National Weather Service Reports Iowa Winds Faster Than Estimated

The National Weather Service is reporting new estimates for the wind speed during last week’s destructive storms in Iowa. Meteorologists now say the straight-line winds were between 110 and 130 miles-an-hour August 10^th. A transmission tower collapsed when wind speeds north of Marion reached 130. The National Weather Service is saying that speed would be equivalent to a strong EF2 tornado. Damage assessments led to the revision of wind speed estimates.
