Hurricane Lorenzo (category 1) should make landfall in Mexico by morning. Tropical Storm Karen is weakening (wind shear), but should strengthen in a few days and possibly head for the east coast.
Update: 9-28-07: Lorenzo is now a tropical depression, and Karen has weakened further and may be fizzling out. And there's another tropical wave coming off Africa--TD#14, which is also being affected by wind shear. Btw, a weatherman said that the time for storm development from waves coming from Africa is pretty much over; now most storms will develope in the Carribean.
