What happened
The episode as NWS VEF wrote it up.
Severe thunderstorms unleashed damaging winds and torrential rain from Mohave Valley to near Oatman along Route 66. Flood waters blocked Route 66 around 3:15 p.m. MST, but the height of the storm struck around 3:45 p.m. producing winds which damaged 45 residential properties and tore the roof completely off a duplex. Several carports and numerous trees and power lines were blown down. The roofless duplex was quickly drenched by the heavy downpour and was condemned by authorities. Streets were filled with water and many were impassable until around 6:00 p.m. MST.
