Overview
- Mexico’s national weather service warned Tuesday of possible tornadoes in northern Coahuila with torbellinos in Nuevo León and Tamaulipas, plus winds near 70 km/h and very heavy rain in parts of the northeast.
- An anticyclonic circulation over the Gulf keeps a national heat wave in place, with Yucatán forecasts calling for extreme highs near 40–42°C in cities such as Mérida, Izamal, Umán and Maxcanú.
- A dryline, low‑pressure troughs, an approaching front and the subtropical jet are driving the northern instability, which can trigger hail, power outages, flash flooding and tolvaneras, the dust storms common in arid zones.
- Local snapshots underline sharp contrasts, with Nogales hot and dry near 33°C, Poza Rica expecting light afternoon rain near 28°C, and Reynosa facing about 38°C with brief showers.
- Beyond Mexico, Spain’s AEMET notes a short warm‑up with interior showers in the Valencian Community, Galicia stays dry and cool, and Argentina’s SMN reports widespread cold with no active weather alerts.
