- - Mexico’s forecast called for rain, lightning and hail across multiple states, along with a heat wave driving temperatures up to 45°C in parts of Michoacán, Guerrero, Oaxaca and Chiapas.
- - Local outlooks showed calmer pockets, with Buenos Aires set for a dry, partly cloudy day around 14°C to 22°C and Galician towns expecting morning clouds or light showers before daytime clearing and brisk northeasterly winds.
