...TROPICAL SYSTEMS AND THEIR EFFECTS ON ARKANSAS...

RECORDS FOR TROPICAL CYCLONES IN THE NORTH ATLANTIC BASIN BEGAN IN
1851. NO CYCLONE APPARENTLY AFFECTED ARKANSAS FROM 1851-1859.
HOWEVER...BASED ON 15 FULL DECADES OF DATA FROM 1860-2009...ANALYSIS
SHOWS THAT ARKANSAS IS AFFECTED BY A LANDFALLING NORTH ATLANTIC
TROPICAL CYCLONE AN AVERAGE OF FOUR TO FIVE TIMES IN A GIVEN DECADE.
THE FREQUENCY OF THE EXACT CENTER OF THE STORMS TO MOVE THROUGH THE
STATE IS SLIGHTLY LESS...WITH AN AVERAGE OF THREE TIMES IN A GIVEN
DECADE.

BY THE TIME THE STORMS REACH ARKANSAS OR BEGIN TO HAVE AN EFFECT ON
WEATHER WITHIN THE STATE...THEY ARE USUALLY IN THE DECAYING
STAGES...OR HAVE ALREADY BECOME A REMNANT LOW PRESSURE SYSTEM. ON A
FEW OCCASIONS...THE STORMS HAVE MAINTAINED AT LEAST TROPICAL STORM
STRENGTH WHILE MOVING THROUGH THE STATE /FOR EXAMPLE...BETSY IN 1965
AND IKE IN 2008/.

DECAYING TROPICAL SYSTEMS HAVE A HISTORY OF PRODUCING A NUMBER OF
HAZARDS IN ARKANSAS...INCLUDING TORNADOES...WIND DAMAGE...HEAVY
RAINS AND ASSOCIATED FLASH FLOODING...AS WELL AS DEVASTATING RIVER
FLOODING.

PEAK TIME FOR THESE SYSTEMS TO AFFECT ARKANSAS IS USUALLY DURING THE
MONTH OF SEPTEMBER...THOUGH STORMS HAVE AFFECTED THE STATE AS EARLY
AS JUNE 5TH /TROPICAL STORM 1 IN 1871/ AND AS LATE AS OCTOBER 30TH
/HURRICANE JUAN IN 1985/.

TROPICAL CYCLONES THAT HAVE AFFECTED ARKANSAS HAVE MADE LANDFALL
ANYWHERE FROM THE NORTHERN COAST OF MEXICO TO THE ATLANTIC COAST OF
GEORGIA. HOWEVER IT APPEARS THE MOST FAVORED AREA FOR A LANDFALLING
TROPICAL SYSTEM TO AFFECT ARKANSAS IS GENERALLY FROM ALONG THE UPPER
TEXAS COAST THROUGH THE LOUISIANA GULF COAST.

SOME OF THE MOST SIGNIFICANT TROPICAL SYSTEMS TO AFFECT ARKANSAS
WERE...

THE GALVESTON HURRICANE OF 1915...ON AUGUST 15TH THROUGH
17TH...REMNANTS OF THE STORM DUMPED EIGHT TO 14 INCHES OF RAIN ON
NORTHERN ARKANSAS AND CAUSED RECORD HIGH RIVER STAGES ON THE
BUFFALO...WHITE AND BLACK RIVERS. THE BUFFALO RIVER AT GILBERT
REACHED A STAGE OF 54 FEET. ALL CROPS ALONG THE WHITE RIVER AT OR
ABOVE DEVALLS BLUFF WERE DESTROYED.

HURRICANE BETSY...ON SEPTEMBER 11TH AND 12TH 1965...THE REMNANTS OF
HURRICANE BETSY MOVED ACROSS THE STATE WITH 50 TO 70 MPH WINDS...
AND UP TO SIX INCHES OF RAIN IN THE NORTHEAST.

HURRICANE ELENA...ON SEPTEMBER 3RD AND 4TH 1985...THE REMNANTS OF
HURRICANE ELENA MOVED THROUGH THE STATE...WITH TWO TO FOUR INCHES OF
RAIN COMMON IN CENTRAL AND NORTHEAST ARKANSAS. THE STORM PRODUCED
FLASH FLOODING IN PORTIONS OF BAXTER...VAN BUREN...CLEBURNE...AND
GARLAND COUNTIES. TWO FEET OF WATER FLOODED DOWNTOWN HOT SPRINGS. AT
MOUNTAIN HOME 8.95 INCHES OF RAIN FELL.

HURRICANE RITA...ON SEPTEMBER 24TH 2005...THE STORM MADE LANDFALL ALONG
THE TEXAS/LOUISIANA BORDER...AND MOVED ACROSS THE SOUTH AND
EAST...WITH THREE TO FIVE INCHES OF RAIN...35 TO 40 MPH WIND
GUSTS...AND TORNADOES.

HURRICANE GUSTAV...ON SEPTEMBER 2ND THROUGH 5TH 2008...THE REMNANTS OF
HURRICANE GUSTAV SLOWLY MOVED THROUGH WESTERN ARKANSAS...PRODUCING A
GENERAL FOUR TO EIGHT INCH RAIN OVER THE STATE...ALONG WITH FLASH
FLOODING AND RIVER FLOODING. THE SYSTEM SPAWNED TWO TORNADOES
ACROSS THE STATE. AT BISMARCK...11.50 INCHES OF RAIN FELL IN FOUR
DAYS.

HURRICANE IKE...LESS THAN TWO WEEKS LATER...IKE ENTERED ARKANSAS AS
A HIGH-END TROPICAL STORM ON THE 13TH...AND EXITED THE STATE ON THE
MORNING OF THE 14TH. THE STORM PRODUCED WIDESPREAD WIND DAMAGE...AS
WELL AS NINE TORNADOES...AND SOME FLASH FLOODING ACROSS THE WEST.
