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

The track for Alberto continues to shift eastward. While the general
path of Alberto is agreed upon fairly well between models, the finer
details regarding landfall remain uncertain. Regardless of the
uncertainty in the last 12 or so hours of Alberto's track, the
threats posed remain unchanged. The greatest threat to the region is
for heavy rain and flash flooding. A Flash Flood Watch has been
issued starting early Sunday morning for the Panhandle and Big Bend,
southeast Alabama, and extreme southwest Georgia. Expected rain
amounts of 4 to 8" with isolated higher amounts are possible in this
area. Coastal flooding in storm surge is possible across the entire
Big Bend and Panhandle coast, with 2 to 4 feet inundation possible.
The greatest threat for storm surge impacts will be across the
western Big Bend and mouth of Apalachee Bay on Sunday, with a
continuing but lesser threat on Monday. Across the Panhandle, the
threat for storm surge will peak on Monday. The threat for tropical
storm force winds to impact the region has drawn near enough that an
upgrade from a watch to a Tropical Storm Warning was necessary.
Previous watches were upgraded to warnings, and a new Tropical Storm
Watch has been issued for Calhoun, Washington, Holmes, and northern
Walton counties in Florida. The probability of tropical storm force
winds has increased and spread further inland with the eastward
shift in the track. Isolated tornadoes remain possible across the
entire Tri-State region both Sunday and Monday.

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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across the eastern Panhandle of Florida and
southeast Alabama. 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,
      arroyos, 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 the Big Bend of Florida and southwest Georgia.

* SURGE:
Protect against life-threatening surge having possible significant
impacts across Franklin and Wakulla counties. 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 the eastern Big Bend and Panhandle of Florida.

* WIND:
Protect against dangerous wind having possible significant impacts
across the eastern Panhandle of Florida. Potential impacts in this
area 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. A few bridges, causeways, and access
      routes impassable.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines.

Also, protect against dangerous wind having possible limited impacts
across southeast Alabama and the western Big Bend of Florida.

Elsewhere across eastern Big Bend and south Georgia, little to no
impact is anticipated.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across southeast Alabama, southwest Georgia, and north 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, 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.
