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

At 4:00 PM CDT, Tropical Storm Sally located just south of Naples, Florida
will turn to the west-northwest tonight then move over the north central
Gulf Sunday night and Monday.  Sally is forecast to move to near the mouth
of the Mississippi River Monday night then slowly northward into southeast
Mississippi on Wednesday.  This system will bring an extended period of heavy
rain as rainfall amounts of 6 to 12 inches with locally higher amounts of 18
inches are possible across the western Florida panhandle, extreme southwest
Alabama and extreme southeast Mississippi. There is the potential for
hurricane force winds over coastal Alabama with a potential for tropical storm
force winds over coastal Alabama and the western Florida panhandle.  A Storm
Surge Watch is in effect for coastal Alabama where water levels of 2 to 4 feet
above dry ground are possible.  Further to the east, minor coastal flooding
with water levels of 1 to 3 feet above dry ground is possible along the
western Florida panhandle. A few tornadoes are also possible mainly across the
western Florida panhandle, extreme southwestern Alabama and extreme southeast
Mississippi.

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

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across extreme southeast Mississippi, extreme southwestern 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.

Prepare for locally hazardous rainfall flooding having possible
limited impacts across interior southeast Mississippi, interior
southwest Alabama and portions of south central Alabama.

* WIND:
Prepare for dangerous wind having possible significant impacts across
extreme southeast Mississippi and extreme southwest 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.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines.

Also, prepare for hazardous wind having possible limited impacts
across interior southeast Mississippi, interior southwest Alabama, the
western Florida panhandle and portions of south central Alabama.

* SURGE:
Prepare for life-threatening surge having possible significant
impacts across coastal Alabama. 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, prepare for locally hazardous surge having possible limited
impacts across coastal portions of the western Florida panhandle.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across extreme
southeast Mississippi, extreme southwestern Alabama, the western Florida
panhandle and extreme 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.

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

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

* EVACUATIONS:
Listen to local official for recommended preparedness actions, including
possible evacuation. If ordered to evacuate, do so immediately.

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.

Let others know where you are going prior to departure. Secure loose
items and pets in the car, and avoid distracted driving.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.

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 in a place that is vulnerable to high wind, such as near large
trees, a manufactured home, upper floors of a high-rise building, or
on a boat, plan to move to safe shelter.

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.

Always heed the advice of local officials and comply with orders that
are issued. Do not needlessly jeopardize your life or the lives of
others.

When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.

Be sure to let friends and family members know of your intentions for
weathering the storm and your whereabouts. Have someone located away
from the threatened area serve as your point of contact. Share vital
contact information with others. Keep cell phones handy and charged.

Check on those who may not be fully aware of the situation or who are
unable to make personal preparations.

If you are a visitor, know the name of the county or parish 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.

There is a threat from tornadoes with this storm. Have multiple ways
to receive Tornado Warnings. Be ready to shelter quickly.
