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

Not much change with Tropical Storm Sally overnight as
reconnaissance aircraft earlier reported little fluctuation in the
maximum sustained winds and minimum central pressure despite ongoing
persistent convection, especially on its eastern and northern sides.
Sally is still expected to undergo steady strengthening, becoming a
hurricane while slowing down in forward speed, on its west-
northwestward approach near the Mississippi River delta. Once Sally
does slow down, the storm is expected to take a more northward turn
towards the far eastern Louisiana/Mississippi coastline. Once Sally
advances inland, the storm is expected to take a more northeast turn
for Wednesday into Thursday. With Acadiana to remain on the western
side of the system, expect mainly a potential for minor impacts
where rainfall of up to 1 inch will be possible with locally higher
amounts, possible wind gusts up to near tropical storm strength and
minimal coastal inundation.

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

* FLOODING RAIN:
Protect against locally hazardous rainfall flooding having possible
limited impacts across eastern portions of Acadiana. Potential
impacts include:
    - Localized rainfall flooding may prompt a few evacuations.
    - Rivers and tributaries may quickly rise with swifter currents.
      Small streams, creeks, canals, and ditches may become swollen
      and overflow in spots.
    - Flood waters can enter a few structures, especially in usually
      vulnerable spots. A few places where rapid ponding of water
      occurs at underpasses, low-lying spots, and poor drainage
      areas. Several storm drains and retention ponds become
      near-full and begin to overflow. Some brief road and bridge
      closures.

Elsewhere across Southwest Louisiana and Southeast Texas, little to
no impact is anticipated.

* WIND:
Protect against hazardous wind having possible limited impacts across
eastern portions of Acadiana. 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 Southwest Louisiana and Southeast Texas, little to
no impact is anticipated.

* SURGE:
Protect against locally hazardous surge having possible limited
impacts across coastal portions of Iberia and St.Mary parishes.
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 along rivers and bayous that drain into the Gulf.
    - Sections of roads and parking lots near bodies of water may
      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, and piers.
      A few small craft broken away from moorings.

Elsewhere across Southwest Louisiana and Southeast Texas, 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.

* 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 heading to a community shelter, become familiar with the shelter
rules before arrival, especially if you have special needs or have
pets. Take essential items with you from your Emergency Supplies Kit.

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!

Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
