Update 23 Sept 2026, 6:14 pm UTC

Hurricane Polo has weakened from Category 5 to a strong Category 4 as it continues to threaten Mexico's southwestern coast. The storm remains extremely dangerous, with authorities maintaining alerts for hazardous surf and heavy rain.

How it started

Tropical Storm Polo first appeared in the Pacific Ocean, off the southwestern coast of Mexico, on the night of September 20. Early forecasts from meteorological agencies warned of the potential for rapid intensification, citing warm ocean waters fueled by a strong El Niño pattern.

By September 21, forecasters were already predicting that Polo could become a major hurricane within the week. The storm's early trajectory and strengthening caught the attention of both Mexican authorities and the U.S. National Hurricane Center, who began issuing advisories and warnings to residents in the region.

How it unfolded

On September 21, Polo was still a tropical storm, but models indicated it could strengthen quickly. That day, meteorological agencies noted its rapid intensification potential due to favorable ocean temperatures.

By September 22, Polo had reached Category 4 status and was continuing to strengthen. The U.S. National Hurricane Center announced that the storm could reach Category 5 strength by Tuesday or Wednesday, which it soon did.

On the morning of September 22, Polo officially became a Category 5 hurricane, with sustained winds surpassing 260 kilometers per hour. The storm was located approximately 215 miles south of Zihuatanejo, Mexico, but was not expected to make direct landfall according to forecasters at the time.

As the hurricane intensified, Mexican officials closed ports and schools in vulnerable coastal areas. Emergency authorities urged residents to stay alert for possible flooding, high surf, and landslides. Meanwhile, Southern California began making preparations for hazardous surf, rip currents, and the possibility of heavy rain, as Polo's impact could extend northward.

By September 23, Polo was being described as a "truly historic" storm and the second-strongest hurricane ever recorded in the eastern Pacific. Flash flood and mudslide warnings were issued for areas along the Mexican coast.

Where it stands

Hurricane Polo remains a powerful Category 5 storm off the Pacific coast of Mexico. While it is not expected to make direct landfall, coastal regions in Mexico continue to face threats from heavy rain, flooding, and dangerous surf conditions. Ports and schools in affected areas remain closed as a precaution.

Southern California is also on alert for hazardous weather linked to the hurricane, including strong surf and rip currents. Emergency declarations have been made and preparations are underway in anticipation of possible flooding and other storm-related impacts.

What to watch

Authorities are closely monitoring Polo's path and intensity. Any changes in the hurricane's trajectory could increase the risk to coastal communities in Mexico or Southern California. Residents in both regions should stay updated on advisories as conditions can change rapidly with storms of this strength.
