The U.S. had been on track for its least deadly tornado year in the modern record through Dec. 19, 2015, according to severe weather expert, Dr. Greg Forbes.

All of that changed around the Christmas holiday, when an early winter tornado outbreak sent a reminder that strong and deadly tornadoes can strike in any season.

Here is a look at the worst tornadoes around the country in 2015.

#10: Eastland County, Texas, May 9, 2015

The third killer tornado of the year in the U.S. was reported near Cisco, Texas, when an elderly woman was killed in a mobile home, marking the fourth tornado-related fatality of 2015.

Winds from this EF3 tornado were strong enough to "toss two cars, one tractor and several farm implements over one mile," according to NOAA's storm events database.

Through the same period in 2014, weather.com senior digital meteorologist Nick Wiltgen says that eight killer tornadoes had resulted in 35 deaths.
