Cold Front 30 Activates Winter Conditions Across Large Parts of Mexico
According to the latest 96-hour extended forecast by Mexico’s National Weather Service (SMN), Cold Front 30 will move over northeastern, eastern, and southeastern Mexico, interacting with a low-pressure system. This will cause a significant drop in temperatures and maintain very cold to freezing conditions across extensive areas of the national territory.
The associated Arctic air mass will favor morning fog banks and persistent winter conditions in northern and central states.
Intense Rains
One of the primary effects of this system will be an increase in precipitation, with heavy to very heavy and even torrential rains expected in Veracruz, Oaxaca, Chiapas, and Tabasco, where the highest accumulations are forecasted.
These rains could lead to river and stream level increases, landslides, waterlogging, and flooding in low-lying areas. Authorities are monitoring vulnerable regions for potential impacts.
North Event and Strong Winds
Cold Front 30’s advance will also generate another “North” event, with strong to intense winds along the Gulf of Mexico coast, the Yucatan Peninsula, and the Isthmus and Gulf of Tehuantepec.
Elevated sea conditions are expected along Veracruz, Tabasco, and Oaxaca coasts, potentially affecting maritime and port activities during this week’s start.
Extreme Cold, Frost, and Possible Snowfall
Very cold to freezing conditions will persist in northern and northwestern Mexico, with severe frost during mornings, especially in the mountainous regions of Chihuahua, Durango, Coahuila, Sonora, and Baja California. Temperatures may drop below -10°C.
The SMN does not rule out snow or sleet in the mountains of Sonora and Chihuahua, as well as on the summits of Cofre de Perote and Pico de Orizaba. States like Durango, Coahuila, Nuevo León, and San Luis Potosí face the risk of freezing rain, which increases the likelihood of road accidents.
How Will the Weather Be in the Valley of Mexico?
For the Valley of Mexico, including Mexico City, a cold environment is expected during mornings with minimum temperatures between 0 and 5°C, possible fog banks, and isolated showers accompanied by moderate wind gusts.
When Will Weather Conditions Improve?
By mid-week, Cold Front 30 will start to weaken and no longer directly affect the country. However, the SMN anticipates a new cold front could enter northwestern Mexico by Thursday, prolonging the cold conditions and snow or precipitation probability in that region.
Authorities advise exercising caution, staying informed through official channels, and following Protección Civil guidelines, particularly in areas prone to intense rains, strong winds, and low temperatures.
