Tropics:
Powerful Hurricane Dean reached Category 5 status early Monday evening. It will move onshore the Yucatan Peninsula near Chetumal, then weaken as it travels west across land. It will likely strengthen some when it goes into the Gulf of Mexico, then it will make a second landfall in mainland Mexico, probably around a Cat. 2 hurricane. Texas will have no problems from the storm.
Elsewhere, a weak disturbance NNE of the Lesser Antilles (near 60 degrees west) will track west-northwest the next few days. Some slow development is possible towards the end of the week. Computer models show some type of system could move across south or central Florida and into the Gulf of Mexico over the weekend.
