Norbert Brings Flooding and Record Rains to the Southwest
Yesterday (Monday Sept 08) brought considerable moisture to Southern Arizona and Nevada, as both the Tucson and Phoenix metropolitan areas saw considerable flooding, including record rainfall totals for both areas. This moisture was brought in by Hurricane/TS Norbert, and had been anticipated since it began curving back into the Pacific coast. There is precedent for this type of moisture, as Mike Crimmins laid out in his blog post addressing the moisture that TS/Hurricane systems bring to the Southwest, but it remains difficult to predict the exact effect of these storms. The experience in both Tucson and Phoenix show how disruptive and fast moving these storms (and their runoff) can be, as well as how quickly these waters can subside once they move through.
