Overview

• Mexico’s weather service said the new cold front entering the north and northeast will interact with the Mexican monsoon, low‑pressure channels and Tropical Wave No. 34 to produce heavy to intense rainfall across dozens of states.
• Hurricane Narda remained a Category 2 storm well offshore with 165 km/h sustained winds, contributing elevated seas and instability that support rains in western states including Jalisco, Colima, Michoacán and Guerrero.
• Forecasters warned of gusts of 50–70 km/h in Chihuahua, Coahuila, Nuevo León and Tamaulipas with possible torbellinos, plus 40–60 km/h along the Pacific coast and coastal waves of roughly 2–3 meters.
• Mountain areas were forecast to see minimum temperatures near 0–5 °C midweek in highlands such as the State of Mexico, Tlaxcala, Puebla and Baja California, alongside continued urban flooding and landslide risk in saturated zones.
• In Argentina, Mendoza was forecast to turn stormy on Friday with severe thunderstorms possible on the plains and snow in the cordillera, while rapid cyclogenesis late Friday into Saturday could bring strong storms, lightning and gusty winds to Buenos Aires and the AMBA.
