May 20 -- Anniversary of Major Tornadoes

By -
Today, we commemorate many notable tornadoes. The Moore Tornado in Oklahoma was the last EF-5 intensity in the United States. Eleven years is, by far, the longest interval in history as earth's warmer temperatures have made [E]F-5's have become increasingly rare. Above is a photo of meteorologists at the National Weather Service's Norman office. Their warnings saved dozens of lives.

In 1957, the Ruskin Heights F-5 tornado was on the ground for 88 miles, including south Kansas City. The photo from the Ottawa Herald was taken near where it first touched down. 
The next morning, my mother drove us through the devastated neighborhood south of our home (we were close enough we had debris on the front lawn). We went right down the highlighted street and I saw the literally miles of rubble and shocked, shattered people. The photos are from Life magazine. I tell the entire story, here. 
Even though I was just 5 years-old, I knew I wanted to be a meteorologist after seeing all of this. 

But, on this May 20, I want to talk about perhaps the most unusual tornado occurrence of all time: the three May 20 Codell Tornadoes of 1916, 1917, and 1918. A small town in north central Kansas was struck three times in consecutive years. I wrote an article for Weatherwise magazine about those storms that was published in 1977. You'll find the PDF pages of Codell Revisited below.

The forecast path of the center of Hilary has shifted a bit to the west. This increases the threat to the Southland, especially in terms of flooding.  Rainfall Note the heavy rains are forecast for Los Angeles County. Serious flash flooding may result. Because the forecast path has shifted to the west, that increases the threat of serious flooding in Los Angeles County north into Yosemite and the southern Sierra. It lessens the threat in Utah and western Arizona. While the threat of widespread flooding in Utah and Arizona lessens, note that some thunderstorms with localized heavy rain show up on the map.  In Nevada, the more western path increases the risk of serious flooding around Mt Charleston and into the central part of the state.  Here is the updated  (9am PDT) flash flood risk map. Wind There are already about 40,000 people without power in California, mostly in the center of the state.  The maps above are the peak gusts forecasted with the storm. The highest winds, in general,

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.
