Monsoons bringing rain across the Southwestern U.S. could help break droughts.

The rain comes as virtually the entire Grand Canyon state is under some level of drought, according to a map from the U.S. Drought Monitor released Thursday

The heaviest rain is concentrated in the worst drought regions in Arizona, which are along the border of New Mexico up the eastern side to the Utah border, CNN reported. Flash flood watches are currently in effect in all three states.

The National Weather service said the monsoon driven by heavy rainfall is expected through the weekend.

There is a moderate risk of excessive rainfall in parts of Arizona and New Mexico through Sunday morning. A slight risk of excessive rainfall is also in place for parts of southwest Utah, central New Mexico and southwest Colorado.

Roughly 1-4 inches of rain fell across the Tucson, Ariz. area on Friday, CNN reported.

Tucson International Airport recorded 0.48 inches of rain Saturday morning, pushing its monthly total to 3.45 inches of rain as of June 15, the National Weather Service said. More rain was expected on Saturday.
