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

The center of Hurricane Idalia is located around 195 miles southwest of
Tampa late this afternoon. Idalia currently has maximum sustained winds
of 100 mph and is moving north at 16 mph. Idalia will continue to move
north through tonight, with an eventual turn to the north-northeast into
Wednesday. Idalia is forecast to cross the Florida Gulf coast on Wednesday
as a major hurricane. Local preparations should be nearing completion
ahead of local tropical storm conditions by tonight and into Wednesday.

A Tropical Storm Warning remains in effect for Lake, Osceola, Orange,
Seminole, Volusia, and Brevard counties. For the Atlantic waters, a
Tropical Storm Warning remains in effect north of Sebastian Inlet.

Showers and squalls associated with outer rain bands from Idalia
have reached east central Florida late this afternoon. Conditions
will deteriorate further tonight and Wednesday as Idalia accelerates
north-northeastward across the eastern Gulf of Mexico. The possibility
of strong to damaging wind gusts in squalls will increase as tropical
storm force winds extend well east of the storm's center. Based on the
current forecast track, Idalia will make its closest pass to east-
central Florida late tonight and early Wednesday morning, continuing
northeastward during the day on Wednesday. Even as Idalia moves north
of the area on Wednesday, conditions will remain quite windy. A Wind
Advisory may be needed for portions of the area through Wednesday
evening.

While the heaviest rainfall from Idalia is forecast to fall along the
Gulf Coast and western Florida Peninsula, gusty squalls will be
capable of torrential downpours, through tonight and
continuing into Wednesday. Around one to one and one-half inches of
rain is forecast for coastal areas and Okeechobee County from tonight
through Wednesday night, and two to four inches is forecast west of
I-95 from Brevard and Osceola Counties northward, with locally higher
amounts possible. Locations in closer proximity to the center of
Idalia, generally along and west of Interstate Four in east-central
Florida, may receive higher rainfall totals.

In addition to strong wind gusts, a threat for tornadoes is forecast
tonight and continuing into the day on Wednesday. The risk for tornados
will increase during the late evening and overnight hours as wind shear
increases in association with Hurricane Idalia. Ensure you have multiple
ways to receive warnings such as a charged cell phone or weather radio.

Incoming Atlantic swell from Major Hurricane Franklin, combined with
winds from Idalia, will lead to high seas, rough surf, an increase in
life-threatening rip currents, and beach erosion during high tides
through Wednesday.

Do not let your guard down. Impacts from Idalia will be felt far from
the center of the storm.

Continue to monitor the latest forecasts from the National Hurricane
Center and National Weather Service in Melbourne, Florida.

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

* WIND:
Protect against hazardous wind having possible limited impacts across
East Central Florida. Potential 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.

* TORNADOES:
Protect against a dangerous tornado event having possible significant
impacts across east central Florida. Potential 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.

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across east central Florida. Potential
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.

* SURGE:
Direct surge impacts from Idalia are not currently anticipated at
this time. However, larger swells and surf combined with Hurricane
Franklin will bring a threat for minor coastal flooding and beach
erosion. Locations more vulnerable to coastal flooding and beach
erosion, such as portions of the Volusia and Brevard county coast,
should stay updated on the latest information.

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

* EVACUATIONS:
Listen to local official for recommended actions.

* OTHER PREPAREDNESS INFORMATION:

Keep cell phones well charged. Cell phone chargers for automobiles
can be helpful, but be aware of your risk for deadly carbon monoxide
poisoning if your car is left idling in a garage or other poorly
ventilated area.

If you are a visitor, be sure to know the name of the city or town in
which you are staying and the name of the county or parish in which
it resides. Listen for these locations in local news updates. Pay
attention for instructions from local authorities.

If a Tornado Warning is issued for your area, be ready to shelter
quickly, preferably away from windows and in an interior room not
prone to flooding. If driving, scan the roadside for quick shelter
options.

Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
