The National Weather Service says winds in overnight storms topped out at 80-miles-an-hour, demolishing trees and knocking out power to 50-thousand customers in the Des Moines metro area. MidAmerican Energy spokesman Kevin Waetke says it’s very slow-going restoring power because of downed trees.Waetke says several thousand customers in the Council Bluffs area also lost power in the overnight storms, but he says the bulk of the damage is in the Des Moines area, where traffic is clogged as many stop lights are out. Class is also cancelled for today in many Des Moines-area schools. He says residents who are trying to clean up their yards need to be very cautious around downed lines.Waetke says to stay away from downed wires, even if it means leaving a mess of tree limbs to sit. He says they never know if a line is energized or dead. Some areas of central Iowa got five inches of rain overnight and a flood watch covers parts of east central and southeast Iowa. A record nine inches of rain fell in Dubuque during a 15-hour period Wednesday and Thursday.
