Mexico faces widespread heavy rains and extreme heat as monsoon and tropical wave 25 intensify
The Mexican monsoon, combined with tropical wave 25, is expected to bring heavy rainfall, thunderstorms, strong winds and extreme heat across much of the country from August 7‑9 2026. Forecasts from the Servicio Meteorológico Nacional (SMN) call for intense rain of 75‑150 mm in Nayarit (center and south) and Jalisco (west), with similarly strong precipitation in Puebla, Veracruz, Nayarit, Jalisco, Sonora, Chihuahua, Sinaloa, Michoacán, the State of Mexico, Morelos, Guerrero and other states. Wind gusts may reach 50‑70 km/h, and temperatures are projected to exceed 45 °C in Baja California and several northern and central regions.
Civil protection agencies have warned of flooding, landslides, hail, lightning and tree damage, urging residents to avoid low‑lying areas, stay hydrated, secure objects that could be blown by wind and follow official alerts. The SMN and local authorities continue to monitor the evolving situation and update forecasts as the systems interact.
