Title: YUMA DRIES OUT
 
Last September a ballyhooed hurricane named Nora formed near the Galapagos Islands and made a beeline for the mouth of the Colorado River just downstream from desert climates of Yuma, Arizona. Hi I’m Dave Thurlow for the Weather Notebook. Hurricane Nora performed a rare feat for Pacific born hurricanes, it came ashore. This has happened only a handful of times this century, but when it does more than a year’s worth of rain can fall in a few hours. So what does 3.2 inches of rain in 12 hours do to a desert that normally gets only 2.7 inches a year. Greg Gardener of Weather Notebook affiliate KAWC in Yuma reports on some of the effects of the dessert hurricane.

“Well, immediately around the city of Yuma we have a lot of agriculture land and it looks like we’ll end up with about two to three million dollars in crop damage. It only takes a little water to damage these crops and we got a lot.”

The crops that need water were destroyed, but how did the plants that don’t need water, the ones in the dessert, reacted to such a torrent.

“Out in the desert, you know, outside of town, the flowers were in bloom because of the rain. But what was kind of ironic was that with all that rain we just received, we could see sand storms from our office. Just a couple of hours after the driving rain ended, water was still running in the washes and draining basins were over flowing. But once the rain quit, the wind dried everything out and the sand started to blow.”

The desert itself has spent a long time learning how to be a dessert and when what we in moist climates see as necessary rain shows up, the dessert dramatically repels it and immediately goes back to being a desert, with sandstorms, and with a little extra flowery color.
