Through 11 PM, scattered showers with a stray embedded thunderstorm
will continue to move west to northwest at 10 to 15 knots across the
waters surrounding the Florida Keys. The strongest activity will be
in the offshore waters in the eastern Straits. Within the strongest
activity, mariners may experience gusty and erratic winds of near 25
knots, heavy downpours reducing visibility, and an occasional
