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

Hurricane Idalia made landfall this morning as a Major Hurricane
near Keaton Beach, Florida. As Idalia continues move away, Tropical
Storm Force conditions continue across West Central and Southwest
Florida.

The following are the primary hazards of concern with Idalia:

* Storm Surge - Areas across West Central and Southwest Florida should
expect surge levels to remain nearly steady through the day as an
onshore wind keeps water piled up along the coast.

* Wind - Tropical storm force winds remain possible as outer rain
bands from Idalia move across the region.

* Rainfall - Heavy rainfall remains possible, with area rivers rising
into action of flood stage. Minor inland flooding in low- lying areas
with poor drainage remains possible. A Flood Watch also remains in
effect.

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

* SURGE:
Potential impacts from the main surge event are now unfolding across
West Central and Southwest Florida. Remain well away from life-
threatening surge having additional 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.

* WIND:
Potential impacts from the main wind event are now unfolding across
West Central and Southwest Florida. Remain well sheltered from
dangerous wind having additional significant impacts. If realized,
these impacts include:
    - Some damage to roofing and siding materials, along with damage
      to porches, awnings, carports, and sheds. A few buildings
      experiencing window, door, and garage door failures. Mobile
      homes damaged, especially if unanchored. Unsecured lightweight
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater
      numbers in places where trees are shallow rooted. Several
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges, causeways, and access
      routes impassable.
    - Scattered power and communications outages, but more prevalent in
      areas with above ground lines.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
West Central and Southwest Florida. Remain well guarded against
dangerous flood waters having additional significant impacts. If
realized, these 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.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across West
Central and Southwest Florida. Remain well braced against a tornado
event having additional 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, 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 boats pulled
      from moorings.

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

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

* OTHER PREPAREDNESS INFORMATION:
Do not be a thrill seeker or risk your life for senseless photos or
videos.

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