Light to gentle breezes will persist across the Florida Keys
coastal waters this afternoon into tomorrow. Breezes are expected

tend to peak in the evening where periodic cautions may be
required for portions of Keys waters. Advisories are not
anticipated at this time. Shower coverage will wax and wane
between slight and a chance, with a day or two drier stretch
arriving mid week.
