(Associated Press) With only about two-dozen twisters recorded so far this year during a period when 100 or more are typical, the U.S. appears to be in a tornado drought as cool, stable air prevents the ingredients of the violent storms from coming together, meteorologists said Friday.
No tornadoes have been reported so far in March, when tornado season often begins ramping up for parts of the country. The last time the U.S. had no twisters in March was nearly 50 years ago, according to figures from the National Oceanic and Atmospheric Administration's Storm Prediction Center in Norman.
Forecasters at the prediction center reported earlier this week that since the beginning of the year, it has issued only four tornado watches and no severe thunderstorm watches — less than 10 percent of the average 52 tornado watches issued by mid-March. The center hasn't issued a watch in March, something that's never happened in its record of watches dating to 1970, said Greg Carbin, warning coordination meteorologist for NOAA's Storm Prediction Center.
