Overview
- Mexico's Servicio Meteorológico Nacional issued alerts on July 7–8 for intense afternoon and evening rains in four southeastern states with possible accumulations of 75–150 mm and a simultaneous heat wave pushing temperatures above 45°C in the northwest.
- Spain's Agencia Estatal de Meteorología kept an orange heat warning for the entire Community of Madrid for July 8 while local forecasts in Galicia report dry, warm days with afternoon gusts of 25–40 km/h in many towns.
- Argentina's Servicio Meteorológico Nacional issued a yellow alert for extreme cold across multiple provinces and an orange alert for snow and strong winds in Neuquén and Río Negro, warning minimums near 1°C that pose special danger to children, older adults and people with chronic illness.
- Officials across the three countries warned of direct impacts including river rises, urban flooding, landslides, strong wind damage and heat‑ or cold‑related health threats and advised people to avoid flooded crossings, limit sun exposure, stay hydrated and monitor agency updates.
- Forecasters say the events have different causes—Mexico's pattern is tied to a tropical wave, upper‑level cyclonic circulations and a low‑pressure channel, Argentina's cold reflects a polar air intrusion, and Spain's heat is driven by a summer heat dome—which could prolong localized hazards and disrupt travel and services in affected areas.
