Overview

A line of thunderstorms tracked southeast across northeast Iowa into eastern Iowa and northwest Illinois during the afternoon and evening of Sunday, June 30, 2019, bringing widespread downed trees and power lines as 50-70 mph winds rolled through.  The strongest winds were recorded in Dubuque County, where a wind gust of 76 mph was observed at the Dubuque Regional Airport.  Several hometowns were without power after the storms passed. 

***********************************************************************************************

A storm survey team assessed damage in Dubuque county and found three swaths of 70-90 mph winds, with isolated 100 mph. Numerous farm buildings and trees were destroyed along the paths.  The approximate path areas were from Epworth to Fillmore, 3 N of Bernard to Bernard, and Asbury to Dubuque.

An anchored mobile home was destroyed 4 S of Epworth with 2 injuries.  Further southeast along the Epworth to Fillmore track, a home lost its roof.  Another injury occurred near Bernard at 14029 Ryan Rd, where a barn was partially destroyed and trees snapped off.  All injuries were not life threatening.
