Sunday Rain and Flooding Outlook

Halloween Outlook

Flood Watch is in effect for portions of Pima county, Pinal county, Graham county, and Greenlee county from 11 PM Saturday through 5 AM Monday.

A Pacific system will bring scattered showers and thunderstorms to southeastern Arizona today. Any thunderstorm will have the potential to bring heavy rain, damaging wind gusts, and hail.

A potent weather system will move through Sunday through Sunday night resulting in widespread rain and embedded thunderstorms. This will result in the potential for flash flooding. Most likely rainfall amounts will range from about 0.5" to 1.5" for much of the region with a few spots over 2 inches.

Halloween will feature a relative lull between the weather systems Friday and Sunday, however there will be a 10 percent chance of showers during the day, increasing to up to 40 percent in the evening.
