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

Dangerous, life-threatening conditions are expected over the next 6 to
12 hours! The center of Hurricane Irma is expected to move north
northwest and remain very near Okeechobee, Osceola, Orange, and Lake
counties!

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 82 mph at the St. Lucie Power
Plant, 73 mph at the Fort Pierce Airport, 66 mph at Jensen Beach, 57
mph in Melbourne, and 56 mph at New Smyrna Beach.

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 10 inches have been recorded over much of the area with
isolated amounts up to 15 inches in St. Lucie County. An additional 6
to 10 inches of rain 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. NOW IS THE TIME
TO REMAIN IN YOUR SAFE SHELTER!

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.
    - Many large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - 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
----------------------------------

* EVACUATIONS:

If you are prone to flooding or in an area under a storm surge
warning, be prepared for the possibility of a quick and dramatic
rise in water levels.
