BASIN DURING JUNE. IN ADDITION...SUBTROPICAL STORM ANDREA DEVELOPED
IN MAY OFF THE NORTHEASTERN COAST OF FLORIDA. THE DEVELOPMENT OF
TWO NAMED STORMS PRIOR TO THE END OF JUNE IS NOT AN UNUSUAL

GRADUALLY ACQUIRED SOME TROPICAL CHARACTERISTICS OVER THE NEXT FEW
DAYS. ANDREA BECAME A SUBTROPICAL STORM WHILE CENTERED ABOUT 150
MILES EAST OF JACKSONVILLE FLORIDA AT 0600 UTC 9 MAY. NORTHERLY
WIND SHEAR AND DRY AIR CAUSED ANDREA TO WEAKEN BELOW STORM STRENGTH
BY 1200 UTC 10 MAY AND TO DEGENERATE INTO A REMNANT LOW ON 11 MAY.
THE REMNANT LOW LATER BECAME ABSORBED BY A FRONT ON 14 MAY.
TROPICAL STORM BARRY FORMED FROM A TROPICAL WAVE THAT SPAWNED A
BROAD AREA OF LOW PRESSURE NEAR THE EASTERN COAST OF THE YUCATAN
PENINSULA ON 30 MAY. THE LOW MOVED NORTH-NORTHEASTWARD ON 31 MAY
AND THUNDERSTORM ACTIVITY GRADUALLY BECAME MORE CONCENTRATED NEAR
THE CENTER EARLY ON 1 JUNE. THE ORGANIZATION CONTINUED TO IMPROVE
AND A TROPICAL DEPRESSION FORMED AT 1200 UTC 1 JUNE...JUST
NORTHWEST OF THE WESTERN TIP OF CUBA. SIX HOURS LATER THE
DEPRESSION STRENGTHENED INTO A TROPICAL STORM. BARRY REACHED A PEAK
INTENSITY OF 60 MPH AT 0000 UTC 2 JUNE WHILE CENTERED ABOUT 150
MILES WEST-SOUTHWEST OF THE DRY TORTUGAS. THEREAFTER...STRONG
UPPER-LEVEL SOUTHWESTERLY WINDS RESULTED IN WEAKENING AND BARRY
MADE LANDFALL IN THE TAMPA BAY AREA AS A TROPICAL DEPRESSION AROUND
1400 UTC 2 JUNE. BARRY QUICKLY LOST TROPICAL CHARACTERISTICS AND
BECAME AN EXTRATROPICAL LOW WHILE LOCATED OVER EASTERN GEORGIA
EARLY ON 3 JUNE. THE EXTRATROPICAL LOW INTENSIFIED AND MOVED
NORTHEASTWARD ALONG THE EAST COAST OF THE UNITED STATES. THE LOW
WAS ABSORBED BY A LARGER EXTRATROPICAL SYSTEM NEAR THE ST. LAWRENCE
RIVER ON 5 JUNE. THERE WERE NO REPORTS OF DEATHS OR SIGNIFICANT
DAMAGE ASSOCIATED WITH BARRY.
