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

Hurricane Ian is currently moving north to northeast and will
slowly approach the Gulf coast of Florida today. Regardless of exact
landfall location, hazardous conditions will extend well away from the
center of the system. The following hazardous conditions can be
expected for South Florida:

* Peak storm surge values of 6 to 10 feet are expected particularly in
surge prone areas between Bonita Beach to Chokoloskee. Peak storm
surge values of 4 to 7 feet are the main concern from Chokoloskee to
East Cape Sable and 2 to 4 feet from East Cape Sable to Card Sound
Road along Florida Bay. The peak storm surge concern will be today and
tonight. Due to slow motion of the system, surge will be slow to
subside and may impact the region through late week. This could lead
to significant and life- threatening storm surge flooding particularly
along coastal Collier County.

* Multiple rounds of heavy rainfall associated with rainbands may lead
to flooding across all of South Florida. Additional rainfall amounts
of 2 to 4 inches with isolated amounts up to 8 inches are possible,
bringing storm totals to 6 to 8 inches with isolated amounts up to 12
inches. Flash-flooding will be possible in this environment.

* Tornadoes embedded in showers and thunderstorms within the outer
rainbands will continue to be possible today.

* Hazardous marine and beach conditions are expected. Dangerous surf
conditions are expected along the Gulf coast.

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

* WIND:
Potential impacts from the main wind event are now unfolding across
portions of Southwest Florida and areas near Lake Okeechobee. Remain
well sheltered from life-threatening wind having possible extensive
impacts. If realized, 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.

Also, protect against hazardous wind having possible significant
impacts across portions of Palm Beach County. Elsewhere across South
Florida limited impacts are possible mostly associated with the
possibility of seeing gusts to tropical storm force.

* SURGE:
Potential impacts from the main surge event are now unfolding across
southwest Florida coastline. Remain well away from life-threatening
surge having possible devastating impacts. If realized, these impacts
include:
    - Widespread deep inundation, with storm surge flooding greatly
      accentuated by powerful battering waves. Structural damage to
      buildings, with many washing away. Damage greatly compounded
      from considerable floating debris. Locations may be
      uninhabitable for an extended period.
    - Near-shore escape routes and secondary roads washed out or
      severely flooded. Flood control systems and barriers may become
      stressed.
    - Extreme beach erosion. New shoreline cuts possible.
    - Massive damage to marinas, docks, boardwalks, and piers.
      Numerous small craft broken away from moorings with many lifted
      onshore and stranded.

Potential impacts from the main surge event are also now unfolding
across portions of coastal Mainland Monroe County. Remain well away
from life-threatening surge having possible significant to extensive
impacts.

Potential impacts from the main surge event are also now unfolding
across coastal portions of Florida Bay and extreme southern Miami-Dade
County. Remain well away from locally hazardous surge having possible limited
impacts.

Minor coastal flooding may be observed across portions of the east
coast.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
South Florida. Remain well guarded against life-threatening flood
waters having possible extensive impacts. If realized, these impacts
include:
    - Major rainfall flooding may prompt many evacuations and rescues.
    - Ditches and canals may rapidly overflow their banks in multiple
      places. Flood control systems and barriers may become stressed.
    - Flood waters can enter many structures within multiple
      communities, some structures becoming uninhabitable or washed
      away. Many places where flood waters may cover escape routes.
      Streets, parking lots and underpasses become submerged. Driving
      conditions become dangerous. Many road and bridge closures with
      some weakened or washed out.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across South
Florida. Remain well braced against a dangerous tornado event having
additional significant impacts. If realized, these impacts include:
    - The occurrence of scattered tornadoes can hinder the execution
      of emergency plans during tropical events.
    - Several places may experience tornado damage with a few spots
      of 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.

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

* EVACUATIONS:
Do not enter evacuated areas until officials
have given the all clear to return.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a
battery-powered radio, charged cell phone and flashlight handy.

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

If a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.
