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

.DAY ONE...Today and Tonight

Heat index readings of 105 to 110 degrees are expected across the
region this afternoon. A heat advisory is in effect for all of
southern Mississippi and all of southeast Louisiana excluding the
immediate coast today.

Scattered thunderstorms will be possible for areas mainly to the
east of I-55 this afternoon and early evening. Some of the storms
could turn strong and produce frequent lightning strikes, gusty
winds in excess of 30 mph, and locally heavy rainfall of 1 to 2
inches that could lead to ponding of water on low lying and poorly
drained roads.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Heat index readings may approach 110 degrees Saturday through
Monday during the afternoon hours. Heat Advisories are likely to
be issued each day through Monday due to these hot temperatures.

Scattered thunderstorms will return to the area Tuesday through
Thursday. A few of these storms could turn strong and produce
frequent lightning strikes, gusty winds in excess of 30 mph, and
locally heavy downpours that could lead to ponding of water on low
lying and poorly drained roads.
