Heavy rain producing thunderstorms, some severe, formed along a line in southwest Mohave County extending from Kingman to Lake Havasu City. The storms formed in the vicinity of Kingman and Golden Valley then quickly spread to the southeast dumping heavy rain across the entire area. The Mohave County Sheriff's Office reported widespread street flooding in Kingman, Golden Valley, Mohave Valley and Lake Havasu in roughly the same period of time. Local washes were flowing almost at full capacity and Interstate 40 near Topock was blocked for a short period by two feet of water and mud flowing over the road. No significant flood damage was reported.
