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

.DAY ONE...Today and Tonight

A marginal risk of severe thunderstorms exists for areas north of
the I-12 corridor in Southeast Louisiana and for all of Southwest
Mississippi today. The primary threat from any severe
thunderstorms will be strong damaging wind gusts. Any severe
thunderstorm activity should be isolated. All of the thunderstorms
that form today, severe or non-severe, could produce frequent
lightning strikes and locally heavy downpours.

Small craft advisory conditions may develop tonight over the open
Gulf waters. An east wind of 20 to 25 knots and increasing seas of
up to 10 feet are currently forecast for the Gulf waters tonight.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

The National Hurricane Center has a high chance of tropical
cyclone development during the next 2 days near the Yucatan
Peninsula and into the southern and central Gulf of Mexico. There
is still quite a bit of uncertainty in the evolution of this
system so please continue to follow the latest updates.

Depending on if a tropical system develops, east winds of 20 to
30 knots with higher gusts and waves of up to 14 feet may develop
over the open Gulf coastal waters Tuesday and Tuesday night. Winds
may turn to the south at 20 to 25 knots by Wednesday and remain
at these levels through Friday. These conditions could result in
the continuation of Small Craft Advisories for portions of the
coastal waters Tuesday through Friday.

If the tropical system forms, persistent east and southeast winds
of 20 to 25 knots combined with high offshore seas could increase
tide levels up to 2 feet above normal levels on east facing
shores Tuesday and Wednesday.

A period of heavy rainfall could occur across Southeast Louisiana
and Southern Mississippi. A marginal to slight risk of excessive
rainfall is currently forecast for the area on Tuesday and
Wednesday. Rainfall totals of 4 to 8 inches could occur between
Tuesday and Friday along the Louisiana and Mississippi coasts
including metro New Orleans.


Spotter activation may be requested at some point over the week.
