What’s Isaac up to, out there in the Caribbean?
Isaac has degraded into an impressive-looking wave. Surface-level circulation is all but gone, and convection just isn’t there. They still don’t know where it’ll steer later in the track, but it’s looking more likely to head into central America as a rain event.
Isaac is forecast to gradually weaken over the next few days
and could degenerate into a tropical wave at any time.
