!!! The airport at Lake Charles is only 10-12 ft above sea level and is bordered on the E and W by two canals or tributaries to the main waterway. Is this where the NWS is located?

Edit -- note the 08:51Z radar image from Houston/Galveston radar shows the concentric eyewalls very well, as well as the area of intense convection that is to the NE of the inner eyewall.

Also -- there is one feeder band that has been basically sitting in the same position for a couple of hours now, going over the western shore of Lake Ponchatrain. This will be dumping rain in the lake as well as pummeling Grand Isle (southernmost tip of Jefferson County) with onshore wind and water for a very long time.
