Through 500 pm, numerous showers with isolated embedded stronger
thunderstorms will move generally to the east to southeast at 10 to
15 knots throughout the Florida Keys and the adjacent nearshore and
offshore coastal waters. Mariners encountering the stronger of the
activity, mainly in the Straits of Florida south and east of the Dery
Tortugasm can expect blinding downpours, wind gusts of near 25 knots,
and occasional cloud to surface lightning strikes. Island
communities, mainly in the Lower Keys, can expect up to an additional
quarter to one half inch of rainfall.
