Hurricane Polo raises travel disruption risk along Mexico’s Pacific coast

Hurricane Polo has rapidly intensified into a Category 5 storm off Mexico’s Pacific coast, bringing the threat of flooding, mudslides, and travel disruption to parts of the country’s southwest despite forecasts indicating it will remain offshore.

Polo was producing sustained winds of around 165mph (266km/h) on Tuesday as its centre moved around 215 miles (346km) south of Zihuatanejo in Guerrero state. Less than 24 hours earlier, the system had been classified as a tropical storm with winds below 74mph.

Mexico is currently expected to avoid a direct hit. However, the US National Hurricane Center (NHC) warned of the potential for life-threatening flooding and mudslides inland, as well as dangerous surf and rip currents along the coast.

For travellers, those secondary effects could prove more significant than the hurricane's projected track. Flooding and landslides can affect road access and ground transport, while dangerous coastal conditions can disrupt excursions and other tourism activities, potentially leading to itinerary changes and accommodation disruption.

The situation also highlights the speed with which destination risk can change for travel insurers and assistance providers. Polo strengthened from a tropical storm into a Category 5 hurricane in less than a day, potentially leaving travellers already in destination with little time to respond to deteriorating conditions.

Travellers heading to affected areas may need to monitor local authority, airline, tour operator, and accommodation advice, while insurance coverage for weather-related disruption will depend on individual policy terms and when cover was purchased relative to the storm becoming a known event.

Polo’s rapid intensification comes during an unusually strong El Niño, which is contributing to heightened tropical cyclone activity in the Pacific. The hurricane is the 18th named storm and the seventh hurricane of the 2026 Pacific season.

By contrast, the Atlantic hurricane season has so far produced six named tropical storms and no hurricanes – the first time in 112 years that an Atlantic hurricane had not formed by 21 September.

Also this week, hundreds of flights were cancelled and rail services suspended in Japan as Typhoon Dujuan brought heavy rain and strong winds to Tokyo and surrounding regions.
