The drought across the country is helping to cause something besides higher corn prices: dust storms.

Phoenix has been hit with some of those storms this year with another one moving through the area Saturday.

One meteorologist told the Arizona Republic that after all the dry weather from the drought, it doesn't take much to cause a dust storm.

The storms form when a thunderstorm begins to die out and rain-cooled air rushes to the ground.

That momentum kicks up sand and dust and sends it rolling. Wind speeds can soar to 80 mph or higher.

One of the reasons for the increase in these storms is the extreme heat. Phoenix had been under an excessive heat warning this past weekend, 110 degrees and above.
