in the summer in tucson, when the conditions are just right, the wind shifts to the southeast, and the extreme heat of the day sucks moisture from the baja gulf into our area. the wind picks up, throwing dust into the air, and then it pours. this is a monsoon storm. if a locality receives more than 50% 0f its yearly rainfall from such summer storms, it can claim to have a monsoon season. tucson does, phoenix doesn't. they have the occasional monsoon storm, but winter rains account for most of their yearly precipitation. in tucson, they wait to officially declare the start of the season until the humidity has risen over 40% for three consecutive days. that hasn't happened yet, but we definitely had a little monsoon storm today :)
