...DAMAGE SURVEY NEAR NEW SALEM COMPLETE...

SEVERE THUNDERSTORMS CAUSED WIND DAMAGE EAST OF NEW SALEM AT
APPROXIMATELY 950 PM CDT ON SUNDAY JUNE 12. NATIONAL WEATHER
SERVICE METEOROLOGISTS SURVEYED THE DAMAGE THIS AFTERNOON...WHICH
OCCURRED ALONG A LINE FROM 4 MILES EAST OF NEW SALEM TO 9 MILES
EAST OF NEW SALEM.

TWO OUTBUILDINGS HAD ROOFS TORN COMPLETELY OFF AND ONE OF THE TWO
STRUCTURES HAD ALL WALLS COLLAPSED. THE LATTER BUILDING HAD DOORS
OPEN ON THE SOUTH SIDE WHEN THE STORM HIT. THIS CAN HAVE AN EFFECT
SIMILAR TO OPENING A PARACHUTE...SO THE GREATER DAMAGE DOES NOT
INDICATE GREATER WIND SPEEDS. NEW SALEM FIRE DEPARTMENT PERSONNEL
THAT WERE INTERVIEWED REPORTED SEEING ROTATION WITHIN THE
CLOUDS...BUT SAW NO ROTATING FUNNEL CLOUD OR ROTATING DEBRIS CLOUD
ON THE SURFACE.

ALL DAMAGE IS INDICATIVE OF STRAIGHT LINE WINDS...SINCE ALL DEBRIS
WAS BLOWN TO THE NORTHEAST. USING STRUCTURAL DAMAGE INDICATORS
SIMILAR TO THOSE USED TO RATE TORNADO WIND SPEEDS...
METEOROLOGISTS ESTIMATED THE WIND SPEEDS TO BE 85 MPH. VERY HEAVY
RAIN FELL WITH THE SEVERE STORMS...SO ONGOING FLOODING WAS ALSO
SURVEYED.

ADDITIONAL STORM DAMAGE SURVEYS ARE ONGOING. FURTHER RESULTS WILL
BE DISSEMINATED ONCE COMPILED.
