Strong thunderstorms developed during the late afternoon hours across southwest Arizona, and they generated strong gusty easterly outflow winds in excess of 40 mph. The gusty winds spread into portions of the lower Colorado River valley, including Blythe, and created dust storm conditions.

Thunderstorms across southwest Arizona generated strong gusty outflow winds in excess of 40 mph during the late afternoon hours on July 6th. The easterly outflow winds spread into eastern Riverside county during the evening hours, and picked up significant dust and sand, creating dust storm conditions. A trained spotter at the Blythe airport reported visibility to near zero miles at 1716MST, and similar conditions were expected to affect the Interstate 10 corridor from Blythe westward to Eagle Mountain. As a result a Dust Storm Warning was issued for eastern Riverside county from 1730MST through 1900MST.
