Overview
- AEMET has issued a special heat‑wave notice for much of Spain and says the episode is likely to continue at least until Tuesday, with modelled easing after that still uncertain.
- Measured extremes have already been recorded in Galicia, where Vigo reached 39.1°C and Salceda 40.2°C and forecasts call for widespread highs near 38–40°C in inland valleys.
- AEMET warns of elevated nighttime minima, with 'tropical' nights above 20–25°C that raise the risk of heat‑related illness and reduce overnight cooling for homes and workers.
- Mexico's SMN and Conagua forecast that tropical waves 14 and 15 plus low‑pressure channels will produce very heavy rains, thunderstorms and possible hail in western, central and southern states while the northwest endures extreme heat of 40–45°C.
- Local authorities have issued maritime warnings in Nayarit for mar de fondo with 1–2 meter waves and wind alerts in Nuevo León for strong surada gusts, and residents and outdoor workers report heat stress, added cooling demand and altered activity patterns.
