A well-developed, southeasterly monsoonal circulation had ushered in ample amounts of moisture to south central Arizona and combined with an unstable air mass, this allowed for isolated to scattered thunderstorms to form over portions of the south central deserts on June 29th. Some of the late afternoon and evening storms brought strong, gusty and damaging winds to northern Pinal County, and these winds affected communities such as Magma. Wind gusts, measured in excess of 70 mph, blew down trees as well as power poles. Injuries were not reported as a result of the strong winds.
