"As strange as it sounds, they left their vehicles because the storm was overtaking them."
Stay in the car, get turned into a missile. Ever wonder what those larger pieces of "stuff" are, swirling around the funnel in tornado videos? Cars, mostly. Get out of the car and find a solid shelter. A bridge overpass, a culvert under the road, or even a low spot with something to hold onto. But get out of the car. These tornado chasers have given everybody the entirely wrong impression.
Forget the bridge overpass nonsense. And there's been a revision in thinking on what you do if you're already in a car; they're beginning to recognize you're really better off trying to avoid the tornado than stopping to get in a ditch or something.
March 1, 2000 As a new tornado season gets under way, meteorologists and emergency planners are working feverishly to buck a frightening trend: People are using highway overpasses as tornado shelters.
Meteorologist Dan Miller with the National Weather Service explains his frustration: "We routinely tell people to get down, cover up, and get as many things as possible between them and the tornado. When they get up under an overpass, theyre doing the opposite of that."
So what are your options? Dennis McCarthy, meteorologist in charge of the Norman weather office, says thats simple:
"What basically you should do is not get into that situation in the first place." He recommends being proactive by obtaining severe weather information from your nearest National Weather Service office, and then carrying out a prearranged plan to seek safety.
If you do happen to be caught in the open, here are some tips from the experts:
When the tornado is spotted and it appears possible, try to drive perpendicular to it to get out of its path. This is not openly condoned because it can backfire, says Miller. "It may be impossible to clearly see the tornado."
If theres time, abandon a car and get to a permanent building, as low and as far inside as possible.
If these fail, "you dont have any good options left," Miller says. "Theyre all bad."
Vehicles can become airborne or roll over, so they're not good shelters. Abandoning them for a ditch means youre in the open, a target for debris.
"No pun intended, but the ditch thing should be a last ditch action, your last resort," McCarthy says. He recently submitted a revised tornado safety guide to the American Meteorological Society for final approval - it's expected to be released today - in which the National Weather Service rethinks its vehicle strategy.
McCarthy: "In some instances staying in the vehicleand its not safe [to do that]might be safer than getting out of it."
Millers colleagues strongly agree that these inadequate storm-shelter substitutes are among the worst places to go when a tornado is bearing down. The rise in the embankment adjacent to the highway "elevates you in a wind tunnel with nothing to hang onto, exposing you to the tornado...."
...Evidence from May 3 refutes the tradition: Of 17 people sheltering under an I-35 overpass, all but one were blown out by the wind; one was killed. A few miles away, one person was dismembered and about a dozen others suffered serious injuries: broken backs, severed body parts, deep cuts from head to toe, recounts Harold Brooks, another research meteorologist with NSSL. Just "really ugly injuries."
