- Hurricane Polo has intensified into an extremely dangerous Category 5 storm in the Pacific Ocean with maximum sustained winds of 165 mph as it moves off the coast of Mexico.
- Although the storm is not expected to make landfall, heavy rainfall along the western coast of Mexico through Thursday presents a severe threat of life-threatening flooding and mudslides.
- The storm is forecast to weaken as it travels northwestward towards Baja California after encountering cooler waters and increased wind shear.
- A surge of moisture from the weakening hurricane could reach the Southwestern United States by the middle of next week, bringing downpours and localised flooding risks.
- Southern Arizona and Utah are identified as having the highest risk of receiving heavy rainfall, following recent severe weather and flash flooding in the region.
