Area Forecast Discussion
National Weather Service Lake Charles LA
Issued by National Weather Service Tampa Bay Ruskin FL
637 PM CDT Wed Aug 26 2020
.AVIATION...
Conditions will rapidly deteriorate as Laura moves north into the
area tonight with widespread MVFR/areas of IFR ceilings and
visibilities developing. Gusty showers and thunderstorms will
continue early this evening then rain and winds will increase
overnight reaching tropical storm to hurricane force. Winds and
rain will gradually diminish from south to north during Thursday
morning as Laura moves northward and weakens.

.PREV DISCUSSION... /issued 551 PM CDT Wed Aug 26 2020 by NWS
Brownsville TX/
DISCUSSION...
Very Dangerous Cat 4 Hurricane Laura is bearing down on the SW
coastline of Louisiana and the extreme eastern portions of TX. The
latest guidance from NHC is maintaining Laura as a Cat 4 until
landfall likely resulting in catastrophic storm surge, very
dangerous and destructive winds and flooding rains. The afternoon
forecast issuance contains only small adjustments to the short
term forecast grids through the landfall of Laura and immediately
afterwards.
The eye of Laura is about 115 NM S of LCH moving NW at around 15
mph. Current LCH radar imagery indicates that the northernmost
edge of the rain shield from Laura is starting to move into the SW
Louisiana Coastline.
Residents of SW LA and far eastern TX should finish up any storm
preparations over the next few hours as conditions should
deteriorate steadily later this evening and tonight.
