SITUATION OVERVIEW
------------------

* OVERVIEW...At 400 AM CDT, Sub-Tropical Storm Alberto was moving
north-northeast near 7 mph off the coast of the Yucatan Peninsula. The
system is expected to continue moving north-northeast at a faster
speed later today, followed by a turn to the northwest on Sunday.
Tropical impacts should begin to be felt across Southeast Louisiana
and Southern Mississippi by late Sunday and Sunday night and persist
through Tuesday morning.

The primary impact will be heavy rainfall that could produce inland
flooding. Secondary impacts will be storm surge, tornadoes, and
tropical storm force winds.

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

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across portions of the Mississippi coast and extreme
southeast Louisiana. 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.

* WIND:
Prepare for hazardous wind having possible limited impacts across
Southeast Louisiana and South Mississippi. Potential impacts 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.

* SURGE:
Prepare for life-threatening surge having possible significant
impacts across the immediate coast of Mississippi and also
for east facing shores outside of the hurricane protection system
in far Southeast Louisiana. 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.
