On March 8, 2025, Mexico is preparing for the arrival of Cold Front 33, which is expected to bring significant weather changes across multiple states. The Servicio Meteorológico Nacional (SMN) has issued warnings about this meteorological phenomenon, which is interacting with polar troughs and various jet streams, resulting in severe winds, possible snowfall, and fluctuated temperatures.
The forecast warns of extremely windy conditions, particularly across Chihuahua, Durango, and Coahuila, where gusts could reach between 70 to 90 kilometers per hour (km/h). According to Conagua, similar high winds are also anticipated for Zacatecas, Aguascalientes, San Luis Potosí, and Nuevo León, which may experience gusts from 50 to 70 km/h. The SMN highlighted the potential for dust storms and low visibility on roads due to these conditions.
Isolated rain showers, along with the possibility of sleet or snow, are predicted for Baja California, Sonora, and Chihuahua during the morning. These precipitation events could adversely affect local infrastructure, posing challenges for transit across affected areas. On the night of the same day, citizens of Tamaulipas should brace for another surge of wind as the Norte event is expected to begin, continuing through the early hours of March 9, 2025.
Through the eastern and southeastern areas of Mexico, Conagua expects rainfall and sporadic showers as well, particularly affecting Veracruz, Oaxaca, and Chiapas. Conversely, for much of the country, atmospheric conditions are anticipated to remain stable, resulting primarily from the presence of high-pressure systems maintaining hot temperatures. Many regions are forecasted to experience daytime temperatures exceeding 35 degrees Celsius (°C), with extreme highs of 40 to 45 °C expected to be felt across Tamaulipas, San Luis Potosí, Guerrero, and Oaxaca.
For places like Saltillo, the UV index is likely to peak at 9, indicating very high levels of solar radiation. Forecasts suggest this area will see maximum temperatures of about 30 °C and minimums dropping to 4 °C. With little to no probability of rainfall expected for this week, residents are encouraged to stay hydrated and protected from sun exposure.
Detailed temperature expectations for March 8 indicate: highs of 40 to 45 °C for several states including San Luis Potosí and Guerrero; highs of 35 to 40 °C across regions like Jalisco, Michoacán, and Veracruz; and lows ranging from -15 to -10 °C within mountain regions of Chihuahua and Durango, potentially leading to frost.
The predictions highlight notable contrasts, with minimum temperatures of -5 to 0 °C expected across mountain ranges of Sonora and Zacatecas, alongside warmer ambient temperatures ranging from 0 to 5 °C for southern regions, such as Baja California Sur and Tamaulipas. During this bitterly cold phase, familiar cold safety measures have been reiterated by local authorities for the public's awareness.
It’s important for people living under these forecast conditions to stay alert to warnings and advisories from the SMN and local civil protection agencies. With trees and advertising signs potentially at risk due to strong winds, suitable precautions are highly recommended. It may also be wise to limit outdoor activities during hazardous wind conditions.
Residents are reminded to remain updated through official communication channels to receive timely weather alerts and understand the ever-evolving conditions brought by cold front 33 and its associated systems. Effective adherence to said advisories could minimize risks posed by sudden weather changes.
