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

Dangerous Hurricane Irma is moving northward over western interior
Florida, and will move a little closer to east central Florida than
previously forecast through tonight!!!

The large area of hurricane force wind gusts will produce sustained
winds at or near hurricane force with gusts 80 to 100 MPH across the
entire region, with gusts to around 110 MPH near the eastern eyewall,
which will be moving near or across Lake County.

Dangerous, life-threatening conditions are expected over the next 6 to
12 hours! Widespread extensive wind impacts will continue as damaging
wind gusts to hurricane force are a significant concern for all of east
central Florida. Recent peak wind gusts include 99 MPH at the Saint
Lucie Power Plant, 89 MPH at the Treasure Coast International Airport
in Fort Pierce, 81 MPH at Cape Canaveral Air Force Station, 76 MPH at
Orlando International Airport, 75 MPH at Grant/Valkaria, 69 MPH at the
National Weather Service Office in Melbourne, and 63 MPH at the
Sanford and New Smyrna Beach Airport.


If you are in an area prone to flooding, be prepared for the
possibility of a quick and dramatic rise in water levels. Rainfall
totals of 6 to 12 inches have been recorded over much of the area with
isolated amounts of 15 to 20 inches Across Brevard, Indian River, and
Saint Lucie Counties. An additional 6 to 10 inches of rain is expected,
mainly farther from Osceola and Brevard Counties northward. This will
cause further rapid rises of small streams, creeks, canals, and ditches
as well as extensive flooding of area roadways.

The threat for tropical rain band tornadoes remains high! A Tornado
Watch is in effect for all of east central Florida until midnight
tonight.

Residents and visitors to east central Florida are urged to remain
informed this evening and overnight tonight. Travel is not recommended
and persons should remain indoors if at all possible. REMAIN IN YOUR
SAFE SHELTER UNTIL CONDITIONS ABATE!! DO NOT VENTURE OUTSIDE!! DOING SO
COULD RESULT IN SERIOUS INJURY OR DEATH FROM FLYING DEBRIS!!


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

* WIND:
Potential impacts from the main wind event are now unfolding across
the area. Remain well sheltered from life-threatening wind having
possible extensive impacts. These impacts include:
    - Considerable roof damage to sturdy buildings, with some having
      window, door, and garage door failures leading to structural
      damage. Mobile homes severely damaged, with some destroyed.
      Damage accentuated by airborne projectiles. Locations may be
      uninhabitable for weeks.
    - Widespread downing and uprooting of trees with fences and roadway
      signs blown over, especially due to saturated ground conditions.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. Several bridges, causeways, and
      access routes impassable.
    - Large areas with power and communications outages.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
east central Florida. Remain well guarded against life-threatening
flood waters having additional extensive impacts. If realized,
these impacts include:
    - Extensive rainfall flooding may prompt numerous evacuations and
      rescues.
    - Rivers and tributaries may overflow their banks
      in many places with deep moving water. Small streams, creeks,
      canals, and ditches may become fast moving rivers. Flood control
      systems and barriers may become stressed.
    - Flood waters can enter numerous structures within multiple
      communities, some structures becoming uninhabitable.
    - Driving conditions will become very dangerous as flood waters
      may cover escape routes in numerous places. Streets and parking
      lots become rivers of raging water with underpasses submerged.
      Numerous road and bridge closures may occur with some weakened
      or washed out.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across EAST
CENTRAL FLORIDA. Remain well braced against a dangerous tornado event
having additional significant impacts. If realized, these impacts include:
    - The occurrence of tornadoes can hinder the execution
      of emergency plans during tropical events.
    - Several places may experience tornado damage with a few
      locations seeing considerable damage, power loss, and
      communications failures.
    - Locations could realize roofs torn off frame houses, mobile
      homes demolished, boxcars overturned, large trees snapped or
      uprooted, vehicles tumbled, and small boats tossed about.
      Dangerous projectiles can add to the toll.

* SURGE:
Prepare for locally hazardous surge having impacts from Flagler Beach
to Jupiter Inlet. These 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,
      piers, and other coastal structures.


PRECAUTIONARY/PREPAREDNESS ACTIONS
