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

OVERVIEW...At 1000 AM CDT, Sub-Tropical Storm Alberto was moving
north at 10 mph near the western tip of Cuba. The system is expected
to move into the Gulf of Mexico by this afternoon and then turn to the
north- northwest toward the central Gulf coast by tomorrow. Tropical
storm impacts should begin to be felt across portions of Southeast
Louisiana mainly east of Interstate 55 and across coastal Mississippi
by Sunday night.

The primary impact will be heavy rainfall that could produce inland
flooding. Rainfall should range from 2 to 4 inches across southeast
Louisiana east of Interstate 55 to 4 to 6 inches across coastal
Mississippi. Secondary impacts will be storm surge and tropical storm
force winds. Storm surge should range from 1 to 3 feet along the
shores of Lake Pontchartrain to 2 to 4 feet along the Mississippi
coast and east facing shores of southeast Louisiana outside of the
hurricane protection system. Tropical storm force winds are most
likely to be felt along portions of the Mississippi coast.

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

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across portions of coastal Mississippi from Gulfport to the
Mississippi and Alabama state line. 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 portions of coastal Mississippi west of Gulfport
and across portions of Southeast Louisiana mainly to the east of
Interstate 55.

* SURGE:
Prepare for life-threatening surge having possible significant
impacts across coastal Mississippi and east facing shores of
Southeast Louisiana outside of the hurricane protection system
between the mouth of the Mississippi River and the Rigolets. 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, prepare for locally hazardous surge having possible limited
impacts along the shores of Lake Pontchartrain.

Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.

* WIND:
Prepare for hazardous wind having possible limited impacts across
Southeast Louisiana mainly east of Interstate 55 and across
coastal 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.

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.

If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low-lying or poor
drainage area, in a valley, or near an already swollen river, plan to
move to safe shelter on higher ground.

When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.

If you are a visitor, know the name of the county or parish in which
you are located and where it is relative to current watches and
warnings. If staying at a hotel, ask the management staff about their
onsite disaster plan. Listen for evacuation orders, especially
pertaining to area visitors.

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

NEXT UPDATE
-----------

The next local statement will be issued by the National Weather
Service in New Orleans LA around 2 PM CDT, or sooner if conditions
warrant.
