STORM SURVEYS OF SEVERAL AREAS OF DOWNED TREES IN BLAIR...
BEDFORD...FULTON...SOUTHERN CENTRE AND HUNTINGDON COUNTIES HAVE
REVEALED LARGE AREAS OF BLOW-DOWN. IN THE SURVEYED AREAS...THE
COMBINATION OF WET LEAVES...WET SOILS AND STRONG WINDS CAUSED TREES
TO TOPPLE. IN MOST CASES THE TREES CAME DOWN WITH ROOT BALLS INTACT.
THE BLOW DOWN WAS MAINLY CONFINED TO EASTERN SLOPES AND VALLEY
LOCATIONS AT THE FOOT OF THESE SLOPES. 

BLUE KNOB STATE PARK EXPERIENCED LARGE AREAS OF BLOW DOWN ALONG THE
EAST FACING RIDGES. BASED ON REPORTS FROM THE PARK...MOST OF THE
TREES FELL FROM 8 PM THROUGH 9 PM FRIDAY NIGHT SEPTEMBER 17TH. SOME
EARLIER DAMAGE WAS OBSERVED AT 730 PM. INITIAL ESTIMATES SUGGEST
AROUND 800 ACRES OF FOREST EXPERIENCED BLOW DOWN. POCKETS OF
BLOW-DOWN WERE OBSERVED ON BOTH SIDES OF BLUE KNOB STATE PARK AND IN
PAVIA. EAST FACING RIDGES ALONG BLUE KNOB ROAD FROM PAVIA INTO THE
PARK EXPERIENCED EXTENSIVE BLOW-DOWN. MOST OF THE TREES FELL FROM THE
NORTHEAST.

ANOTHER LARGE AREA OF BLOW-DOWN WAS FOUND IN ROTHROCK STATE FOREST ON
THE EASTERN SLOPES AND VALLEY AT THE FOOT OF TUSSEY MOUNTAIN. ONE
AREA OF BLOW-DOWN WAS ALONG THE CENTRE HUNTINGDON COUNTY BORDER ALONG
HARRYS VALLEY ROAD. EXTENSIVE AREAS OF BLOW DOWN WERE FOUND ON THE
WEST SIDE OF DIAMOND VALLEY ROAD. A TREE DESTROYED A CAMPER AT CAMP
BLUE DIAMOND AND ANOTHER TREE DAMAGED A HUNTING COTTAGE ABOUT 3 MILES
SOUTH OF BLUE DIAMOND CAMP. SIMILAR DAMAGE WAS REPORTED FARTHER NORTH
NEAR PENN ROOSEVELT STATE PARK ALONG STONE CREEK ROAD. MOST OF THE
TREES FELL FROM THE NORTHEAST. MOST OF THE DAMAGE WAS CONFINED TO
HUNTINGDON COUNTY.

ANOTHER AREA OF SPORADIC BLOW DOWN WAS FOUND ALONG BLACK BEAR ROAD IN
FULTON COUNTY. MOST OF THE TREES FELL FROM THE NORTHEAST ON THE
EASTERN SLOPES OF SIDELING HILL.

THERE WERE POCKETS OF BLOW DOWN IN BLAIR COUNTY. THERE WERE SEVERAL
TREES UPROOTED IN ALTOONA AND NEAR THE COUNTY LINE NEAR BLUE KNOB AND
ON BRUSH MOUNTAIN.

THESE AREAS OF DAMAGE WERE DETERMINED NOT TO HAVE BEEN ASSOCIATED
WITH TORNADOES. THE DAMAGE PATTERN AND THE LACK OF ANY SOUTH TO NORTH
FALLING OF TREES SUGGESTS STRAIGHT LINE WIND DAMAGE. EYE WITNESS
ACCOUNTS OF PROLONGED PERIODS OF FALLING TREES ALSO SUGGEST SUSTAINED
PERIODS OF STRONG STRAIGHT LINE WIND DAMAGE.

...A SECOND WEAK F1 TORNADO CONFIRMED IN BEDFORD COUNTY...

A SURVEY OF THE AREA NEAR IMLERTOWN AND YOUNT ON 20 SEPTEMBER
REVEALED A TORNADO STRUCK THE REGION AROUND 840 PM ON FRIDAY 17
SEPTEMBER 2004. THE EAST FACING SLOPES OF THE RIDGE ALONG BRIAR
VALLEY ROAD WAS ALSO AFFECTED BY STRONG WINDS THAT BLEW DOWN TREES
SHORTLY AFTER MIDNIGHT. THIS AREA WAS STRUCK BY TWO DISTINCTLY
DIFFERENT EVENTS.

THE DAMAGE AND SNAPPED TREES NEAR YOUNT SUGGEST A WEAK F1 TORNADO
TOUCHED DOWN SOUTH OF YOUNT ALONG STATION ROAD. THE TORNADO MOVED
NORTHWESTWARD CAUSING SPORADIC DAMAGE ALONG YOUNTS ROAD AND NEAR 
2621 BRIAR VALLEY ROAD. THE MAIN DAMAGE WAS SNAPPED AND UPROOTED
TREES SUGGESTING WINDS OF 70-75 MPH. ON BRIARS VALLEY ROAD...THE
TORNADO LIFTED OFF A BARN ROOF. IT ALSO UPROOTED AND SNAPPED TREES AS
IT MOVED UP THE HILL FROM THE FARM.

THE TORNADO HAD ABOUT A TWO AND ONE QUARTER MILE LONG PATH THAT WAS
ABOUT 50 YARDS WIDE. THE TORNADO MOST LIKELY AFFECTED THE AREA
BETWEEN 835 PM AND 845 PM.

THERE WAS EXTENSIVE TREE DAMAGE...MAINLY UP ALONG THE EASTERN SLOPES
OF THE RIDGE ALONG BRIER VALLEY ROAD. REPORTS PUT THIS DAMAGE AT
BETWEEN 12 AND 2 AM ON THE SATURDAY MORNING. THE PATTERN OF DAMAGE
WAS SIMILAR TO THE BLOW DOWN PATTERNS AT BLUE KNOB AND ROTHROCK STATE
FOREST. THERE WAS A CONTINUOUS SWATH OF UPROOTED TREES THAT RAN FROM
NORTHEAST TO SOUTHWEST FOR ABOUT 2 MILES. ALL TREES FELL FROM THE
EAST-NORTHEAST.

THE DAMAGE NOTED HERE WAS ASSOCIATED WITH THE REMNANTS OF HURRICANE
IVAN.
