Dust Storm in Imperial County West, California

Near zero visibility reported by Border Patrol in blowing dust from thunderstorm outflow near the junction of Highway 78 and Highway 86 south of Salton City. No accidents or injuries were reported.

An upper-level trough combined with strong instability (SB CAPE of 2000+ J/KG) and high moisture content (PWAT of 1.7+ inches) to result in the development of strong to severe thunderstorms across portions of Riverside and Imperial Counties during the afternoon and early evening hours. A complex of thunderstorms originating from southwest Arizona moved westward through Riverside while intensifying in the process. Another complex of storms then developed near the international border and affected Imperial County.
