The rainfall from Hurricane Polo's moisture could provide relief to drought-stricken areas in the Southwest, but it also poses risks of flash flooding. Burn scar regions are particularly vulnerable, as they are prone to rapid runoff during heavy rain events. Communities in Arizona, Texas, and Colorado should remain alert to localized flooding risks, especially in low-lying areas and near streams. Emergency services may need to respond to sudden flooding incidents, and travel disruptions are possible in affected regions.
