Overview
- The Coordinación Nacional de Protección Civil issued a public alert on Saturday, November 7, after the Servicio Meteorológico Nacional forecast that Frente Frío 4 would bring heavy rain and colder weather to the country.
- Forecasters say the front interacting with a low‑pressure channel and the subtropical jet will likely cause torrential rains of 75–150 mm in northeast Coahuila, north Nuevo León, and northwest Tamaulipas, with very strong or strong showers in several other states.
- Authorities warn storms may produce strong winds, lightning, hail, landslides, river rises and urban flooding that could cut roads and endanger drivers and people crossing streams.
- Health and safety guidance emphasizes protecting vulnerable people from the cold, keeping heaters ventilated to avoid carbon monoxide poisoning, dressing in layers, and preparing an emergency kit with documents, light and water.
- The CNPC says it maintains constant contact with state and municipal protection units and urges the public to monitor official updates and report emergencies to 911 because conditions can change within hours.
