Strong gradient winds, ahead of a deep surface low tracking along the U.S./Canadian border, produced wind gusts up to 45 mph (39 knots) across southeast portions of South Central Wisconsin and most of Southeast Wisconsin. Numerous reports of tree branches being blown down as well as power lines downed by the strong winds were received from across the region. The downed power lines created scattered power outages across the area, with WE Energies reporting 7,000 customers without power, with 2,800 of those customers on the north side of the City of Milwaukee. The U.S. Coast Guard in Milwaukee rescued 6 kayakers within the Milwaukee Harbor breakwater after their kayaks capsized in the choppy waters produced by the gusty winds.
