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

Hurricane Sally was still located 140 miles southwest of Panama City,
with impacts continuing to extend well north of the center into the
Florida Panhandle and Big Bend. Sally will continue tracking west
northwest overnight, before turning more north and making landfall
along the northern Gulf coast Tuesday night. The greatest threat to
the area continues to be heavy rain, as Sally's forward speed slows.
Rainfall amounts of 4 to 8 inches with locally higher amounts are
possible across the Florida Panhandle and Western Big Bend into
Southeast Alabama, which could result in flash flooding through
Tuesday Night.

Additional impacts include tropical storm force winds, potential
tornadoes, and hazardous surf conditions.

Sustained tropical storm force winds continue over the Gulf of
Mexico waters. These tropical storm force winds are likely to
occasionally reach the immediate coast of the Florida Panhandle to
the west of Indian Pass through Tuesday, especially in heavier rain
bands. Minor storm surge flooding with 1 to 3 feet of inundation
above normally dry ground is expected across the Florida Panhandle
and Big Bend coast near the times of high tide. A few tornadoes will
be possible across the Florida Panhandle into Southeast Alabama.
High surf will continue to create very dangerous conditions at area
beaches, with life-threatening rip currents through mid-week.

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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across the Florida Panhandle and Western
Big Bend, Southeast Alabama, and portions of Southwest Georgia.
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, 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 Eastern Florida Big Bend.

* WIND:
Protect against hazardous wind having possible limited impacts across
the Florida Panhandle and Western Florida Big Bend into portions of
Southeast Alabama.
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.

Elsewhere across the Eastern Florida Big Bend, and Southwest Georgia,
little to no impact is anticipated.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across the Florida Panhandle and Western Florida Big Bend into
Southwest 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.

Elsewhere across the Eastern Florida Big Bend, and Southwest Georgia,
little to no impact is anticipated.

* SURGE:
Protect against locally hazardous surge having possible limited impacts
across the coastal areas of the Florida Panhandle and the Big Bend.
Potential impacts in this area include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots, or in areas
      farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots become overspread
      with surge water. Driving conditions dangerous in places where
      surge water covers the road.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly
      in usually vulnerable locations. Strong rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

* OTHER COASTAL HAZARDS:
A high risk of rip currents and high surf is likely through Tuesday.

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

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!

If a Tornado Warning is issued for your area, be ready to shelter
quickly, preferably away from windows and in an interior room not
prone to flooding. If driving, scan the roadside for quick shelter
options.

If you are a visitor, be sure to know the name of the city in which
you are staying and the name of the county in which it resides.
Listen for these locations in local news updates. Pay attention for
instructions from local authorities.

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.
