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

and produce gusty winds, frequent lightning and heavy downpours that
could result in localized street flooding.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Scattered to numerous showers and thunderstorms are expected through
the period. A few of the storms each day could become strong. These
stronger thunderstorms could produce gusty winds, frequent lightning
and heavy downpours that could result in localized street flooding.

The remnants of Harvey are expected to move into the southwestern
Gulf of Mexico this week. The system currently has a high chance
of development over the next 48 hours. Continue to monitor this

This Hazardous Weather Outlook is for portions of the coastal
waters of Alabama and northwest Florida.

.DAY ONE...Today and Tonight

Winds, waves and seas locally higher in and near isolated to
scattered storms. Frequent lightning activity and visibility reducing heavy
rainfall will also be likely with the stronger storms.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Winds, waves and seas locally higher in and near storms during the
outlook. Frequent lightning activity and visibility reducing heavy
rainfall will also be likely with the stronger storms.

The remnants of Harvey are forecast to move across the Yucatan
Peninsula and emerge over the Bay of Campeche tonight where
environmental conditions are expected to become conducive for
tropical cyclone development. The National Hurricane Center
suggests a high probability of tropical cyclone development over
the southwest Gulf Wednesday or Thursday. Considering this, an
increase in long period swell is forecast to begin propagating up
across the coastal waters late Thursday or into Friday. Increased
swell may continue into the weekend, depending on eventual
strength of Gulf system.

This Hazardous Weather Outlook is for portions of south central
Alabama...southwest Alabama...northwest Florida and southeast
Mississippi.

.DAY ONE...Today and Tonight

Latest forecast heat indices look to range from 100 to 103
degrees today.

Isolated to scattered showers and storms forecast to develop near
the coast through the course of the morning are forecast to
increase along and north of Interstate 10 through the afternoon.
Some of the storms potentially strong. Main impacts from storms
will be brief strong wind gusts, frequent lightning and locally
heavy rain that may cause instances of nuisance type flooding in
some areas that experience poor drainage.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Highest forecast heat indices look to range from 101 to 106
degrees Wednesday and Thursday, mostly over the southern half of
the local area.

Moving into the weekend, there is potential for an increase in rip
current hazards as a potential tropical system, lifting up across
the western Gulf late in the week, brings long period swell into
the surf zone.

Main impacts from storms during the outlook will be brief strong
wind gusts, frequent lightning and locally heavy rain that may
cause instances of nuisance type flooding in some areas that
experience poor drainage.

.SPOTTER INFORMATION STATEMENT...

Activation of SkyWarn Severe Storm Spotter networks is not
expected through Monday.
