The worst part of the derecho that wreaked havoc on so much of Iowa its effects can be seen from space lasted about an hour and a half. Its effects will be felt for years.
August 12, 2020: MANY places with metal bins emptied before harvest look like these damaged at the Elberon elevator, with the west side punched in. That is, if the bin isn’t in a crumpled heap.
August 12, 2020: Power lines damaged just south of Newhall. The main derecho corridor was between US 20 and I-80, with the worst along US 30. KCRG reported August 16 that Blairstown may not get electricity for another week.
August 15, 2020: US 30 at V40 northeast of Belle Plaine. Eastbound signs along US 30 in Benton County look like this or have been ripped apart. More westbound signs tended to stay upright, for whatever reason. The bin seen on the IA 131 page has been destroyed. Across the road is a sunflower field that was utterly wiped out.
These pictures were taken closer to soybean fields than corn. As you drive south from Dysart to US 30, the corn goes from being at a small angle in scattered places to practically horizontal.
