Re: Lee Rain Continues as it nears the Central Louisiana Coastline

Lee has two distinct meso vortices within its approximate mean center this morning, in addition to several other much more transient and/or ill-defined swirls that exist throughout its full expanse.

The two primary LLCs can be seen in the image below:


Despite the existence of multiple vortices within Lee, this recent scatterometer pass from 1234UTC this morning shows that, for the most part, Lee's surface circulation has become well established.


One can also see in the WindSat pass above how the entrainment of extremely dry air from Texas has manipulated the "feeder leg" into Lee (the large fetch of convection to the center's east, south and southeast), into a front-like feature.

At this point Lee has possibly become more subtropical than tropical, but this will not prevent the cyclone from dumping copious amounts of rain, particularly on its eastern half, for many days to come. As updated model runs are calling for Lee to begin pulling out of Louisiana a bit sooner and faster than earlier expected, this is a little bit better news for that state, but potentially unwelcome news for the east - possibly once again including large parts of the Mid-Atlantic and New England.
