See, It Can Happen Here, Just Not Very Often.

Many people have the mistaken idea that tornadoes can’t happen in Oregon. Well if you need proof stronger than past history just look back at last Tuesday April 14. As you probably already know a small short-lived tornado touched down at about 4:10 PM on the campus of Lane Community college.

According to the LCC account: “At approximately 4:10 this afternoon witnesses reported that a funnel cloud touched down on the southwest corner of the parking lot on the main campus. The funnel cloud picked up two vehicles and moved them, flipping one of them into a center median. As soon as this was reported, an alert was issued via our campus PA system to shelter-in-place.”

As soon as I found  out about it I shared the LCC Facebook post on the EDN Facebook page and commented that it was not yet a confirmed tornado. As it turned out I discovered that the National Weather Service Forecast Office in Portland did in fact make the formal statement confirming that it was indeed a tornado. “000 NWUS56 KPQR 150057 LSRPQR PRELIMINARY LOCAL STORM REPORT NATIONAL WEATHER SERVICE PORTLAND OR 557 PM PDT TUE APR 14 2015 ..TIME… …EVENT… …CITY LOCATION… …LAT.LON… ..DATE… ….MAG…. ..COUNTY LOCATION..ST.. …SOURCE…. ..REMARKS.. 0405 PM TORNADO EUGENE 44.05N 123.11W 04/14/2015 LANE OR PUBLIC AT 405 PM A SMALL TORNADO OF UNKNOWN INTENSITY BRIEFLY TOUCHED DOWN ON THE CAMPUS OF LANE COUNTY COMMUNITY COLLEGE. A LANE COUNTY COMMUNITY COLLEGE OFFICIAL WITNESSED A RAIN AND HAIL WRAPPED TORNADO THAT DAMAGED THREE VEHICLES SIGNIFICANTLY. DELSON”

I still wasn’t ready to say it was a tornado. My reason was, with my years of experience in tornado prone areas around the country and even here in the Eugene/Springfield area, the National Weather Service is usually reluctant to call it a tornado without having one of their own personnel view the site and speak with any witnesses to the event. What I didn’t know then was that there were two particularly credible witnesses. One was a member of the LCC Security patrol and the other was a climatologist who called the weather service to report it. Both described the scene so well and added to the way the vehicles were damaged the declaration was made.

The next day the Weather Service updated their previous statement. “000 NWUS56 KPQR 151559 LSRPQR PRELIMINARY LOCAL STORM REPORT…CORRECTED NATIONAL WEATHER SERVICE PORTLAND OR 859 AM PDT WED APR 15 2015 ..TIME… …EVENT… …CITY LOCATION… …LAT.LON… ..DATE… ….MAG…. ..COUNTY LOCATION..ST.. …SOURCE…. ..REMARKS.. 0405 PM TORNADO EUGENE 44.05N 123.11W 04/14/2015 F0 LANE OR PUBLIC AT 405 PM A SHORT DURATION TORNADO TOUCHED DOWN ON THE CAMPUS OF LANE COMMUNITY COLLEGE. A LANE COMMUNITY COLLEGE OFFICIAL WITNESSED A RAIN AND HAIL WRAPPED TORNADO THAT DAMAGED THREE VEHICLES SIGNIFICANTLY. ONE VEHICLE WAS MOVED APPROXIMATELY 125 FT AND ENDED UPSIDE DOWN ON A BERM IN THE PARKING LOT. WIND SPEEDS NEEDED TO MOVE VEHICLES NEED TO BE IN THE 65 TO 85 MPH RANGE AS A CONSERVATIVE ESTIMATE…WHICH WOULD RATE THIS AS AN EF0 TORNADO. 4/15 ) A LOT OF THE WORK THIS MORNING HAS CENTERED AROUND DETERMINING THE RATING OF YESTERDAYS EUGENE TORNADO…WHICH STRUCK A PARKING LOT OF LANE COMMUNITY COLLEGE AND OVERTURNED A FEW VEHICLES. GIVEN THAT THERE WAS NO DAMAGE TO OTHER STRUCTURES…AND THE WIND SPEEDS REQUIRED TO LIFT VEHICLES ARE SOMEWHAT OF AN UNKNOWN AND EVOLVING AREA OF RESEARCH…THE STORM PREDICTION CENTER RECOMMENDED AN EF-U RATING…THE U STANDING FOR UNKNOWN. SINCE THERE IS NO EXISTING NWS DIRECTIVE AT THIS POINT WHICH SUPPORTS AN OFFICIAL EF-U RATING…THE RECOMMENDATION WAS TO RATE IT AN EF-0…AS NO DAMAGE TO OTHER STRUCTURES WAS FOUND NOR REPORTED.

In  previous article from April 4, 2014 called Dorothy Couldn’t Get To OZ With One. I explained, in very basic terms, how tornadoes form. The first description explains tornadoes in the Midwest and elsewhere, but not here in Oregon. In this state I said we average about 3 tornadoes per year over recoded history. The Midwest tornadoes form when the hot humid air rises high up into the atmosphere where the air is colder. The higher that air raises the stronger the tornado can be. This is why we have what are termed “cold core” tornadoes here. The cold air has to drop down to meet the warmer air which just doesn’t reach up far enough. That makes a weaker funnel which usually spends about 10 minutes or so on the ground and does very little damage.

You might remember back in 1996 a small tornado dropped down in the Gateway area damaging and moving a shed. The National Weather Service in Portland sent one of their meteorologists here to check it out. Our National Weather Service Office in Eugene was still in operation, but closing soon, and the last remaining meteorologist also examined the site. If I remember correctly the  Portland report was that it was not a tornado because there was no drag mark on the ground.The Eugene report said it was a tornado due to the angle of the damage and eyewitness reports. Proving what causes this kind of damage is not as simple as you might think.

The last time I checked the statistical information not one person has ever been reported to die in Oregon as a direct result of a tornado. Don’t get too cocky about that because the odds may be against having one, but if it hits you I don’t think you’ll think it’s such a rare event. If you see one or a tornado warning is issued by the authorities take shelter immediately in an interior room with no windows and a narrow roof line. A good example is a closet. Get down on the floor, cover your head and hug the wall until it is over.
