Overview
- National agencies updated guidance on Monday, Sept. 14, with AEMET, Argentina’s SMN and Mexico’s CONAGUA giving coordinated short-term forecasts and official warnings.
- In Galicia, AEMET forecasts clear, dry conditions with daytime highs in the low–mid 30s Celsius and no precipitation expected for several days, followed by a modest cooling later in the week.
- The SMN reported a cold weekend in the Buenos Aires metro area and issued yellow alerts for extreme cold on Monday along with yellow warnings for rain and snow in southern provinces.
- CONAGUA and the Mexican SMN warned that the Mexican monsoon plus tropical wave No. 39 and low-pressure channels will bring very heavy to intense rains, with some areas forecast 75–150 mm and a heightened risk of flash flooding.
- Officials advised practical precautions: protect vulnerable people from cold exposure in Argentina, prepare for possible flooding and localized damage in affected Mexican states, and note that Galicia’s dry spell favors outdoor activity but will shift to cooler nights later in the week.
