Mexico's Servicio Meteorológico Nacional forecasted extreme temperatures on Sunday, April 5, due to Frente Frío 43 and a high-altitude trough. Some states hit up to 45 degrees Celsius, while others saw lows of -10 degrees with possible frost. Rains and strong winds impacted various regions.
Mexico's Servicio Meteorológico Nacional (SMN) of the Comisión Nacional del Agua (Conagua) reported contrasting weather across Mexico on Sunday, April 5, driven by the interaction of Frente Frío 43, its polar air mass, and atmospheric instability.
States like Sinaloa, central Michoacán, and northwest Guerrero saw maximum temperatures between 40 and 45 degrees Celsius. Other areas, including Baja California Sur, Sonora, Jalisco, and Oaxaca, recorded highs of 35 to 40 degrees.
In contrast, mountainous areas of Durango faced lows of -10 to -5 degrees Celsius with frost during Monday's early hours. High zones in Baja California, Sonora, and Chihuahua saw temperatures from -5 to 0 degrees, also with frost. The SMN warned of possible snow or sleet on the summits of Popocatépetl, Iztaccíhuatl, and Pico de Orizaba.
Intense punctual rains were forecast for Nuevo León and Tamaulipas, with strong winds and possible tornado formation in Chihuahua, Coahuila, Nuevo León, and Tamaulipas. Moisture from the Pacific and Gulf of Mexico caused showers in the west, center, south, and southeast, including the Yucatán Peninsula.
In Mexico City and Estado de México, highs neared 25 degrees Celsius and lows around 12 degrees, with isolated drizzles and possible strong rains with hail in Edomex.
