Overview
- Mexico’s Servicio Meteorológico Nacional has issued short‑range alerts forecasting a concentrated heat wave for northeastern Baja California in early June with daytime highs near 45 °C and gusty winds that can produce dust storms.
- The SMN’s 96‑hour outlook identifies atmospheric troughs, low‑pressure channels and moisture surges from both oceans that could generate strong to intense rains across northern, northeastern, western and central Mexico, including the Valley of Mexico.
- Local morning reports show contrasting conditions elsewhere: Galician forecasts predict mostly dry, mild weather for June 1 while San José del Rincón, Estado de México, began the day cool and drizzly and Mendoza, Argentina, started mostly cloudy with isolated night showers.
- Authorities and residents in affected Mexican zones are advised to prepare for heat‑health risks, reduced visibility from tolvaneras, strained infrastructure and potential flash flooding, and to follow updates from SMN and local civil‑protection offices.
- The forecast links the dual threats to synoptic drivers — a mid‑to‑upper‑level trough, interior low‑pressure channels and oceanic moisture inflow — which together explain why arid border areas face extreme heat as other regions face heavy rainfall.
