SITUATION OVERVIEW
------------------
As of 1:00 PM CDT, the center of Tropical Storm Sally will continue to
move very slowly north-northeast through south central Alabama. Life
threatening storm surge continues in surge prone areas along the
western Florida Panhandle. Damaging winds will continue across portions
of the western Florida panhandle and south central Alabama.
Historic and extremely dangerous flash flooding and river flooding will
continue through tonight due to total rainfall amounts of 20 to 30
inches, with isolated amounts of 35 inches along coastal Alabama and
the western Florida Panhandle. Farther north over interior portions of
southwest and south-central Alabama, rainfall totals of 8 to 16 inches
with locally higher amounts between 20 and 25 inches will be possible
through Thursday.
A Storm Surge Warning remains in effect for the western Florida Panhandle
with water levels of 3 to 5 feet, and Coastal Flood Advisory is now in
effect for portions of southwest Alabama. In addition, rough surf and
dangerous rip currents are expected along the beaches with dangerous wave
run up.
A few tornadoes are also possible across the western Florida Panhandle and
south-central Alabama today.
POTENTIAL IMPACTS
-----------------
* SURGE:
Protect against life-threatening surge having possible significant
impacts across the western Florida Panhandle. 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 southwest Alabama, mainly along the eastern shore of
Mobile Bay.
* WIND:
Protect against dangerous wind having possible significant impacts
across south central Alabama and the western Florida Panhandle.
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, protect against hazardous wind having possible limited impacts
across southwest Alabama.
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across coastal Alabama, the western Florida
Panhandle, and portions of south central 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
limited to extensive impacts across portions of inland southwest
Alabama.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across portions of south central Alabama and the western Florida
Panhandle. 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:
Do not enter evacuated areas until officials have given the all clear
to return.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a
battery-powered radio, charged cell phone and flashlight handy.
During the peak of the storm be ready to move quickly. Keep your
shoes on and rain gear handy. Boots and athletic shoes offer the best
foot protection if you become unexpectedly exposed to the weather.
Keep your cell phone charged and in power-saving mode. If you lose
power, use it sparingly and mainly for personal emergencies and
check-ins.
Be aware of your risk for deadly carbon monoxide poisoning. Make sure
generators are placed outside and in a well-ventilated area away from
where you are sheltering. Do not leave your car running in the garage.
Do not be a thrill seeker or risk your life for senseless photos or
videos.
Quickly move to the safest place within your shelter if it begins to
fail, preferably an interior room on the lowest floor as long as
flooding is not a concern.
If you are prone to flooding or in an area under a storm surge watch
or warning, be prepared for the possibility of a quick and dramatic
rise in water levels.
If a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.
