weunice Posted May 27, 2011 Share Posted May 27, 2011 Here is a link to a video http://www.wwl.com/pages/9922474.php I got stuck in some prety stout straight line winds driving on I-12 near Lacombe and Mandeville. My car was pelted with light tree debris from the north for a few minutes. Apparently funnel clouds and a rotating wall cloud were reported in my vicinity as I was driving through. Lots of hail in the area as well but I didn't encounter that. Link to comment Share on other sites More sharing options...
weunice Posted May 27, 2011 Share Posted May 27, 2011 Can someone explain what was happening here? I left work just as I saw the couplet on radar. It appeared heavily rain wrapped by the time I saw it so any thought of positioning myself to spot it was nixed. Anyway, a cell forming to the southwest of that one produced a rotating wall cloud, multiple funnel cloud reports and some solid straight line winds. I figured driving 20 miles south of the main action was safe and there I was in the middle of it by the time I got there. All of it seemed to pop up and dissipate within an hours time (in the case of each cell). I was surprised at the intensity especially since we were not in a severe watch at the time. Was there interaction with high mid/upper level winds from the north in play here? Link to comment Share on other sites More sharing options...

Was there interaction with high mid/upper level winds from the north in play here? Mesoanalysis was showing an area of enhanced 0-1km SRH (up to 200J/kg) near that area. My guess is that some sort of boundary from Lake Pontchartrain played a role. Link to comment Share on other sites More sharing options...

weunice Posted May 29, 2011 Share Posted May 29, 2011 000 NOUS44 KLIX 272030 CCA PNSLIX PUBLIC INFORMATION STATEMENT NATIONAL WEATHER SERVICE NEW ORLEANS LA 330 PM CDT FRI MAY 27 2011 ...DAMAGE SURVEY COMPLETED FOR TORNADO IN BUSH LA... PARISH: ST TAMMANY BEGINNING POINT: 8.5 MILES W OF BUSH ENDING POINT: 3.7 MILES NW OF BUSH RATING: EF-3 MAX ESTIMATED WINDS 140 MPH PATH LENGTH: 6 MILES MAXIMUM WIDTH: 150 YARDS TOUCHDOWN OCCURRED NEAR THE INTERSECTION OF HWY 40 AND BIRTRUE RD. ONE HOME ON BIRTRUE RD SUFFERED SIGNIFICANT LOSS OF ROOF COVERING AND PARTIAL LOSS OF SECOND FLOOR STRUCTURE...SUPPORTING STRONG EF1 INTENSITY SHORTLY AFTER TOUCHDOWN. THE TORNADO MOVED ENE AND APPEARS TO HAVE BRIEFLY LIFTED BEFORE REACHING HWY 1082 AS NO DAMAGE COULD BE FOUND WHERE THE TORNADO CROSSED HWY 1082. THIS BRIEF LIFTING APPEARS TO BE NO LONGER THAN 1/4 MILE. TORNADO TOUCHED DOWN AGAIN ON THORNHILL ROAD ABOUT 1/10 MILE FROM HWY 1082 WHERE TREETOP DAMAGE WAS OBSERVED. MORE SIGNIFICANT TREE DAMAGE WAS OBSERVED FARTHER DOWN THORNHILL ROAD WITH SEVERAL TREES SNAPPED AND ONE HOME SUFFERING SIGNIFICANT LOSS...ABOUT 80 PERCENT...OF TIN ROOF COVERING. ON SHERWOOD FORREST RD...ONE TRAVEL TRAILER SUFFERED