SITUATION OVERVIEW
------------------
At 4 AM CDT, Extremely dangerous Hurricane Ida was located over
the north central Gulf of Mexico, moving northwest at 15 mph. On
the forecast track, the center of Ida will continue to progress
northwest, making landfall along the northern Gulf coast this
afternoon. Currently, hurricane-force winds extend outward up to
40 miles from the center and tropical-storm-force winds extend
outward up to 140 miles.
Ida will likely bring rainfall amounts of 5 to 10 inches, with
isolated higher amounts up to 15 inches, especially over southeast
Mississippi and southwest Alabama through Monday night. This is
likely to result in flash, urban, small stream, and river flooding
over portions of our area.
The tornado threat will begin to increase today across southeastern
Mississippi, southwestern Alabama, and portions of the western Florida
Panhandle as the outer rainbands on the east and northeast side of Ida
move into and across the area. This tornado threat will likely persist
and expand across much of the region tonight into Monday.
Depending on the exact track of Ida after landfall, tropical storm
force conditions, especially in frequent gusts, could occur over
interior southeast Mississippi and portions of southwest and coastal
Alabama.
Swells have begun to impact our portion of the Gulf Coast. 3 to 5
feet of coastal water rises above normally dry ground are expected
along the beaches, sounds, and the shoreline of Mobile Bay. 1 to 3
feet of water rise is possible further east into the western Florida
Panhandle. Surf heights will increase to be between 5-10 through this
evening. These swells are likely to cause life-threatening surf, wave
run up, and dangerous rip currents. Waves and swells are likely to
remain elevated into Monday and potentially Tuesday as strong south
to southwest winds persist over the marine areas.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across southeast Mississippi and portions of
southwest Alabama. 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.
Protect against dangerous rainfall flooding having possible limited
to significant impacts across the remaining portions of the local
area.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across portions of southwest Alabama...northwest Florida...south
central Alabama...and inland southeast Mississippi.. 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, chimneys
toppled, 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.
* WIND:
Protect against hazardous wind having possible limited impacts across
southeast Mississippi and far southwest Alabama. 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 portions of southwest Alabama...northwest
Florida...south central Alabama...and inland southeast Mississippi.,
little to no impact is anticipated.
* SURGE:
Protect against life-threatening surge having possible significant
impacts across coastal Alabama and adjoining Mobile Bay shoreline.
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 sections of the western Florida Panhandle.
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.
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:
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.
Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.
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.
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.
