SITUATION OVERVIEW
------------------
Tropical Storm Idalia continues to strengthen in the Yucatan Channel
today. The storm is forecast to move into the southeast Gulf of Mexico
tonight into Tuesday. Idalia is forecast to keep strengthening over the
eastern Gulf as it moves closer to the west coast of Florida.
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 full moon could lead to coastal
flooding of 2 to 4 feet in coastal Collier county and 1 to 3 feet
along the coast of mainland Monroe County. 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 from this afternoon through Wednesday. The greatest
risk for flash flooding will be near the Gulf coast. Storm total
rain amounts of 2 to 3 inches with localized higher amounts. The
highest amounts are anticipated along the Gulf coast.
* Wind - Increasingly gusty winds are forecast Tuesday through Thursday,
particularly along the Gulf coast and adjacent coastal waters. A
reasonable worst case scenario would have tropical storm force winds
across Collier County between Monday night and Wednesday. Areas of
the East Coast and Atlantic waters could also see gusty winds up to
35 mph during the same time frame.
* Tornadoes - A low-end tornado threat is possible through early
Thursday as banding from the system moves ashore. The focus for
tornadic activity could be in the western half of southern Florida.
POTENTIAL IMPACTS
-----------------
* SURGE:
Protect against life-threatening surge having possible significant
impacts across coastal Collier County. Potential impacts in this area
include:
- Areas of inundation with storm surge flooding accentuated by
waves. Damage to several buildings, mainly near the coast.
- Sections of near-shore escape routes and secondary roads become
weakened or washed out, especially in usually vulnerable low
spots.
- Major beach erosion with heavy surf breaching dunes. Strong and
numerous rip currents.
- Moderate damage to marinas, docks, boardwalks, and piers.
Several small craft broken away from moorings, especially in
unprotected anchorages.
Also, protect against locally hazardous surge having possible limited
impacts across coastal portions of mainland Monroe County.
Elsewhere across South Florida, little to no impact is anticipated.
* FLOODING RAIN:
Protect against locally hazardous rainfall flooding having possible
limited impacts across South Florida. Potential 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.
* WIND:
Protect against hazardous wind having possible limited impacts across
Southwest Florida. Potential impacts in this area 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.
* TORNADOES:
Protect against a tornado event having possible limited impacts across
South Florida. Potential 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
----------------------------------
* EVACUATIONS:
Listen to local official 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:
Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Ensure you are in a
safe location before the onset of strong winds or possible flooding.
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.
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.
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.
Rapidly rising flood waters are deadly. If you are in a flood-prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, turn around don't drown!
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.