SIGNIFICANT DAMAGE...BUT WAS NOT FLIPPED AND REMAINED LARGELY IN TACT. FROM THIS AREA...THE TORNADO CONTINUED ON AN ENE TRACK AND CROSSED BOB BAXTER RD NEAR HWY 40. THE TORNADO CONTINUED TO CAUSE SIGNIFICANT DAMAGE...SNAPPING SEVERAL LARGE PINE TREES AND DOWNING POWER LINES ALONG HWY 40. ANOTHER HOME ON HWY 40 ABOUT 1/4 MILE EAST OF HWY 1083 LOST APPROXIMATELY 40 TO 50 PERCENT OF ITS ROOF COVERING. DAMAGE IN THESE AREAS SUPPORTS EF1 INTENSITY. THE WORST DAMAGE WAS OBSERVED NEAR THE INTERSECTION OF HWY 40 AND JENKINS CEMETERY ROAD WHERE ONE FRAME HOME LOST ITS ENTIRE ROOF COVERING AND ROOF FRAMING STRUCTURE. TWO EXTERIOR WALLS ON THIS HOME WERE PARTIALLY COLLAPSED INWARD AND A THIRD WALL WAS MISSING. A SECOND FRAME HOME LOST ROUGHLY 90 PERCENT OF ITS ROOF COVERING AND ROOF FRAMING STRUCTURE WITH ONE WALL PARTIALLY COLLAPSED INWARD. THE TORNADO ALSO SNAPPED 2 WOODEN POWER POLES IN THIS AREA. THIS DAMAGE WAS THE BASIS FOR THE EF3 RATING WITH ESTIMATED WINDS OF 140 MPH. FROM HERE...THE TORNADO TRAVELED ENE ALONG HWY 40 CAUSING CONTINUED SIGNIFICANT DAMAGE TO MOSTLY PINE TREES. NEARLY EVERY TREE IN THE TORNADOS PATH WAS EITHER SNAPPED OR LOST MOST OF ITS BRANCHES... SUPPORTING A MINIMAL EF2 RATING THROUGH THIS AREA. THE TORNADO CONTINUED ON AN ENE PATH TOWARD THE 5 LAKES CAMPGROUND...WHERE IT TURNED A DOUBLE WIDE TRAILER ON ITS SIDE. THE TORNADO WEAKENED A BIT MORE AS IT MOVED FURTHER INTO THE 5 LAKES CAMPGROUND...WHERE IT FLIPPED OR SIGNIFICANTLY DAMAGED ANOTHER 10 TO 15 MOBILE HOMES THAT DID NOT APPEAR TO BE TIED DOWN...SUPPORTING A STRONG EF1 RATING THROUGH MUCH OF THE CAMPGROUND. ACCORDING TO ST TAMMANY PARISH SHERIFFS OFFICE...SEVERAL RESIDENTS OF THE CAMPGROUND WERE TRAPPED AND HAD TO BE RESCUED FROM THEIR DAMAGED/DESTROYED MOBILE HOMES. ONLY 5 MINOR INJURIES WERE REPORTED...MOSTLY DUE TO FLYING GLASS AND OTHER DEBRIS. AT THE INTERSECTION OF 5 LAKES ROAD AND BERRY STREET...A FRAMED BRICK HOME LOST ABOUT 40 TO 50 PERCENT OF ITS SHINGLES WITH MOST WINDOWS ALSO BROKEN...POSSIBLY FROM FLYING DEBRIS. AN ATTACHED UTILITY ROOM WAS ALSO COLLAPSED...BUT THIS APPEARED TO BE AN ADDITION THAT MAY NOT HAVE BEEN AS STRONG AS THE HOME ITSELF. THE TORNADO DISSIPATED SHORTLY AFTER PASSING THIS HOUSE...WITH ONLY A FEW LARGE PINE BRANCHES SNAPPED ALONG BERRY STREET AND NO APPARENT DAMAGE TO THE TREE LINE BEYOND THE END OF THE ROAD. $$ DM/KEG Link to comment Share on other sites More sharing options...
gymengineer Posted June 9, 2011 Share Posted June 9, 2011 I've been looking around but can't find the data: Does anyone know how many other examples there are of EF3/F3+ tornadoes occurring in areas without any watches in place (Severe Thunderstorm or Tornado), since, say, 1990? There's another tornado warning out now in LA without a watch in place-- always kind of startling to see that. Link to comment Share on other sites More sharing options...
