TS Michael is in the Atlantic now--between Leslie and Africa. And it looks like the remnants of Isaac may return to the Gulf and form a low.
Update (8-5): TS Michael is still off to the east and is much smaller than Leslie.
A piece of the remnants of Isaac has made a loop and returned to the Gulf; it may or may not merge with the cold front, and if it developes further, it could become Nadine.
Update (8-6): Michael is a hurricane (cat 2) and is headed NE.
