Hoosier Posted March 5, 2012 Author Share Posted March 5, 2012 LMK has issued the survey from the first part of the track...note that it continued east of here. PUBLIC INFORMATION STATEMENT NATIONAL WEATHER SERVICE LOUISVILLE KY 300 PM EST MON MAR 05 2012 ...PRELIMINARY TORNADO DAMAGE REPORT FOR WASHINGTON COUNTY, INDIANA ON MARCH 2, 2012... DAMAGE TYPE: TORNADO DATE: MARCH 02 2012 BEGIN TIME: 250 PM EST END TIME: 308 PM EST EF SCALE: EF4 WIND SPEED: 170 MPH MAXIMUM BEGIN POINT: SOUTH SIDE OF FREDERICKSBURG END POINT: WOODED AREA ALONG S. FLATWOOD ROAD (EXTREME SOUTHEAST WASHINGTON COUNTY) PATH LENGTH: 18.5 MILES ACROSS WASHINGTON COUNTY PATH WIDTH: ONE-THIRD TO ONE-HALF MILE MAXIMUM (DIAMETER OF DAMAGE) INJURIES: UNKNOWN FATALITIES: 5 NARRATIVE: THE TORNADO FIRST TOUCHED DOWN ON THE SOUTH SIDE OF FREDERICKSBURG JUST SOUTH OF U.S. 150 WHERE SEVERAL TREES WERE SNAPPED OFF. IN THIS AREA, WINDS WERE ESTIMATED TO BE 90 MPH (EF1) WITH A DAMAGE WIDTH OF 30 YARDS ALONG THE SOUTH FORK OF THE BLUE LICK RIVER. ADDITIONAL TREE DAMAGE WAS OBSERVED AS THE TORNADO MOVED EAST- NORTHEAST ACROSS FARMLAND. NEAR THE INTERSECTION OF HORNERS CHAPEL ROAD AND FREDERICKSBURG ROAD, A HIGH TENSION METAL POWER STRUCTURE WAS TOPPLED ALONG WITH NUMEROUS TREES UPROOTED AND SNAPPED. HERE, DAMAGE WAS ESTIMATED AS EF2 WITH 130 MPH WINDS. ALONG PALMYRA ROAD NEAR STRICKLAND ROAD, SEVERAL TREES WERE SNAPPED WITH EF1 DAMAGE 50-100 YARDS WIDE AND ESTIMATED WINDS OF 100-110 MPH. HIGH TENSION WIRES WERE DOWN AND TREES SNAPPED ALONG WEST END ROAD JUST NORTH OF SHANKS HILL ROAD. THE TORNADO THEN TRAVELED OVER A RIDGE AND INTENSIFIED AS IT HIT STATE ROUTE 135 AT DUTCH CREEK ROAD. HERE, LARGE CHUNKS OF 3-INCH THICK ASPHALT FROM AN APPROXIMATELY 4-BY-4-YARD SECTION OF ROADWAY WAS BLOWN 10 TO 30 YARDS INTO THE ADJACENT GRASS NEXT TO THE ROAD. JUST EAST OF ROUTE 135, TREMENDOUS TREE DAMAGE WAS OBSERVED. AT THIS LOCATION, THE TORNADO WAS ESTIMATED TO BE OF EF3 STRENGTH WITH 150 MPH WINDS. THE WIDTH OF THE DAMAGE PATH ALSO BEGAN TO WIDEN, INCREASING TO 200 YARDS. TREE AND STRUCTURAL DAMAGE WAS WIDESPREAD NORTHEAST OF ROUTE 135 AS THE TORNADO CROSSED TRAINER LANE AND THEN STATE ROAD 335 TO ROBBS LANE. THE WIDTH OF OBSERVABLE DAMAGE INCREASED TO ONE-QUARTER TO ONE-THIRD OF A MILE. COUNTLESS TREES WERE SNAPPED AND UPROOTED. THE DEGREE OF DAMAGE SUGGESTED A MIX OF EF2 AND EF3 DAMAGE IN THIS AREA, WITH ESTIMATED WINDS OF 120-150 MPH. THE TORNADO CROSSED U.S. 60 JUST SOUTH OF NEW PEKIN. IMMEDIATELY EAST OF THE HIGHWAY, TREMENDOUS STRUCTURAL DAMAGE WAS OBSERVED. A WELL-CONSTRUCTED AND LARGE