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

Hurricane Idalia is moving northward across the eastern Gulf of
Mexico this evening and will approach the Big Bend region of Florida
early Wednesday. It is then expected to move northeastward across
northern Florida and towards the Georgia and Carolinas coast by late
Wednesday into early Thursday.

The following are the primary hazards of concern with Idalia:

* Coastal Flooding/Surge - Higher than usual tides due to the
combination of surge from Idalia and the upcoming full moon could lead
to coastal flooding of 1 to 3 feet along coastal Collier and mainland
Monroe Counties. Other vulnerable coastal areas of southern Florida
could also experience minor coastal flooding, especially around the
times of high tide.

* Rainfall - The majority of the rainfall associated with the system
is forecast to fall through Wednesday. Additional rain amounts of 1 to
3 inches with localized higher amounts are possible. The highest
amounts are anticipated along the Gulf coast.

* Wind - Gusty southerly winds continue across South Florida. Tropical
storm force winds remain possible along the Collier County coast. The
remainder of South Florida could see winds gusts up to 35mph, with the
highest gusts likely during the day on Wednesday.

* Tornadoes - A low-end tornado threat is possible through Wednesday,
mainly across the lake Okeechobee region.

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

* WIND:
Potential impacts from the main wind event are now unfolding across
Coastal Collier County. Remain well sheltered from hazardous
wind having possible limited impacts. If realized, these impacts include:
    - Damage to porches, awnings, carports, sheds, and unanchored
      mobile homes. Unsecured lightweight objects blown about.
    - Many large tree limbs broken off. A few trees snapped or
      uprooted, but with greater numbers in places where trees are
      shallow rooted. Some fences and roadway signs blown over.
    - A few roads impassable from debris, particularly within urban
      or heavily wooded places. Hazardous driving conditions on
      bridges and other elevated roadways.
    - Scattered power and communications outages.

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

* SURGE:
Potential impacts from the main surge event are now unfolding across
Coastal Collier and Mainland Monroe counties. Remain well away from
locally hazardous surge having possible limited impacts. If realized,
these impacts 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,
      and piers. A few small craft broken away from moorings.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
South Florida. Remain well guarded against locally hazardous flood
waters having additional limited impacts. If realized, these impacts include:
    - Localized rainfall flooding may prompt a few evacuations.
    - Ditches and canals may quickly rise with swift currents.
    - Flood waters can enter a few structures, especially in usually
      vulnerable spots. A few places where rapid ponding of water
      occurs at underpasses, low-lying spots, and poor drainage
      areas. Several storm drains and retention ponds become
      near-full and begin to overflow. Some brief road and bridge
      closures.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across the Lake
Okeechobee region. 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
----------------------------------

* 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.

Keep your cell phone charged and in power-saving mode. If you lose
power, use it sparingly and mainly for personal emergencies and
check-ins.

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