Tropical Storm Polo intensified to a Category 1 hurricane in the Mexican Pacific, the National Meteorological Service (SMN) reported. [^2]

Polo formed Sunday night as a tropical storm during the 2026 Pacific hurricane season. [^3]

SMN forecasts warm Pacific waters will allow rapid intensification, with a probability it reaches major hurricane status in coming days as it passes near the Mexican coast. [^4]

For September 22-25, SMN forecasts rains of varying intensity across nearly all regions of Mexico due to the interaction of Hurricane Polo, a monsoon trough, the Mexican monsoon, low-pressure channels, and a cold front approaching the northern border. [^1]
