Monsoon Season in Tucson May Get Boost from Tropics
US · Published Sep 24, 2026
• As the 2026 monsoon season nears its end, southern Arizona could see a surge in moisture from multiple tropical systems, including Hurricane Polo.
• The storm, which has made history as one of the strongest in the Pacific Basin, is expected to remain offshore but may contribute to increased rainfall in the region.

Impact & Risks

The potential influx of tropical moisture could lead to increased rainfall in southern Arizona, particularly in areas prone to monsoonal activity. While the exact impact remains uncertain, there is a possibility of localized heavy rain and flash flooding, especially in washes, low-lying areas, and regions with recent burn scars. Residents should remain vigilant as the situation evolves, particularly in areas with a history of flooding during the monsoon season.
