It's a fine line as the summer rainy season brings relief, and flooding, to the southwestern US

Thunderstorms are hopscotching around the Southwestern U.S., bringing much-needed moisture to a region where every drop counts. In fact, it’s the time of year when Arizona and New Mexico receive about half of their annual precipitation. Northern Mexico logs even more. From church altars and farm houses to city halls, prayers, songs and even festivals are held each year in hopes of having a bountiful monsoon from mid-June through September. The trick this season will be avoiding more devastating flooding in communities that have been ravaged by wildfires in recent years. Forecasters say this monsoon so far is packing a punch.