FACTORY BUILDING (AIRGO INDUSTRIES) WAS CLEARED TO ITS FOUNDATION SLAB WITH NUMEROUS ANCHORING BOLTS BENT IN THE DIRECTION OF THE STORM. DEBRIS FROM THIS BUILDING WAS OBSERVED ONE-HALF TO THREE-QUARTERS OF A MILE DOWNWIND. LARGE POWER POLES WERE SNAPPED. ANOTHER METAL OUT BUILDING ON THE RIGHT PERIPHERY OF THE DAMAGE PATH HAD SHEETING PULLED OFF THE BACK OF THE BUILDING APPARENTLY FROM THE FORCE OF THE INBOUND WINDS INTO THE TORNADO. THIS WAS THE AREA WHERE 5 PEOPLE WERE TRAGICALLY KILLED IN A MOBILE HOME. IN THIS LOCATION JUST EAST OF U.S. 60, DAMAGE SUGGESTED AN EF4 TORNADO WITH 170 MPH ESTIMATED WINDS, AND A WIDTH OF OBSERVED DAMAGE FROM 0.3-0.4 MILE. DAMAGE CONTINUED TO THE EAST ALONG AND SOUTH OF HURST ROAD IN EXTREME SOUTHEAST WASHINGTON COUNTY. THE TORNADO CROSSED INTO EXTREME NORTHWEST CLARK COUNTY ALONG AND NEAR DAISY HILL ROAD. IN THIS AREA, A WELL-CONSTRUCTED ONE-STORY BRICK HOUSE AT THE TOP OF A SMALL RIDGE WAS COMPLETELY DESTROYED WITH NO WALLS STANDING. PEOPLE ONSITE REPORTED THAT COWS WERE MISSING AND COULD NOT BE LOCATED. THEY ALSO STATED THAT THE TORNADO LOOKED LIKE A BLACK WALL AS IT APPROACHED. A HEAVY TRAILER CAB WAS BLOWN FROM THIS HOUSE TO ANOTHER DEMOLISHED BRICK HOME ABOUT ONE-QUARTER MILE AWAY. DAMAGE HERE SUGGESTED EF4 DAMAGE WITH 170 MPH WINDS. AS THE TORNADO RE-ENTERED WASHINGTON COUNTY NEAR THE INTERSECTION OF DAISY HILL ROAD AND WILLIAMS KNOB ROAD, WIDESPREAD DAMAGE OCCURRED. THIS INCLUDED A HOME WHICH WAS TOTALLY LEVELED AS WELL AS A COUPLE OF ANCHORED DOWN DOUBLE WIDE TRAILERS. A CAR WAS DESTROYED AND TOSSED ABOUT 100 YARDS IN THE DIRECTION OF STORM MOTION FROM ITS ORIGIN AT THE HOME. AT ONE OF THE DESTROYED TRAILERS, A DODGE RAM PICKUP TRUCK WAS TOSSED ONTO ITS SIDE AND DESTROYED IN THE OPPOSITE DIRECTION FROM THE CAR (I.E., ON THE LEFT SIDE OF THE TORNADO TRACK). HERE, EF3-EF4 DAMAGE WAS ESTIMATED WITH WINDS OF 150-170 MPH. THERE WERE ALSO SNAPPED TREES AND STRUCTURAL DAMAGE ALONG WHISKEY RUN ROAD. THE WIDTH OF THE OBSERVED DAMAGE STRADDLING THE WASHINGTON-CLARK COUNTY LINE WAS ESTIMATED TO BE ONE-THIRD TO ONE-HALF MILE WIDE, ALTHOUGH THE WIDTH OF THE MOST CONCENTRATED DAMAGE WAS NARROWER. THE LAST OBSERVED DAMAGE IN WASHINGTON COUNTY WAS NEAR S. FLATWOOD ROAD IN A WOODED AREA BEFORE THE TORNADO ENTERED CLARK COUNTY. ACROSS WASHINGTON COUNTY, PARTICULARLY EAST OF U.S. 135, THOUSANDS OF TREES WERE UPROOTED AND SNAPPED. DETAILED INFORMATION AS THE TORNADO CONTINUED THROUGH CLARK COUNTY AND POINTS TO THE EAST WILL BE FORTHCOMING LATER THIS AFTERNOON. Link to comment Share on other sites More sharing options...

