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

At 4 AM CDT, Tropical Storm Ida continues to move north-northwestward
at 8 mph over southwestern Mississippi. Minimum central pressure has
increased to 990 mb, with tropical storm force winds extending outward
up to 150 miles.

Ida is expected to bring additional rainfall amounts of 5-10 inches,
with higher isolated rainfall amounts up to 15 inches over southeast
Mississippi, coastal Alabama and the western Florida Panhandle.
Meanwhile, 3-6 inches of additional rain is expected elsewhere during
this time. This is likely to result in flash, urban, small stream, and
river flooding over portions of our area.

The tornado threat will continue across southeastern Mississippi,
southwestern Alabama, and portions of the western Florida Panhandle as
the outer rainbands on the eastern side of Ida move across the area.
This tornado threat is expected to persist and expand across much of
the area today.

3-5 feet of coastal water rises above normally dry ground along the
beaches, sounds, and the shoreline of Mobile Bay will continue today
into tonight. 1-3 feet of water rise is possible further east into the
western Florida Panhandle. Surf heights today will remain between 9-11
feet along the coast of Alabama and between 7-9 feet along the coast of
the western Florida Panhandle. Overall, these swells are likely to cause
life-threatening surf, wave run up, and dangerous rip currents. Waves
and swells will remain elevated today and tonight, and potentially into
Tuesday as strong south to southwest winds persist over the marine areas.

Tropical storm force conditions, especially in frequent gusts, will
continue today over coastal Alabama, as well as over interior southeast
Mississippi and portions of southwest Alabama.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
southeast Mississippi, southwest Alabama, and the western Florida
Panhandle. Remain well guarded against life-threatening flood waters
having possible extensive impacts. If realized, these 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.

Potential impacts from the flooding rain are still unfolding across
south-central Alabama. Remain well guarded against dangerous flood
waters having possible limited to significant impacts.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across portions
of southeast Mississippi, far southwest Alabama, and the far western
Florida Panhandle. Remain well braced against a dangerous tornado
event having possible significant impacts. If realized, these 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.

Potential impacts from tornadoes are still unfolding across the
remainder of the area. Remain well braced against a tornado event
having possible limited impacts.

* SURGE:
Potential impacts from the main surge event are now unfolding across
coastal Alabama and adjoining Mobile Bay shoreline. Remain well away
from life-threatening surge having possible significant impacts. If
realized, these impacts 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.

Potential impacts from the main surge event are also now unfolding
across coastal sections of the western Florida Panhandle. Remain well
away from locally hazardous surge having possible limited impacts.

* WIND:
Potential impacts from the main wind event are now unfolding across
southeast Mississippi and far southwest Alabama. Remain well
sheltered from hazardous wind having possible limited impacts. If
realized, these 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.

Elsewhere across portions of interior southwest and south-central
Alabama and the western Florida Panhandle, little to no impact is
anticipated.

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

* EVACUATIONS:
Do not enter evacuated areas until officials have given the all clear
to return.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a
battery-powered radio, charged cell phone and flashlight handy.

During the peak of the storm be ready to move quickly. Keep your
shoes on and rain gear handy. Boots and athletic shoes offer the best
foot protection if you become unexpectedly exposed to the weather.

Keep your cell phone charged and in power-saving mode. If you lose
power, use it sparingly and mainly for personal emergencies and
check-ins.

Quickly move to the safest place within your shelter if it begins to
fail, preferably an interior room on the lowest floor as long as
flooding is not a concern.

If you are prone to flooding or in an area under a storm surge watch
or warning, be prepared for the possibility of a quick and dramatic
rise in water levels.

If a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.
