11:40pm Sally Update

There is a newer forecast higher up on the blog. 

A quick update: Below is the 11:30pm satellite image with a considerable amount of lightning occurring (circled; colored dots = lightning) near the developing eye.

The cites of New Orleans (NO), Gulfport (G), Mobile (M) and
Tampa (T) are marked for reference

If you compare with the satellite images in the posting below, it is obvious the storm has become better organized and is strengthening. Those in the hurricane warning area (red in the path image in the posting below) should complete their preparations by noon Monday.

The rest of the info in the posting below is still valid.

Goodnight.