Master of Disaster Posted March 5, 2012 Share Posted March 5, 2012 I agree, that really jumps out at you. Of course this tornado is already rated an EF4, and I don't see any really compelling evidence to make it higher than that. I do think that maximum winds were likely higher than 170 mph (which I believe is what the preliminary reports were). Check the notes I made about this from the SPC workshop this week. If there is NOT debarked shrubs, slab with remains of homes pulverized, vehicles thrown large distances or scouring of ground. The survey will not yield an EF5 rating regardless of how clean the slab is or if the DOD scale is EF5. The SPC is using Jarrell Texas as the benchmark for EF5 damage. During the presentation, they showed NUMEROUS pics of slab tornado strikes and each one was missing the 4 criteria I just mentioned so they left the rating at EF4 on all. In fact, he mentioned that some slab remaining strikes are vaulted lift events not scoured off the foundation which gives a false sense of strength.

Which is debatable considering that tornado was moving at like 5 mph, I don't doubt it was an F5, but this did help it inflict a maximum amount of damage on virtually everything it touched (Double Creek Subdivision most notably). And if tornadoes aren't rated EF5 (or any other rating for that matter) based on the DOD indicators, then I'm not exactly sure what the purpose of the DOD scale is in the first place.

And if tornadoes aren't rated EF5 (or any other rating for that matter) based on the DOD indicator, then I'm not exactly sure what the purpose of the DOD scale is in the first place. I can see the scale being perfect for EF0-EF4 events. But at EF5, there does need to be hard criteria. Its kind of like the EF6 question. Why isnt there an EF6? Well because after EF5, there is nothing else left to survey. So if the damage with EF5 is total, it needs to be total every time and not just scouring of asphalt or slab remaining. Wasn't it Americus GA were asphalt was scoured and it was an EF3? Link to comment Share on other sites More sharing options...

But the point was that just because something seems that way from an aerial survey, it doesn't mean that's the case on scene when really specific criteria have to be met.

And if tornadoes aren't rated EF5 (or any other rating for that matter) based on the DOD indicator, then I'm not exactly sure what the purpose of the DOD scale is in the first place. The problem is that of the 28 damage indicators, exactly four have expected wind speeds greater than 200 mph based off degrees of damage. And we're relatively lucky that these include mid-rise, high-rise, institutional (i.e. hospitals, universities, etc.) and large shopping malls that have rarely been hit by violent tornadoes. So when you see damage in these small towns where a one family house is swept clean, all that means is that expected winds were at least 200 mph and we need more evidence to suggest speeds were higher.

andyhb Posted March 5, 2012 Share Posted March 5, 2012 I think Joplin and Hackleburg/Phil Campbell are the two best examples of the utter destruction an EF5 can unleash in the EF scale era. Also, I think the fact that the Tri-State tornado is so widely accepted as an F5 and that it was over 40 years before the rating system for tornadoes began, is remarkable. Keep in mind that monster was moving at 60-75 mph. Link to comment Share on other sites More sharing options...

