SITUATION OVERVIEW

Tropical Storm Bertha made landfall near the Biloxi Wildlife

Coastal flooding has been observed at the Shell Beach and Waveland
observation stations and additional minor to moderate coastal flooding
upwards of 2 to 3 feet is expected during the high tide cycle for
portions of coastal Louisiana and Mississippi through Thursday
morning.

Light rainfall is occurring with this storm over land areas though
additional heavier rainfall will be possible through Thursday for
coastal areas of Mississippi and southeast Louisiana. The threat of
excessive rainfall has decreased across all of southeast Louisiana and
south Mississippi.

All Tropical Storm Watches have been discontinued. A Tropical Storm
Warning remains in effect from the Plaquemines/St. Bernard Parish
line to Morgan City. No changes to Coastal Flood Warnings and Advisories have
been changed with this advisory package.

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

* WIND:
Potential impacts from the main wind event are now unfolding across
lower portions of the southeast Louisiana coastal parishes. Remain well
sheltered from hazardous wind having possible limited impacts.
If realized, these 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.

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

* SURGE:
Potential limited impacts from the main surge event are now unfolding
across portion of Coastal Southeast Louisiana and Coastal Mississippi.
These impacts include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots, or in areas
      farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots 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, boardwalks,
      and piers. A few small craft broken away from moorings.

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