.NOW...
Through 500 pm, scattered showers and isolated thunderstorms will
persist across the Florida Keys and the adjacent nearshore and
offshore marine zones. This activity will generally propagate to the
north to northwest at 5 to 10 knots. The strongest activity
southeast of Alligator Reef Light in the eastern Straits of Florida
out to 60 nm will produce blinding downpours, wind gusts to near 25
knots, and a few lightning strikes. Select island communities along
the Florida Keys, particularly near Key Largo, may receive one
quarter to one half inch of rainfall accumulation.
