What Not to Do in a Tornado or Derecho

By -
I was disappointed to see a member of the Iowa State Patrol violating a basic rule of weather safety during Monday's derecho: Never stop under a bridge in a tornado or high wind situation.  An underpass accelerates the wind and makes a bad situation even worse. People have been killed doing this.

Midday Monday, we told people go get off the roads ahead of the derecho. Numerous tractor-trailers were blown over the in the storm. But, if you unexpectedly find yourself in a high wind situation, pull to the side of the road away from poles, signs or other items that could be blown into your car. If possible, park your car parallel to the direction of the wind.

The above stated, take a look at the readout of his radar. It clocks a peak gust of 98 mph which seems reasonable based on the sound of the wind, the appearance of the wind-blown rain, and other wind speed reports in the area.

The brown area has a significant risk of tornadoes. Remember: if a tornado warning is issued, go to your basement and get under heavy furniture like a pool table. Of, if your basement is finished, get into the bathroom. Go ahead an put a couple of water bottles and, if appropriate, diapers in your shelter area. Wear shoes.  If you don't have a basement or safe room, go to the lowest floor and get into a bath or closet in the middle of your home. Children should be put in the bathtub.  I'll update later today.

Note: An Updated Forecast is Available HERE Freezing Rain The National Weather Service has now issued winter weather advisories, two warnings and a watch. It may be a bit too large but, when it comes to freezing rain and slick roads, caution is usually the better course of action.  Here's a color code: Deep purple is an ice storm warning; serious condition where power outages are possible. Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area. The small area of green in Illinois is for flooding and, in Nebraska, for snow.  Here is a forecast of freezing rain amounts; totals to 6am Tuesday.  Color codes: Yellow is 0.25 to 0.50 inches. Power outages may occur in this areas. Deep blue is 0.1 to .25 inc
