Key Messages:

1. Life-threatening storm surge is expected near and east of where
Delta makes landfall this evening, and a Storm Surge Warning is in
effect from High Island, Texas, to Ocean Springs, Mississippi. The
highest inundation of 7 to 11 feet is expected somewhere between
Rockefeller Wildlife Refuge and Morgan City, Louisiana. Residents
in the warning area should promptly follow advice given by local
officials. The storm surge risk remains high despite the forecast
decrease in intensity before landfall since Delta is a relatively
large hurricane.

2. Hurricane-force winds are expected this afternoon and evening
somewhere within the Hurricane Warning area between High Island,
Texas, and Morgan City, Louisiana.  Hurricane force winds will also
spread inland across portions of southern Louisiana near the path of
Delta's center this evening and tonight.

3. Heavy rainfall will lead to significant flash flooding and minor
to major river flooding in parts of Louisiana today and Saturday.
Additional flooding is expected across portions of the central Gulf
Coast into the Lower Mississippi Valley.
