Franklin moves northward and away from the Caribbean region. A developing area of low pres in the NW Caribbean is expected to gradually become better organized through the weekend, as it drifts northward across the NW Caribbean, Yucatan Channel, and into the eastern Gulf of Mexico. A tropical depression is likely to form late this weekend or early next week in the eastern Gulf of Mexico.
