.NOW...



Through 7 PM, an arching outflow boundary is moving south to

southwest across the waters east of the Seven Mile Bridge. The

boundary extends north to near Naples and will enter the outer Gulf 

waters within the hour. Given the size, different sections are moving

at differing speeds. The stronger portion of the outflow located 

from near Marathon to Naples is moving southwest to west at 15 to 20

knots. Mariners encountering this segment can expect sudden wind

gusts of 25 to 30 knots from the northeast and east. In addition,

showers and thunderstorms have continued to develop along this line

and will bring added hazards of blinding downpours and bouts of

frequent lightning.
