Quick Summary

Tropical Storm Polo is forecasted to rapidly intensify into a major hurricane in the Pacific Ocean by late Tuesday or Wednesday, potentially affecting parts of Mexico's Guerrero and Michoacán states with heavy rainfall between 10 to 20 centimeters, possibly up to 30 centimeters in isolated areas. As of Monday, Polo had maximum sustained winds of 105 kph and was located about 410 kilometers south-southeast of Manzanillo, Mexico. Meanwhile, Tropical Storm Odalys west of Mexico is expected to become a hurricane by midweek, while Tropical Storm Fay in the Atlantic Ocean is weakening near the Azores. This year's El Niño conditions are noted for delaying hurricane formation in the Atlantic, with no hurricanes having formed yet setting a record for the latest start to a hurricane season without one forming.

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.
