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

* Hurricane Ian has made landfall in southwest Florida at Cayo Costa
this afternoon and will continue to move inland across central Florida
the remainder of tonight. Hazardous conditions extend well away from
the center of the system. The following hazardous conditions can be
expected for South Florida:

* Peak storm surge values of 4 to 6 feet are expected particularly in
surge prone areas between Bonita Beach to Chokoloskee. Peak storm
surge values of 2 to 4 feet are the main concern from Chokoloskee to
East Cape Sable and 1 to 3 feet from East Cape Sable to Card Sound
Road along Florida Bay. The storm surge threat is ongoing, 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.

* Some residual flooding will be possible across portions of Collier,
Glades and Hendry counties due to earlier rainfall.

* Tornadoes embedded in showers and thunderstorms within the outer
rainbands associated with the system have been observed yesterday and
last night. Isolated tornadoes will be possible through Thursday
morning.

* Hazardous marine, beach, and surf conditions are ongoing. *

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

* SURGE:
Potential impacts from the main surge event are now unfolding across
Southwest Florida. Remain well away from life-threatening
surge having possible significant impacts. If
realized, these impacts include:
    - Areas of inundation with storm surge flooding accentuated by
      waves. Damage to several buildings, mainly near the coast.
    - Sections of near-shore escape routes and secondary roads become
      weakened or washed out, especially in usually vulnerable low
      spots.
    - Major beach erosion with heavy surf breaching dunes. Strong and
      numerous rip currents.
    - Moderate damage to marinas, docks, boardwalks, and piers.
      Several small craft broken away from moorings, especially in
      unprotected anchorages.

Potential impacts from the main surge event are also now unfolding
across the remainder of South Florida. Remain well away from locally
hazardous surge having possible limited impacts.

Elsewhere across South Florida, little to no impact is anticipated.

* WIND:
Potential impacts from the main wind event are now unfolding across
the northern half of South Florida. 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.

Potential impacts from the main wind event are also now unfolding
across the southern half of South Florida. Remain well sheltered from
dangerous wind having possible limited to
significant impacts.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
northern portions of South Florida. Remain well guarded against dangerous
flood waters having possible significant impacts.
If realized, these 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.

Potential impacts from the flooding rain are still unfolding across
southern portions of South Florida. Remain well guarded against locally
hazardous flood waters having possible limited
impacts.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across eastern portions of South Florida.
 Remain well braced against a tornado event
having possible limited impacts. If realized,
these 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.

Elsewhere across South Florida, little to no impact is anticipated.

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

* EVACUATIONS:

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

rise in water levels.
