Monsoon Weather Over Pioneer Valley
I spent twelve days in Pioneer Valley, northeast of Flagstaff, Arizona photographing the summer thunderstorms associated with the monsoon weather. I shot over 70,000 exposures to assemble a dozen time lapse movies. It was the most spectacular monsoon weather I have seen in many years. Every day brought new phenomena. Each mountain creates its own orographic clouds. Look for cumulonimbus clouds that spread out when they reach the stratosphere. Lenticular clouds hover over the mountains when the speed of the air mass increases.
I shot exposures at five second intervals to assemble time lapse movies. I produced a time lapse movie for each day of weather activity.

Whenever I see the flash of lightning outside, I grab my camera and a tripod and go out in the rain.
