This Hazardous Weather Outlook is for portions of Southeast
Louisiana...South Mississippi and the adjacent coastal waters.

.DAY ONE...Tonight

Isolated thunderstorms over the area will come to an end by late
this evening. Occasional lightning strikes and brief downpours can
be expected from these isolated thunderstorms.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Scattered thunderstorms are possible each day...mainly in the
afternoon hours. Widespread severe weather is not expected
however an isolated strong to severe storm is possible. Main
concern will be gusty winds, brief heavy rain, and occasional
lightning. Waterspouts and tropical funnels will be possible in
marine areas as the storms develop in the morning hours.

From Wednesday onward into the Memorial Day Weekend, the overall
weather pattern would favor the potential for heavy rainfall and
possible flood threat due to an abundance of tropical moisture.
There is a high degree of uncertainty on location and timing at
this time. All interests should pay close attention to the
weather developments throughout the week.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated through Wednesday, but may
be needed for flood monitoring later in the week.
