At 4:00 AM CDT, Tropical Storm Marco has advanced north-northwestward
out of the Yucatan Channel and is expected to strengthen to a hurricane
while it continues on this general movement across the Gulf through
Sunday night towards southeast Louisiana. Marco is forecast to move
into southeast Louisiana on Monday at or near hurricane strength, then
is expected to rapidly weaken and gradually turn to the west.

POTENTIAL IMPACTS
-----------------

* SURGE:
Prepare for 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.
    - Moderate 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.

Elsewhere across portions of the western Florida panhandle, little to
no impact is anticipated.

* WIND:
Prepare for hazardous wind having possible limited impacts across
extreme southeast Mississippi and extreme southwest Alabama. 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 inland southwest Alabama...the
western Florida panhandle...south central Alabama...and inland
southeast Mississippi, little to no impact is anticipated.

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across southeast Mississippi, southwest Alabama, and the
western Florida panhandle. 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, 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.

Prepare for locally hazardous rainfall flooding having possible
limited impacts across south central Alabama.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across
extreme southeast Mississippi and extreme southwest 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 small boats
      pulled from moorings.

Elsewhere across portions of inland southwest Alabama...the
western Florida panhandle...south central Alabama...and inland
southeast Mississippi, little to no impact is anticipated.

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.

* 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.

Check on those who may not be fully aware of the situation or who are
unable to make personal preparations.

Closely monitor weather.gov, NOAA Weather Radio and local news outlets
for official storm information. Listen for possible changes to the
forecast.
