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

Alberto continues on a north-northeastward motion over the southeastern 
Gulf of Mexico this evening. The storm is forecast to strengthen and
make a northward to north-northwestward motion over the Gulf of Mexico
through Sunday night before approaching the north central Gulf coast on
Monday. Alberto is forecast to move into the western Florida panhandle 
late Monday afternoon or early Monday evening, then continue slowly
northward into south central Alabama through Monday night. There remains
some uncertainty on the eventual track, so residents from coastal
Alabama through the Florida panhandle should closely monitor the progress
of the storm. Alberto will have the potential to bring significant
rainfall amounts and flash flooding to the region, especially across
the western Florida panhandle and much of southwest and south central 
Alabama. Tropical storm force winds will likely impact coastal portions of
the region late Sunday into Monday. Storm surge inundation of 2 to 4 feet, 
possibly higher, is expected mainly Sunday night into Monday. Isolated
tornadoes will also be possible, particularly across south central Alabama
and the western Florida panhandle Sunday night into Monday night.

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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible 
significant impacts across southwest and south central Alabama and
the western Florida panhandle. Potential impacts include:
    - Moderate rainfall flooding may prompt several evacuations and 
      rescues.
    - Rivers and tributaries may quickly become swollen with swifter 
      currents and overspill their banks in a few places, especially 
      in usually vulnerable spots. Small streams, creeks, canals, and 
      ditches overflow.
    - Flood waters can enter some structures or weaken foundations. 
      Several places may experience expanded areas of rapid 
      inundation at underpasses, low-lying spots, and poor drainage 
      areas. Some streets and parking lots take on moving water as 
      storm drains and retention ponds overflow. Driving conditions 
      become hazardous. Some road and bridge closures.

Protect against locally hazardous rainfall flooding having possible 
limited impacts across southeast Mississippi. 

* SURGE:
Protect against life-threatening surge having possible significant 
impacts across coastal portions of Alabama and the western
Florida panhandle. 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.

Elsewhere across portions of southwest Alabama...northwest 
Florida...south central Alabama...and inland southeast Mississippi, 
little to no impact is anticipated.

* WIND:
Protect against dangerous wind having possible significant impacts 
across portions of southwest Alabama...northwest Florida...south 
central Alabama...and inland southeast Mississippi.. Potential 
impacts include:
    - Some damage to roofing and siding materials, along with damage 
      to porches, awnings, carports, and sheds. A few buildings 
      experiencing window, door, and garage door failures. Mobile 
      homes damaged, especially if unanchored. Unsecured lightweight 
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater 
      numbers in places where trees are shallow rooted. Several 
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban 
      or heavily wooded places.
    - Scattered power and communications outages, but more prevalent 
      in areas with above ground lines.

* TORNADOES:
Protect against a tornado event having possible limited impacts 
across portions of southwest Alabama...northwest Florida...
and south central Alabama. 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.

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.

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, in a valley, or near an already swollen river, plan to 
move to safe shelter on higher ground.

If you are a visitor, know the name of the county in which you are
located and where it is relative to current watches and warnings.
If staying at a hotel, ask the management staff about their 
onsite disaster plan. Listen for evacuation orders, especially 
pertaining to area visitors.

Closely monitor weather.gov, NOAA Weather Radio and local news 
outlets for official storm information. Listen for possible changes 
to the forecast.
