Wind, rain and more wind and possible tornados; Yikes!!!

From Chip Kasper, National Weather SErvice, Key West:

Hi everyone,

Expect 24 hours of rapidly changing, very windy, and occasionally stormy weather, with potential for severe thunderstorms from late tonight through Sunday morning.
*Gale Warning* has been issued for all marine zones adjoining the Florida Keys for the period 0400-1300 EST (4:00 a.m.-1:00 p.m. EST) Sunday.  Gale-force (sustained) winds begin at 34 knots, or Beaufort Force 8.  The gentle southeast breezes this evening will turn out of the south and freshen to near 20 knots by midnight.  Winds then will shift out of the southwest overnight, while increasing to a steady 30 knots over open water, with frequent gusts of 35 knots, and higher in squalls.  Meanwhile, an intensifying low-latitude, low pressure system over the western Gulf of Mexico will move rapidly eastward overnight, supported by an energetic jet stream aloft.  The ingredients will come together quickly to support a fast-moving band of strong to severe thunderstorms (wind gusts 50 knots or greater possible) which likely will sweep through the Florida Keys and adjacent coastal waters, probably between about 0500-1000 EST (5:00 a.m.-10:00 a.m. EST) Sunday.  We are launching a rare overnight weather balloon to support a severe weather threat analysis by our forecasters here in the Florida Keys, and at the Storm Prediction Center in Norman, Oklahoma.  Stay tuned for possible severe thunderstorm or tornado watches overnight or early Sunday.
Winds will shift out of due west, following the squall line Sunday morning.  Winds then will shift out of the northwest, and start diminishing to 25 knots Sunday afternoon, with cloudy and windy, but rain-free weather setting in.
