SITUATION OVERVIEW
------------------
At 10:00 PM CDT, Tropical Storm Sally will move west-northwest into
the north central Gulf of Mexico on Monday then slow and turn northwest
then north on Tuesday while approaching the north central Gulf coast.
This system will bring an extended period of heavy rains with amounts
of 8 to 16 inches expected, with locally higher amounts up to 25 inches
across the western Florida panhandle, southeast Mississippi and portions
of southwest Alabama. This could be a historically significant flood event
for our region. Hurricane Force winds are possible along the
immediate coastlines of Alabama, and Tropical Storm Force winds are
likely across the western Florida panhandle, southeast Mississippi and
portions of southwest Alabama. A Storm Surge Warning is now in effect
for coastal Alabama where water levels of 3 to 5 feet above dry ground
are possible. Further to the east, a Coastal Flood Advisory is in
effect with water levels of 1 to 3 feet above dry ground expected along
the western Florida panhandle. A few tornadoes are also possible across
the western Florida panhandle, southwest Alabama and southeast
Mississippi. In addition, rough surf and dangerous rip currents are
expected along the beaches with dangerous wave run up likely.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across extreme southeast Mississippi and extreme
southwest Alabama. Potential impacts include:
- Extreme rainfall flooding may prompt numerous evacuations and
rescues.
- Rivers and tributaries may overwhelmingly overflow their banks
in many places with deep moving water. Small streams, creeks,
canals, and ditches may become raging rivers. In mountain
areas, deadly runoff may rage down valleys while increasing
susceptibility to rockslides and mudslides. Flood control
systems and barriers may become stressed.
- Flood waters can enter numerous structures within multiple
communities, some structures becoming uninhabitable or washed
away. Numerous places where flood waters may cover escape
routes. Streets and parking lots become rivers of raging water
with underpasses submerged. Driving conditions become very
dangerous. Numerous road and bridge closures with some weakened
or washed out.
Protect against life-threatening rainfall flooding having possible
significant to extensive impacts across interior southeast Mississippi,
interior southwest Alabama and portions of south central Alabama and
the western Florida panhandle.
* WIND:
Protect against life-threatening wind having possible extensive
impacts across extreme southeast Mississippi and extreme southwest
Alabama. Potential impacts in this area include:
- Considerable roof damage to sturdy buildings, with some having
window, door, and garage door failures leading to structural
damage. Mobile homes severely damaged, with some destroyed.
Damage accentuated by airborne projectiles. Locations may be
uninhabitable for weeks.
- Many large trees snapped or uprooted along with fences and
roadway signs blown over.
- Some roads impassable from large debris, and more within urban
or heavily wooded places.
- Large areas with power and communications outages.
Also, protect against dangerous wind having possible limited to
significant impacts across interior southeast Mississippi, interior
southwest Alabama, south central Alabama, and the western Florida
panhandle.
* SURGE:
Protect against 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, protect against locally hazardous surge having possible limited
impacts across coastal portions of the western Florida panhandle.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across portions of southwest Alabama...northwest Florida...south
central Alabama...and inland southeast Mississippi.. 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.
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 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.
If you are relocating to safe shelter, leave as early as possible.
Allow extra time to reach your destination. Many roads and bridges
will be closed once strong winds arrive. Check the latest weather
forecast before departing and drive with caution.
If heading to a community shelter, become familiar with the shelter
rules before arrival, especially if you have special needs or have
pets. Take essential items with you from your Emergency Supplies Kit.
Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.
Keep cell phones well charged. Cell phone chargers for automobiles
can be helpful, but be aware of your risk for deadly carbon monoxide
poisoning if your car is left idling in a garage or other poorly
ventilated area.
It is important to remain calm, informed, and focused during an
emergency. Be patient and helpful with those you encounter.
If you are a visitor, be sure to know the name of the city or town in
which you are staying and the name of the county or parish in which
it resides. Listen for these locations in local news updates. Pay
attention for instructions from local authorities.
Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the local authorities.
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 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, consider moving to a safer shelter before the onset of
strong winds or flooding.
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.
