm Watch is now in effect for Indian River,
Saint Lucie and Martin counties. A Tropical Storm Watch means tropical
storm force winds with sustained winds of 40 mph may develop across
the Watch area during the next 48 hours.

The expanding wind field will also bring stronger winds to the Brevard
and Volusia coastal areas with sustained winds of 25 to 35 mph
developing with stronger gusts to 40 to 50 mph near the coast. Winds
across the interior counties of east central Florida will also become
windy up to 20 to 30 mph.

Wind gusts as high as 50 to 60 mph will be possible Sunday night and
Monday as heavier showers and isolated storms stream onshore from the
Atlantic. The stronger wind gusts are expected mainly along the
coastal counties with wind gusts to 50 mph possible farther inland
with fast moving squalls.

The frequency and coverage of showers and isolated storms will
increase Sunday into Monday as Eta makes it closest approach to east
central Florida. The heaviest persistent outer rainbands are expected
to affect the Treasure Coast and Okeechobee counties where daily
rainfall totals of 2 to 3 inches are expected Sunday and Monday with
cumulative rainfall amounts up to 4 to 6 inches. A Flood Watch is in
effect for Okeechobee, Indian River, Saint Lucie and Martin counties.
The expected heavy rainfall may cause localized flooding, especially in
poor drainage areas.

Marine conditions will become extremely hazardous through the weekend
and on Monday with high surf developing along the Atlantic coast.
Moderate beach erosion and minor coastal flooding may also develop by
Sunday night into Monday near the times of high tide. Large breaking
waves and strong rip currents are expected today which will be
hazardous to anyone entering the surf.

An isolated tornado may develop with fast moving showers that move
quickly onshore late Sunday night into Monday.

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

* WIND:
Prepare for hazardous wind having possible limited impacts across the
Treasure Coast. 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.

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across Okeechobe county and the Treasure Coast. Potential impacts
include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - Rivers and tributaries may quickly become swollen with swifter
      currents and overspill their banks in a few places, especially
      in usually vulnerable spots. Small streams, creeks, canals, and
      ditches overflow.
    - 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.

* SURGE:
Prepare for locally hazardous surge having possible limited impacts
across along the east central Florida coast. 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.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across
East Central 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, chimneys
      toppled, 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:
Evacuations are not expected at this time.

* 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.

When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.

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

There is a threat from tornadoes with this storm. Have multiple ways
to receive Tornado Warnings. Be ready to shelter quickly.
