SITUATION OVERVIEW
------------------
Tropical Storm Idalia continues to intensify off of the Yucatan
Coast this morning. Idalia is forecast to move north and eventually
northeast across the eastern Gulf of Mexico, making its way towards
the Florida peninsula and intensifying into a major hurricane. Watches
and Warnings remain in effect for West Central and Southwest Florida
and adjacent coastal waters.
The following are the primary hazards of concern with Idalia:
* Storm Surge - Areas across the Nature Coast are forecast to see
extreme life-threatening levels of storm surge, with life- threatening
surge also possible across west-central Florida. The main period of
coastal flooding looks to occur Tuesday afternoon through early
Thursday.
* Wind - Winds will increase Tuesday and remain gusty even after the
storm passes into Thursday. Hurricane force winds are possible across
much of the area and should be what residents prepare for, with
tropical storm force winds possible across the southern zones.
* Rainfall - The majority of the rainfall associated with the system
is forecast to fall Tuesday and Wednesday. A slight to moderate risk
for flooding is possible, mainly along the coast and across the
northern zones. Rainfall totals of 4 to 8 inches with locally higher
amounts up to 12 inches is possible.
POTENTIAL IMPACTS
-----------------
* SURGE:
Protect against life-threatening surge having possible devastating
impacts across west central and southwest Florida. Potential impacts in
this area 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:
Protect against life-threatening wind having possible devastating
impacts across west central and southwest Florida. Potential impacts in
this area include:
- Structural damage to sturdy buildings, some with complete roof
and wall failures. Complete destruction of mobile homes. Damage
greatly accentuated by large airborne projectiles. Locations
may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and
roadway signs blown over.
- Many roads impassable from large debris, and more within urban
or heavily wooded places. Many bridges, causeways, and access
routes impassable.
- Widespread power and communications outages.
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across west central and southwest Florida. Potential
impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, and ditches may
become dangerous rivers. 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 and parking lots become rivers of moving water with
underpasses submerged. Driving conditions become dangerous.
Many road and bridge closures with some weakened or washed out.
* TORNADOES:
Protect against a dangerous tornado event having possible significant
impacts across west central and southwest 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 boats tossed about. Dangerous
projectiles can add to the toll.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
WATCH/WARNING PHASE - Listen to local official for recommended
preparedness actions, including possible evacuation. If ordered to
evacuate, do so immediately.
WATCH/WARNING PHASE - For those not under evacuation orders, assess
the risk from wind, falling trees, and flooding at your location. If
you decide to move, relocate to a safer location nearby. If you do
not relocate, help keep roadways open for those under evacuation
orders.
WATCH/WARNING PHASE - If evacuating, leave with a destination in mind
and allow extra time to get there. Take your emergency supplies kit.
Gas up your vehicle ahead of time.
* OTHER PREPAREDNESS INFORMATION:
If you are relocating to safe shelter, leave as early as possible.
Allow extra time to reach your destination. Many roads and bridges
will be closed once strong winds arrive. Check the latest weather
forecast before departing and drive with caution.
If heading to a community shelter, become familiar with the shelter
rules before arrival, especially if you have special needs or have
pets. Take essential items with you from your Emergency Supplies Kit.
Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the local authorities.
