SITUATION OVERVIEW
------------------
Tropical Storm Zeta is currently over the Yucatan Peninsula, and is
forecast to move into the Gulf of Mexico later today and re-strengthen
into a hurricane. Zeta is expected to make landfall along the northern
Gulf Coast by Wednesday evening and move quickly across Central
Alabama Wednesday night. A swath of 40 to 50 mph wind gusts is
expected to occur along and to the right of Zeta's track, roughly south
of Interstate 59, with gusts of 50 to 60 mph possible across south-
central Alabama. Rainfall amounts of 2 to 4 inches are expected with
locally higher amounts, which may cause localized flash flooding. There
is also a low threat of a brief tornado Wednesday night across
southern and southeastern portions of Central Alabama.
POTENTIAL IMPACTS
-----------------
* WIND:
Prepare for dangerous wind having possible significant impacts across
South-Central 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. A few bridges, causeways, and access
routes impassable.
- Scattered power and communications outages, but more prevalent
in areas with above ground lines.
Also, prepare for hazardous wind having possible limited impacts
as far north as Interstate 59.
* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts south of Interstate 59 and north of Interstate 85. 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,
arroyos, 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.
* TORNADOES:
Prepare for a tornado event having possible limited impacts across
south-central and southeastern portions of 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 boats pulled
from moorings.
Elsewhere across Central Alabama, little to no tornado impact is
anticipated.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* 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.
Closely monitor weather.gov, NOAA Weather Radio and local news outlets
for official storm information. Listen for possible changes to the
forecast.
