...DAMAGE SURVEY FROM WATONWAN COUNTY...
TWO TORNADOES STRUCK WATONWAN COUNTY TUESDAY EVENING AUGUST 1.
THE FIRST TORNADO WAS RATED AS F3. IT TOUCHED DOWN ABOUT 715 PM...5.5 MILES SOUTHWEST OF BUTTERFIELD...JUST EAST OF THE WATONWAN/COTTONWOOD COUNTY LINE. IT MOVED NORTHEAST AND PRODUCED SOME DAMAGE AT ONE FARMSTEAD...INCLUDING SCATTERED DOWNED TREES AND THE PARTIAL REMOVAL OF ROOFS OFF TWO LARGE SHEDS.
THE TORNADO THEN MOVED ACROSS CORN AND BEAN FIELDS... BEFORE REACHING ANOTHER FARMSTEAD...AND DEVASTATING IT. THIS WAS WHERE THE F3 DAMAGE OCCURRED. A HOUSE WAS LEVELLED...BUT IT HAD BARELY BEEN ATTACHED TO THE FOUNDATION. A 60 FOOT CONCRETE BASE SILO WAS TOPPLED AND ROLLED... BUT IT HAD JUST BEEN RESTING ON THE GROUND AND WAS NOT ANCHORED. VIRTUALLY ALL BARNS...SHEDS AND OUTBUILDINGS WERE COMPLETELY DESTROYED. A PICKUP TRUCK AND TRAILER WERE ROLLED BUT NO VEHICLES WERE SENT AIRBORNE. THERE JUST WAS NOT ENOUGH TO SUGGEST THAT IT MIGHT BE MORE THAN AN F3...AND SO THIS TORNADO WILL BE GIVEN AN F3 RATING. THREE MEN AVOIDED INJURY WHEN THEY TOOK COVER UNDER A STAIRWELL IN THE BASEMENT.
SHORTLY AFTER HITTING THIS FARMSTEAD...THE TORNADO ROPED OUT AND DISSIPATED AT ABOUT 722 PM...ABOUT 5 MILES SOUTH-SOUTHWEST OF BUTTERFIELD. THE MAXIMUM WIDTH WAS 1/4 MILE...AND PATH LENGTH WAS 1.5 MILES. THE FIRST TORNADO WARNING FOR WATONWAN COUNTY WAS ISSUED AT 703 PM...VALID UNTIL 745 PM. DUE TO THE ONGOING THREAT FARTHER EAST...THIS TORNADO WARNING WAS REISSUED AT 739 PM...VALID UNTIL 830PM.
THE SECOND TORNADO IN WATONWAN COUNTY WAS RATED AN F1. IT TOUCHED DOWN ABOUT 743 PM... 4 MILES SOUTH OF ST. JAMES. WITHIN 1/4 MILE OF TOUCHDOWN... IT MOVED ACROSS A FARMSTEAD JUST NORTH OF COUNTY ROADS 10 AND 27. NEARLY EMPTY GRAIN BINS WERE DENTED... SHEDS WERE DEMOLISHED... A HOUSE LOST ITS GARAGE AND PARTIALLY LOST ITS ROOF...A 32 FOOT CAMPER WAS ROLLED... AND A LARGE VEHICLE WAS PUSHED A COUPLE HUNDRED FEET. A COUPLE AVOIDED INJURY AT THIS LOCATION BY TAKING SHELTER IN THE BASEMENT AFTER HEARING THE WARNING.
AFTER ABOUT ONE MILE...ANOTHER FARMSTEAD WAS HIT...DESTROYING MORE MACHINE SHEDS AND REMOVING THE ROOF OFF A BARN. WHEN IT WAS NOT HITTING STRUCTURES...IT WAS TEARING THROUGH CORN AND BEAN FIELDS.
PERHAPS THE MOST NOTEWORTHY ASPECT OF THIS TORNADO WAS ITS ERRATIC PATH. IT FIRST MOVED EAST FOR 1/4 MILE... THEN SOUTHEAST ABOUT 1/2 MILE... THEN NORTHEAST FOR ANOTHER 3/4 MILE... THEN EAST AGAIN FOR ANOTHER 1/4 MILE...AND FINALLY IT TOOK A SHARP TURN TOWARD THE NORTH FOR 1/4 MILE. THE TOTAL PATH LENGTH WAS TWO MILES. ITS MAXIMUM WIDTH WAS 100 YARDS. THE SECOND TORNADO WARNING FOR WATONWAN COUNTY WAS ISSUED AT (time missing from PNS due to typo)
LASTLY...THERE WAS A FUNNEL CLOUD ONE MILE NORTHWEST OF LEWISVILLE AT ABOUT 803 PM. NUMEROUS TRAINED SPOTTERS... LAW ENFORCEMENT OFFICERS...AND CHASERS WERE WATCHING THIS FUNNEL...AND NOBODY EVER SAW ANY TOUCHDOWN. NOR WAS THERE ANY DAMAGE.
ALTHOUGH THERE HAVE BEEN TIMES LISTED IN THIS STATEMENT...THESE ARE APPROXIMATIONS. SPECIFIC TIMES WILL BE DETERMINED BY COMPARING VIDEO TAPES...AMATEUR RADIO INFORMATION AND 911 LOGS. FURTHERMORE... PREVIOUS REPORTS OF A TORNADO IN WATONWAN COUNTY AT 703 PM TURN OUT TO HAVE BEEN IN COTTONWOOD COUNTY.
MANY THANKS MUST BE GIVEN TO EVERYONE INVOLVED IN THE REPORTING OF THIS EVENT. ZERO INJURIES IS AMAZING. SPOTTERS REPORTED WHAT THEY WERE SEEING. LAW ENFORCEMENT DISPATCHERS FREQUENTLY RELAYED REPORTS. AMATEUR RADIO OPERATORS ACTED AS SPOTTERS AND THEN IMMEDIATELY COMMUNICATED OR RELAYED REPORTS TO THE NATIONAL WEATHER SERVICE. RADIO AND TELEVISION STATIONS GAVE PEOPLE GREAT INFORMATION THAT PERSUADED CITIZENS TO TAKE COVER.
