Overview
- Mexico’s weather service reports the new Arctic‑air front moving in overnight into Sunday with a sharp temperature drop for the north and northeast and the potential for torbellinos in Chihuahua and Coahuila.
- Sonora’s civil protection confirms the front’s arrival Saturday night, noting mountain lows near 0°C, hot afternoons near 40°C in parts of the state, and gusty conditions that warrant caution.
- Low‑pressure channels and tropical moisture are driving showers from Veracruz and Oaxaca to Chiapas, Tabasco and the Yucatán Peninsula, while much of the rest of Mexico stays stable and dry.
- Argentina’s SMN issues yellow and orange alerts for sectors of Neuquén, La Pampa, Mendoza and Río Negro for heavy rain, hail and strong winds that may reach 90 km/h, as AMBA turns cooler under cloud cover.
- Elsewhere in Argentina conditions steady and warm through early week in Santa Fe, Córdoba and Tucumán, while AEMET‑based local forecasts show Galicia mostly dry with humid fog patches and Córdoba province in Spain shifting to higher rain chances late in the week.