Baroclinicity Posted March 5, 2012 Share Posted March 5, 2012 PUBLIC INFORMATION STATEMENT...UPDATED NATIONAL WEATHER SERVICE WILMINGTON OH 425 PM EST MON MAR 5 2012 ...UPDATED INFORMATION ON CAMPBELL/PENDLETON COUNTY EF3 TORNADO IN KENTUCKY WHICH ALSO MOVED THROUGH CLERMONT/BROWN COUNTIES IN OHIO... LOCATION...NEAR PEACH GROVE KENTUCKY TO NEAR HAMERSVILLE OHIO DATE...MARCH 2 2012 ESTIMATED TIME...440 PM EST MAXIMUM EF-SCALE RATING...EF3 ESTIMATED MAXIMUM WIND SPEED...160 MPH MAXIMUM PATH WIDTH...1/4 MILE PATH LENGTH...23 MILES BEGINNING LAT/LON...38.84N / -84.35 W ENDING LAT/LON...38.90N / -83.98 W * FATALITIES...3 * INJURIES...UNKNOWN * THE INFORMATION IN THIS STATEMENT IS PRELIMINARY AND SUBJECT TO CHANGE PENDING FINAL REVIEW OF THE EVENT(S) AND PUBLICATION IN NWS STORM DATA. ..SUMMARY THE NATIONAL WEATHER SERVICE IN WILMINGTON OH HAS CONFIRMED AN EF3 TORNADO FROM NEAR PEACH GROVE KENTUCKY TO NEAR HAMERSVILLE OHIO ON MARCH 2 2012. ** UPDATED INFORMATION BELOW ** AN ADDITIONAL STORM SURVEY WAS CONDUCTED ON MONDAY MARCH 5TH TO DETERMINE IF THE EF3 TORNADO THAT AFFECTED CRITTENDEN/PINER/MORNING VIEW KENTUCKY WAS THE SAME TORNADO THAT AFFECTED PEACH GROVE KENTUCKY AND ACROSS THE RIVER INTO MOSCOW AND HAMERSVILLE OHIO. THE SURVEY FOUND THAT THERE IS A DEFINITE BREAK IN THE DAMAGE PATH ACROSS SOUTHWEST CAMPBELL COUNTY...WHICH IS CORROBORATED BY EYEWITNESS REPORTS SOUTH OF CLARYVILLE THAT THE FUNNEL WAS NOT IN CONTACT WITH THE GROUND AS IT CROSSED AREAS OF SOUTHWEST CAMPBELL COUNTY. THEREFORE...THE TWO EF3 TORNADOES ARE COUNTED AS SEPARATE TORNADOES...AND NOT ONE CONTINUOUS DAMAGE PATH. THE TORNADO TOUCHED DOWN INITIALLY IN SOUTHCENTRAL CAMPBELL COUNTY KENTUCKY NEAR PEACH GROVE ROAD /HIGHWAY 154/ AND CROSSED FISHER ROAD NORTHWEST OF PEACH GROVE...KENTUCKY. THE TORNADO CROSSED INTO PENDLETON COUNTY AFTER PRODUCING HIGH-END EF3 DAMAGE ON REIS RIDGE ROAD NEAR THE CAMPBELL AND PENDLETON COUNTY LINE. IN PENDLETON COUNTY...THE TORNADO MOVED ACROSS MAYS ROAD PRODUCING SIGNIFICANT AND WIDESPREAD EF2 TO LOW-END EF3 DAMAGE. THE TORNADO THEN CROSSED THE AA HIGHWAY IN PENDLETON COUNTY...AND EVENTUALLY THE OHIO RIVER AFTER CROSSING KENTUCKY HIGHWAY 8 IN PENDLETON COUNTY. THIS TORNADO HIT MOSCOW OHIO WHERE EF3 DAMAGE WAS NOTED...AND CONTINUED ON THE GROUND ACROSS CLERMONT COUNTY AND LIFTED SOUTH OF HAMERSVILLE IN WESTERN BROWN COUNTY. THIS TORNADO CAUSED EXTENSIVE DAMAGE TO STRUCTURES AND TREES ALONG ITS ENTIRE PATH ON BOTH SIDES OF THE RIVER. NUMEROUS HOMES WERE VERY HEAVILY DAMAGED OR DESTROYED...WITH MANY LOSING ROOFS...HAVING COMPLETE EXTERIOR WALL FAILURE...AND EVEN SOME MODULAR HOMES WERE COMPLETELY REMOVED FROM THEIR FOUNDATIONS...LIFTED...AND THROWN IN EXCESS OF 100 YARDS WHERE THEY WERE DESTROYED. ALSO OF NOTE ON THE SURVEY...WAS THE PRESENCE OF A LARGE AREA OF /NON-TORNADIC/ STRAIGHT-LINE WINDS ESTIMATED IN EXCESS OF 100 MPH ON THE SOUTHERN FLANK OF THE TORNADIC DAMAGE. THIS WAS PARTICULARLY NOTICEABLE IN PENDLETON COUNTY NEAR PEACH GROVE. THIS WIND DAMAGE ALSO CONSISTED OF NUMEROUS BARNS AND OUTBUILDINGS DESTROYED...AND CONSIDERABLE HOME AND TREE DAMAGE. THE DEGREE OF DAMAGE WITHIN THE TORNADIC CIRCULATION SUPPORTS WIND SPEED ESTIMATES UP TO 160 MPH...NEAR THE TOP OF THE EF3 CRITERIA. Link to comment Share on other sites More sharing options...

Well I think that means we know where the worst of the damage occurred. I mean once we heard they called in the QRT I figured we wouldn't know anything concrete until today at the earliest anyway.

But you know, you bring up a good point about forward speed as well. If Jarrell was moving at 8MPH allowing concentrated damage. Couldn't the width of the tornado at Hackleburg and Joplin be considered the same way in that the damage was so total because the winds swept the area for so long?

