..MAY 2009 A SLOW MONTH FOR TORNADOES IN OKLAHOMA


PRELIMINARY NUMBERS FOR MAY 2009 SHOW ONLY FOUR TORNADOES WERE
REPORTED IN OKLAHOMA DURING THE MONTH. ALL FOUR TORNADOES OCCURRED
ON MAY 13TH.

MAY TYPICALLY MARKS THE PEAK OF TORNADO SEASON IN OKLAHOMA...WITH AN
AVERAGE OF 20 TORNADOES...OR ABOUT 38 PERCENT OF THE ANNUAL TOTAL.

HOWEVER, 2009 WASN'T THE SLOWEST MAY FOR TORNADOES. IN MAY 2005, NO
TORNADOES WERE REPORTED IN OKLAHOMA...AND MAY 1988 ONLY HAD TWO
TORNADOES.

OTHER YEARS WITH LOW TORNADO TOTALS INCLUDE 1958 AND 1967, WHEN ONLY
FOUR TORNADOES OCCURRED.

IT IS INTERESTING TO NOTE THAT THE MONTH OF FEBRUARY...USUALLY ONE
OF THE QUIETEST TORNADO MONTHS...WAS MORE ACTIVE THAN MAY...WITH A
TOTAL OF SIX TORNADOES...INCLUDING THE EF4 LONE GROVE TORNADO.

THESE NUMBERS ARE STILL PRELIMINARY AND SUBJECT TO CHANGE.
