The first dust storm of the 2014 monsoon barrelled into Phoenix, Arizona, last night, as winds of more than 80km/h tore down trees and cut power supplies to 25,200 utility customers in the city.

The storm provided fireworks of its own, toppling power lines, blanketing neighbourhoods with choking dust and unleashing downpours in certain areas.

An hours-long dust storm warning extended across the wider area, to other communities including Buckeye, New River, Wickenburg and Mesa.

Sky Harbour International Airport reported a wind gust of 90km/h at 8pm last night.

At least 24 inbound flights were diverted to other airports during the storm, while there were at least three cancellations.

Arizona Public Service reported 11,000 of its customers were without power, while Salt River Project had roughly 14,200 customers in the dark.

Workers scrambled to cover-up the fireworks in Ahwatukee.

The storm forced the cancellation of the village's ‘Red, White and Boom’ 4 July event.