Hoosier Posted March 5, 2012 Author Share Posted March 5, 2012 Here is the Jefferson county part: PUBLIC INFORMATION STATEMENT NATIONAL WEATHER SERVICE LOUISVILLE KY 415 PM EST MON MAR 05 2012 ...PRELIMINARY TORNADO DAMAGE REPORT FOR JEFFERSON COUNTY, INDIANA ON MARCH 2, 2012... DAMAGE TYPE: TORNADO DATE: MARCH 02 2012 BEGIN TIME: 326 PM EST END TIME: 334 PM EST EF SCALE: EF4 WIND SPEED: 175 MPH MAXIMUM BEGIN POINT: IMMEDIATELY NORTH OF THE 3 COUNTY INTERSECTION OF CLARK, SCOTT, AND JEFFERSON COUNTIES END POINT: OHIO RIVER NEAR LEE BOTTOM PATH LENGTH: 7.3 MILES ACROSS JEFFERSON COUNTY PATH WIDTH: ONE-THIRD MILE MAXIMUM (DIAMETER OF DAMAGE) INJURIES: UNKNOWN FATALITIES: 4 NARRATIVE: THE TORNADO TRAVELED FROM CLARK COUNTY, INDIANA ACROSS EXTREME SOUTHEAST SCOTT COUNTY AND INTO FAR SOUTHERN JEFFERSON COUNTY. DAMAGE WAS OBSERVED ALONG AND JUST NORTH OF STATE HIGHWAY 362 NEAR THE 3-COUNTY LINE. THIS INCLUDED SEVERAL MOBILE HOMES TOTALLY DESTROYED, SEVERAL FRAMED HOUSES HEAVILY DAMAGED, TREMENDOUS TREE DAMAGE, AND POWER POLES SNAPPED AND SHREDDED. THE OBSERVED DAMAGE WIDTH WAS ONE-THIRD OF A MILE WITH ESTIMATED WINDS OF 170 MPH (EF4). THE TORNADO TRAVELED EAST-NORTHEAST SNAPPING TREES AND POWER POLES ON COUNTY ROAD 850, AND DID ITS MOST SIGNIFICANT DAMAGE AT THE INTERSECTION OF JACKSON ROAD, STATE HIGHWAY 62, AND SWAN ROAD ABOUT 2 MILES SOUTH OF THE TOWN OF CHELSEA. IN THIS AREA, SEVERAL WELL-BUILD BRICK HOMES WERE DESTROYED. THE HOMES HAD ANCHOR BOLTS ATTACHED TO STEEL PLATES AND A CONCRETE FOUNDATION. ONE HOUSE WAS LIFTED AND SLID 65 YARDS OFF ITS FOUNDATION WHILE MOSTLY STILL INTACT. ANOTHER HOME WAS COMPLETELY DEMOLISHED AND THROWN DOWNWIND SEVERAL HUNDRED YARDS, WITHIN WHICH THERE WERE 3 FATALITIES. THE GARAGE OF THIS HOUSE WAS DESTROYED WITH ONE VEHICLE THROWN 30 YARDS AND ANOTHER TOSSED 75 YARDS. A PIECE OF FARM EQUIPMENT WAS THROWN 200 YARDS AS WELL. A THIRD WELL-BUILT BRICK HOME HAD ITS ROOF COMPLETELY LIFTED AND THROWN OVER 300 YARDS DOWNWIND. ALSO, AN ABOVE GROUND POOL HALF FILLED WITH WATER WAS MISSING. WIND SPEEDS IN THE AREA WERE ESTIMATED AT 170-175 MPH (EF4) WITH A DAMAGE WIDTH OF ONE-QUARTER MILE. THE TORNADO TRACKED TO THE NORTH OF PAYNESVILLE AND SOUTH OF LEE BOTTOM EXTENSIVELY DAMAGING FORESTS IN SOUTHERN JEFFERSON COUNTY BEFORE CROSSING THE OHIO RIVER INTO TRIMBLE COUNTY, KENTUCKY. THE DAMAGE WIDTH NARROWED IN THIS AREA TO ONLY A COUPLE HUNDRED YARDS. Link to comment Share on other sites More sharing options...

Couldn't the width of the tornado at Hackleburg and Joplin be considered the same way in that the damage was so total because the winds swept the area for so long? Perhaps, although even with the larger size of them, I'd have to think that the areas they affected did not see the length of highest wind speeds that the Jarrell tornado inflicted (considering Joplin was moving at 30-40 mph and Hackleburg was racing at over 55 mph). Jarrell was still 1/2 to 3/4 of a mile wide, keep in mind. Link to comment Share on other sites More sharing options...

Hoosier Posted March 5, 2012 Author Share Posted March 5, 2012 I'm not sure why they would "skip" over the Clark county portion unless there was some discussion about whether it was an EF5.
