Overview
- Mexico’s national weather service said Monday that Cold Front No. 43 will drive heavy rain, strong norte winds, and a drop in temperatures through Tuesday.
- The SMN projects 75–150 mm of rain in parts of southern Veracruz, Oaxaca, and Chiapas with 60–80 km/h gusts along Tamaulipas and Veracruz and across the Isthmus and Gulf of Tehuantepec.
- Marine guidance warns of seas up to 3–4 meters in the Gulf of Tehuantepec and 2–3 meters off Tamaulipas, Veracruz, and Baja California Sur, and a norte event means a strong north wind in the Gulf that can quickly raise waves and push water onshore.
- A heat wave lingers over the west and south with highs near 40–45 °C while highland zones in Chihuahua and Durango could see predawn lows down to −10 °C, and interior spots like Fresnillo, Zacatecas, start the day cold and dry with little chance of rain.
- Regional forecasts also point to a warm day in Galicia that turns stormy by night with gusts near 60–62 km/h, and to a likely cyclogenesis near La Plata that brings day‑long rain and 50–60 km/h gusts on Tuesday along with a risk of short‑burst flooding.
