Flood Watches in Phoenix & Tucson Amid Hurricane Polo Moisture
Flood watches are in effect across southern and central Arizona as moisture from Hurricane Polo combines with a Pacific storm system, increasing the risk of flash flooding. The National Weather Service has issued watches for metro Tucson from 11 a.m. Monday through 11 p.m. Tuesday, and for Phoenix-area high terrain from late Monday night through Tuesday evening. Rain chances are high, with Tucson expecting up to 80% Monday night and Tuesday, while Phoenix could see up to 60% overnight into Tuesday morning. Forecasters warn of localized heavy rain, particularly in foothills and high terrain areas, with potential for damaging winds and small hail in some storms.
