A large area of disturbed weather over the northwestern Caribbean Sea is associated with the remnants of Harvey. Satellite images and surface observations indicate that the system lacks a well-defined circulation and surface pressures are not falling at this time. Although this system could still become better organized while approaching the Yucatan peninsula tonight and early Tuesday, tropical cyclone formation is not expected until the disturbance moves into the Bay of Campeche on Wednesday where conditions are favorable. Regardless of development, locally heavy rainfall and gusty winds are likely to spread westward primarily across Belize and the Yucatan Peninsula during the next couple of days. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent. 2. A broad trough of low pressure located near the central Bahamas and the adjacent Atlantic continues to produce disorganized showers and thunderstorms. Only slow development of this system is anticipated during the next several days while it moves west-northwestward across the Bahamas and then turns northwestward or northward near Florida and the adjacent waters. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...medium...40 percent.
