This Hazardous Weather Outlook is for portions of central
Louisiana, south central Louisiana, southwest Louisiana, west
central Louisiana, and southeast Texas.

.DAY ONE...This Afternoon and Tonight
Isolated, generally light, showers will continue to move from west
to east across the area as a weak boundary moves into and stalls
over the area. Rainfall totals of a quarter to a half inch can be
expected through tonight.

Dense marine fog will move inland across coastal parishes and
counties beginning shortly after sunset tonight. While the
northward extent of the fog is expected to be more limited tonight
than over the previous few days, visibilities of less than a mile
in the immediate vicinity of the coast will likely linger through
at least midday Sunday.

.DAYS TWO THROUGH SEVEN...Sunday through Friday
Isolated, mainly light showers will be possible Sunday morning as
a warm front lifts north of the area. Precipitation is expected to
come to an end by early afternoon.

Dense marine fog will continue to impact coastal parishes and
counties until around midday before beginning to dissipate.

A slow moving cold front will approach the area late Tuesday
before stalling across east Texas. This will result in scattered
to numerous showers and thunderstorms Tuesday evening through
Thursday with isolated precipitation continuing through next
weekend. Some of these storms could be on the stronger side and
may produce heavy rainfall. Rainfall totals of two to two and
half inches are expected with locally higher amounts. This
rainfall will have the potential to result in localized flash
flooding Wednesday or Thursday.

.SPOTTER INFORMATION STATEMENT...
Spotter activation is not anticipated.

.DAY ONE...This Afternoon and Tonight
Patchy marine fog this afternoon will increase in coverage and

of less than a mile can be expected. A marine fog advisory is in
effect until noon Sunday.

may produce heavy rainfall.
