First let me state that I’m a trained severe weather spotter from the St. Louis County, MO, SKYWARN program and spent a decade as one of the SKYWARN lead operators of the ham radio network of spotters that feed real time spotter reports to the National Weather Service office in St. Louis during severe weather. (Note: I am a trained SPOTTER; not, repeat NOT a storm chaser!)
In answer to the question about whether the safest place is in a car, the answer is NO NO NO NO NO.
Tornados pick up and toss cars and even fully loaded semis through the air, tumbling and tumbling and often end up with the car totally crushed or wrapped around some tree or pole or building that somehow survived the winds. All the debris field in those winds will break out windows and the winds of the tornado will suck people out of the car even if they are securely belted in with seat belts. The debris in the winds is lethal if you are hit by it. Debris is moving at 100 to 200 mph or more in a tornado. That will come right through windshields and a human body. Depending on the strength of the tornado there is no safe place in a vehicle hit by a tornado.
That said, people sometimes survive unhurt having their car hit by a tornado. My dad did so when caught in his car in a twister near Pryor OK the same day that President Roosevelt died in 1945. He was damned lucky.
I’ve seen quite a lot of film footage of tornados and their aftermath and you can hardly recognize some remaining debris as having been a car or truck.
Especially in an EF5 or even a slighltly lesser EF4 tornado the only safe place is underground. An EF5 in Texas a few years ago literally scoured the slab foundations, driveways and even streets from the earth.
I grew up in Tulsa OK without a basement and we had a few close calls with tornados. I’ve even been driving a car on the turnpike within a few hundred yards of a twister when it destroyed the truck stop at the Big Cabin exit in 1979. It was a rain wrapped tornado so we couldn’t see it. But even being not directly in its path, the heavy 1965 Olds I was driving was lifted slightly and dropped one lane over. Do not care to repeat the experience! After that is when I later got involved in SKYWARN just so I would know enough to better avoid being caught up in another one unaware.
Everyone should own a NOAA weather alert radio. Even if you do not live in tornado country the weather alert radios warn of floods, blizzards, wildfires, hurricanes and other natural disasters. They save lives, especially if dangerous conditions happen at night.
OK4450, glad your family was unharmed in this recent batch of terrible tornados through Moore, El Reno, etc.
