Crews are evaluating damage after a series of tornadoes that destroyed at least two western Kansas homes and left two people with critical injuries.
 
     National Weather Service meteorologist Andrew White says a storm dropped multiple tornadoes during a two-hour span Tuesday night in Ford and Hodgeman counties. Preliminary reports indicate that at least one of the twisters was a half-mile wide.
 
     White says crews will conduct a survey Wednesday in the counties to determine how many tornadoes touched down, their strength and how long they were on the ground. He says less damaging tornadoes were reported in two other Kansas counties.
 
     Besides damaged homes, White says U.S. 50 was temporarily closed because a tractor-trailer was toppled in the storm. He says a large propane tank also tipped over.
