The National Weather Service Damage Assessment Toolkit (DAT) is a post-event storm survey platform that provides information from NWS damage surveys typically following tornado events. NWS Quad Cities / Davenport has completed a couple of such surveys following tornadoes during storms last week. The IEM offers a visualization of the "DAT tracks" that combines NWS Tornado Warnings along with an estimated track timing. The shown tornado tracked just southeast of Maquoketa. There are also Public Information Statements (PNS) associated with these DAT events with this PNS covering this featured tornado. The IEM also maintains a simple google email group that anybody can subscribe to receive emails when the NWS publishes such PNS damage survey results.
