A quick update – yesterday’s MODIS satellite image shows the plume of smoke from a burning marsh blowing to the south-southwest, affecting a big chunk of the city of New Orleans and parts of the Jefferson, Lafourche and Terrebonne parishes:

Thick smoke was drifting yesterday over the communities of Chalmette, Braithwaite, Marrero, Galliano, Chauvin, Dulan and Theriot, then heading out over the Gulf, making a visible plume that extended nearly 300 miles from the source of the fire – much longer than the smoke plume we observed while the Deepwater Horizon rig was burning last April.
