...DAMAGE SURVEY RESULTS OF THE MAY 6TH STORMS FROM IROQUOIS
COUNTY...

THE NATIONAL WEATHER SERVICE CONDUCTED A SURVEY OF DAMAGE ACROSS
IROQUOIS COUNTY IN EAST CENTRAL ILLINOIS THAT WAS EXPERIENCED
DURING THE STORMS ON SUNDAY AFTERNOON. ONE TORNADO WAS DISCOVERED
AMONGST WIND DAMAGE THROUGHOUT THE GENERAL WATSEKA AREA. THE
FOLLOWING ARE THE DETAILED RESULTS.

-----------------------------------------------------------------

...EF-1 TORNADO SOUTHEAST OF WATSEKA...

EVENT...EF1 TORNADO.

MAXIMUM WINDS...85 TO 95 MPH.

PATH LENGTH...1.5 MILES.

LOCATION...2.5 MILES EAST SOUTHEAST OF WATSEKA TO 4 MILES EAST
SOUTHEAST OF WATSEKA.

MAXIMUM WIDTH...ESTIMATED TO BE APPROXIMATELY 100 TO 200 YARDS.

TIME...ESTIMATED BETWEEN 4:48 PM AND 4:54 PM PER ACCOUNTS AND
RADAR IMAGERY.

DAMAGE...TWO FARMSTEADS EXPERIENCED ALMOST ALL OF THE DAMAGE WITH
THIS TORNADO...WITH THREE OTHERS HAVING SOME TREE DAMAGE. A SMALL
BARN WAS DESTROYED WITH ITS CINDER BLOCK WALLS TOPPLED AND ROOF
THROWN ONE HALF MILE. MULTIPLE OUTBUILDINGS HAD MAINLY MINOR
DAMAGE. ONE UTILITY POLE WAS DOWNED.

REMARKS...AT ONE OF THE FARMSTEADS THERE WERE SEVERAL IMPALED
OBJECTS...INCLUDING PIECES OF WOOD INTO A CAMPER AND THE
GROUND...AS WELL AS A STOP SIGN INTO THE SOIL OF AN UPROOTED TREE
BASE.

COMPLEXITIES...THIS SURVEY WAS COMPLEX WITH THE TORNADO WITHIN A
GENERAL AREA OF WIDESPREAD STRONG...AND AT TIMES SEVERE...STRAIGHT-
LINE WINDS. MANY OF THE ACCOUNTS FROM CITIZENS NEAR THE DAMAGE
AREA MENTIONED SEEING ROTATION WITHIN THE CLOUDS AT SOME
POINT...ALTHOUGH THERE WERE AREA REPORTS OF WIDESPREAD DUST AND
APPARENT WEAK GUSTNADOES IN IN ADVANCE OF STRONG WINDS AND ZERO
VISIBILITY WITHIN HEAVY RAIN SOON AFTER THAT. THERE APPEARED TO BE
STORM INTERACTION BASED ON RADAR IN THIS AREA THAT HELPED TO
DEVELOP A TORNADO NEAR THE FRONT EDGE OF THE STRONG WINDS.

HISTORY...THIS WAS THE FIRST TORNADO IN IROQUOIS COUNTY SINCE AN
EF0 OCCURRED NEAR CISSNA PARK ON JUNE 21ST 2010.

-----------------------------------------------------------------

...STRAIGHT-LINE WINDS ALONG U.S. HIGHWAY 24...

EVENT...STRAIGHT-LINE WINDS.

MAXIMUM WINDS...APPROXIMATELY 100 MPH.

AREA...A 3 MILE NARROW SWATH.

LOCATION...IMMEDIATELY ALONG U.S. HIGHWAY 24 FROM 2.5 MILES EAST
OF CRESCENT CITY TO 1 MILE WEST OF WATSEKA.

TIME...ESTIMATED AT APPROXIMATELY 4:35-4:40 PM PER ACCOUNTS AND
RADAR IMAGERY.

DAMAGE...APPROXIMATELY FIFTY 70-FOOT HIGH UTILITY POLES WERE
BLOWN OVER TO THE EAST SOUTHEAST ACROSS A RAILROAD LINE
IMMEDIATELY TO THE NORTH OF U.S. HIGHWAY 24. SEVERAL WERE SNAPPED.
A FEW LARGE TREES ALSO NEAR THE RAILROAD WERE DOWNED.

------------------------------------------------------------------

...THROUGHOUT WATSEKA...

ACROSS THE TOWN OF WATSEKA THERE WAS FOUND TO BE SCATTERED SEVERE
WIND DAMAGE. WIND SPEEDS LIKELY APPROACHED 80 MPH AT TIMES BASED
ON THE SIZE OF SOME OF THE LARGE TREES DOWNED AND A FEW UTILITY
POLES DOWNED. THERE WAS ALSO SOME MINOR ROOF DAMAGE TO A FEW
BUILDINGS.

-------------------------------------------------------------------

...NEAR ASHKUM...DANFORTH...AND GILMAN...AND NORTH OF WATSEKA...

THE NWS STORM SURVEY TEAM FOUND NO SIGNS OF DAMAGE IN THESE AREAS
DESPITE LOW-LEVEL ROTATION ON RADAR AND REPORTS OF ROTATION AND
FUNNEL CLOUDS.

------------------------------------------------------------------

THE NATIONAL WEATHER SERVICE WOULD LIKE TO THANK IROQUOIS COUNTY
EMERGENCY MANAGEMENT FOR THEIR ASSISTANCE WITH THE SURVEY...ALONG
WITH MULTIPLE CITIZENS FOR SHARING THEIR ACCOUNTS OF THE EVENT.
