SITUATION OVERVIEW
------------------
Tropical Storm Cristobal continues moving northward across the south-central
Gulf of Mexico early this morning. Cristobal is forecast to approach the
southeast Louisiana coast Sunday evening, and then move northwestward across
Louisiana on Monday.
Tropical Storm Force winds will be possible along the coastal sections
of Alabama, portions of interior southeast Mississippi, and portions of the
western Florida Panhandle from late Saturday night through early Monday
morning.
Coastal Flooding is possible along coastal Alabama and the western Florida
Panhandle with inundation of 1 to 3 feet Sunday through Monday
afternoon, especially around the time of high tide. This also includes all
area bays and sounds. High Surf is likely with breaker heights of 9 to 13 feet
developing Saturday and continuing through Monday morning.
Rainfall amounts between 3 and 6 inches are expected along and south of the
Interstate 10 corridor, with isolated higher amounts up to 10 inches possible,
especially across southern portions of Mobile and Baldwin counties and inland
sections of southeast Mississippi. This may lead to flash flooding, especially
in poor drainage and urban areas.
A few tornadoes will also be possible from Sunday through Monday morning
along and south of Interstate 10, including coastal Alabama and coastal
portions of the western Florida Panhandle.
Prepare now for potentially damaging winds, minor coastal flooding,
strong rip currents, periods of heavy rainfall, and a few tornadoes
across locations within the Tropical Storm Warning area.
POTENTIAL IMPACTS
-----------------
* WIND:
Protect against hazardous wind having possible limited impacts across
portions of interior southeast Mississippi, coastal Alabama, and portions
of the western Florida Panhandle. Potential impacts in this area include:
- Damage to porches, awnings, carports, sheds, and unanchored
mobile homes. Unsecured lightweight objects blown about.
- Many large tree limbs broken off. A few trees snapped or
uprooted, but with greater numbers in places where trees are
shallow rooted. Some fences and roadway signs blown over.
- A few roads impassable from debris, particularly within urban
or heavily wooded places. Hazardous driving conditions on
bridges and other elevated roadways.
- Scattered power and communications outages.
Elsewhere across portions of southwest Alabama...northwest
Florida...south central Alabama...and inland southeast Mississippi.,
little to no impact is anticipated.
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across interior southeast Mississippi and coastal
Alabama. 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, canals, and ditches may
become dangerous rivers. In mountain areas, destructive runoff
may run quickly down valleys while increasing susceptibility to
rockslides and mudslides. 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 remainder of southwest Alabama, northwest
Florida, and south central Alabama.
* SURGE:
Protect against locally hazardous surge having possible limited
impacts across coastal Alabama and coastal portions of the western
Florida Panhandle, including all local bays and sounds. 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.
Elsewhere across portions of southwest Alabama...northwest
Florida...south central Alabama...and inland southeast Mississippi.,
little to no impact is anticipated.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across interior southeast Mississippi, coastal 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.
* OTHER COASTAL HAZARDS:
There will also be the continued threat for life threatening rip currents,
high surf, and coastal erosion along area beaches.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Listen to local official for recommended preparedness actions, including
possible evacuation. If ordered to evacuate, do so immediately.
* 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 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.
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.
