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 to a major hurricane. Watches
remain in effect for West Central and Southwest Florida and adjacent
coastal waters.
The following are the primary hazards of concern with Idalia:
* 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.
* 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.
* 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
-----------------
* WIND:
Prepare for life-threatening wind having possible devastating impacts
across the Nature Coast and Tampa Bay region. 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.
Also, prepare for life-threatening wind having possible limited to
extensive impacts across Southwest Florida.
* SURGE:
Prepare for life-threatening surge having possible devastating
impacts along the Nature Coast. 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.
Also, prepare for life-threatening surge having possible significant
to extensive impacts across Tampa Bay and Southwest Florida.
* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts across the Nature Coast. 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.
Prepare for dangerous rainfall flooding having possible limited to
significant impacts across Tampa Bay and Southwest Florida.
* TORNADOES:
Prepare for a dangerous tornado event having possible significant
impacts across West-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 boats tossed about. Dangerous
projectiles can add to the toll.
Prepare for a tornado event having possible limited impacts across
Southwest Florida.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Listen to local officials for recommended preparedness actions,
including possible evacuation. If ordered to evacuate, do so
immediately.
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.
* OTHER PREPAREDNESS INFORMATION:
When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.
If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low-lying or poor
drainage area, or near an already swollen river, plan to move to safe
shelter on higher ground.
Always heed the advice of local officials and comply with orders that
are issued. Do not needlessly jeopardize your life or the lives of
others.
