SITUATION OVERVIEW
------------------
At 10:00 PM CDT, Hurricane Sally remains at Category 2 strength as
it drifts very slowly west-northwest across the north central Gulf of
Mexico. Sally is forecast to turn toward the north throughout the
day Tuesday, with the center likely reaching the southwest Alabama or
southeast Mississippi coast late Tuesday night or early Wednesday.
The primary threat with Sally will be very heavy rainfall and the
potential for life threatening inland and storm surge flooding.
Potentially historic flash flooding will be possible as the storm
maintains its slow motion as it crosses the coast and moves slowly
northeastward after landfall. 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 southwest Alabama and
the western Florida panhandle.
A Storm Surge Warning remains in effect for coastal Alabama and the
western Florida panhandle. Water levels are forecast to reach 6 to 9
feet above dry ground along the Mobile County coast, including Dauphin
Island, and in Mobile Bay. Water levels around 4 to 7 feet are expected
along the Baldwin County Gulf coast and around 2 to 4 feet farther east
along the western Florida panhandle. In addition, rough surf and
dangerous rip currents are expected along the beaches with dangerous
wave run up.
Hurricane force wind gusts are possible along coastal portions of
southwest Alabama as well as George County in southeast Mississippi.
Tropical Storm force winds are likely across the western Florida
panhandle, southeast Mississippi, and interior southwest and south-
central Alabama.
A few tornadoes are also possible across the western Florida panhandle,
southwest and south central Alabama and southeast Mississippi. This
threat should develop late tonight and persist through Wednesday.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across portions of southeast Mississippi,
southwest Alabama, portions of interior south central Alabama and
the western Florida panhandle. 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
extensive impacts across interior portions of southeast Mississippi,
and southwest and south central Alabama.
* SURGE:
Protect against life-threatening surge having possible extensive
impacts across the southwest Alabama coast, including Dauphin Island
and Mobile Bay. Potential impacts in this area include:
- Large areas of deep inundation with storm surge flooding
accentuated by battering waves. Structural damage to buildings,
with several washing away. Damage compounded by floating
debris. Locations may be uninhabitable for an extended period.
- Large sections of near-shore escape routes and secondary roads
washed out or severely flooded. Flood control systems and
barriers may become stressed.
- Severe beach erosion with significant dune loss.
- Major damage to marinas, docks, boardwalks, and piers. Many
small craft broken away from moorings, especially in
unprotected anchorages with some lifted onshore and stranded.
Also, protect against life-threatening surge having possible
significant impacts across the western Florida panhandle.
* WIND:
Protect against life-threatening wind having possible extensive
impacts across extreme southeast Mississippi and 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 significant
impacts across interior southeast Mississippi, interior southwest
Alabama, south central Alabama, and the western Florida panhandle.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across portions of southwest Alabama, the western Florida panhandle,
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.
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.
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.
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.
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.
