- Separate SMN bulletins keep wide multi‑hazard warnings in force across Patagonia and Andean provinces, including heavy rain, snow, Zonda winds and red‑level cold alerts for parts of Chubut and Santa Cruz.
- Mexico's SMN forecasts widespread rain from July 30 to August 1 with very strong to locally intense totals of 75–150 mm in parts of Oaxaca and Chiapas while northern states face heat waves above 45°C driven by the Mexican monsoon and tropical wave activity.
- Local forecasts from Spain's AEMET for towns in Galicia show largely dry, warm conditions today, underscoring how the same period brings very different risks across short distances.
