Storm chasers flock to the area, meaning the dangers from the storm are not your only concern.

A higher volume of traffic on the roads, persons pulled off the side of the road, and in some cases, amateurs not paying attention to the road all become a major concern.

Verno’s concerns are shared by many in the weather community. There just seem to be too many people out chasing. Here is a timelapse of chaser movement between 5 pm and 8 pm CDT on May 10 as tornadoes moved through a high risk area in eastern Oklahoma.

The yellow and red polygons are the severe thunderstorm and tornado warning polygons. The chasers are the other moving parts, congregating around the areas where the storms are expected to be. While there are dozens of chasers visible in the display, it it only shows chasers equipped with GPS devices. It does not include the armada of vehicles with the Vortex2 tornado project, which deployed near Oklahoma City. Nor does it include amateur, untrained eyes out on the roads looking for tornadoes.

I am not in any position to tell people what they should and should not do if they want to see storms. It is that part of nature’s majesty that attracted lots (if not most) of the top meteorologists into the field. But with so much traffic clogging the roadways near tornadoes, there is just no way everyone will have a clear escape route if a tornado heads toward a crowded group of amateur and professional onlookers. It’s not a question of “if” there will be storm chasers hurt, but when it will happen.
