Anniversary of the "Superoutbreak"

By -
Today is the anniversary of the April 3-4, 1974, Superoutbreak of tornadoes in 1974. The map below, from the late Dr. Ted Fujita, shows the geographic extent of the storms.
While the watches were good, there were lots of problems with the warnings that day as the sheer number of tornadoes overwhelmed the system and the inadequate radar was not up to the task. AccuWeather has more.

I talk more about this tornado outbreak and its historic significance in Warnings: The True Story of How Science Tamed the Weather.

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.

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
