Quick Summary

Hurricane Polo has intensified into one of the strongest Pacific storms in recent decades, currently a Category 5 with maximum sustained winds of 165 mph, centered about 210 miles south of Zihuatanejo, Mexico. The hurricane is expected to skirt the southwestern coast without making landfall but still poses significant risks including heavy rain, flash flooding, and mudslides. Authorities in several Mexican states have temporarily suspended classes, closed ports, and warned civilians and fishermen to take precautions as waves and high winds threaten coastal areas.

Story summary

Hurricane Polo, rapidly intensifying to a Category 5 storm with maximum sustained winds of 165 mph (265 km/h), became one of the most powerful Pacific cyclones in decades. Centered approximately 346 kilometers south of Zihuatanejo, Mexico, it was expected to skirt the southwestern coast without making landfall but could cause significant flooding and mudslides inland due to heavy rainfall forecasts. The National Hurricane Center warned that coastal states like Guerrero and Michoacán might receive up to 12 inches (30 cm) of rain by Thursday, raising flood risks. Researchers linked Polo's unusual strength to the strong El Niño weather pattern, which has fueled extreme conditions globally this year.
