This is already the deadliest year for tornadoes in a decade.
The National Weather Service says 110 people have died, and almost 1,200 twisters have been reported. That number is likely to be revised downward, but a meteorologist says 2008 is on track "to break all previous counts through the end of the year."
The record for the most tornadoes in a year is 1,817 set in 2004.
Not only are there more storms, but they're stronger. At least 22 tornadoes this year have been rated three or higher on the five-step Enhanced Fujita scale. The twister that devastated Parkersburg, Iowa, on Sunday was the first category-5 tornado in the U.S. in over a year.
Dicey conditions are expected to stick around Tornado Alley for about another week.
