A new stage of the winter season is approaching in Mexico with the arrival of Cold Front Number 9, which entered through the northwest of the country and is expected to have a significant impact on a large part of the territory in the coming days. According to the National Meteorological Service (SMN), this cold front will extend from Baja California to Coahuila and Tamaulipas, affecting both temperatures and weather conditions.
What is a cold front?
A cold front is a meteorological boundary that separates a cold air mass from a warm air mass. When a cold front advances, the cold air mass displaces the warm air mass, which can lead to notable changes in weather conditions, such as drops in temperature, cloudiness, rain and strong winds.
The Advancement of the Cold Front in Mexico
The cold front began its incursion into Mexico on November 7 and its distribution pattern will clearly emerge in the coming days. The polar current will gradually extend from the northwest to the north and northeast of Mexico, triggering a series of notable climate effects. It is anticipated that the first impact will be felt in Baja California, particularly in its northern area, with noticeable effects starting November 9.
As the cold front advances, its influence will extend to states such as Sonora, Chihuahua, Sinaloa and Coahuila throughout the week, culminating in the phenomenon known as “Norte.” The “North” event will manifest strongly, generating adverse weather conditions in these regions.
The entry of this cold front in the northwest will mark the beginning of a week of significant climate changes in the north and northeast of Mexico. In addition, a dry line is expected to be established over northern Coahuila, which could cause strong gusts of wind and possible dust devils.
Frost on the Horizon
The arrival of this cold front leads to a marked decrease in temperatures, especially in the early hours of the day and during the afternoon in the northwestern and northern states of Mexico. In particular, “frosts” are forecast in the mountains of Baja California, Chihuahua and Durango, with minimum temperatures that will range between -5 and 0 degrees.
In other regions of the country, minimum temperatures are expected to fluctuate between 0 and 5 degrees in the mountains of Sonora, Hidalgo, State of Mexico, Tlaxcala and Puebla. These winter conditions will bring with them the need to take additional precautions to ensure the safety and well-being of the population.
Rains and Cold Fronts in the Winter Season
The arrival of Cold Front Number 9 marks the beginning of a promising winter season in Mexico. A total of 56 cold fronts are expected to occur throughout the season, extending from September 2023 to May 2024. For the month of November, five additional systems are expected to continue impacting temperatures and weather conditions. .
In addition to the cold conditions, rain is forecast in several regions of the country. It is anticipated that intervals of showers with heavy occasional rains will affect areas such as Guerrero, Oaxaca and Chiapas. In other areas, such as Baja California Sur, Chihuahua, Sinaloa and Durango, isolated rains are expected.
The interaction between these cold fronts and the entry of humidity from the Pacific Ocean will give rise to heavy occasional rains in Guerrero and showers in Puebla. The population is recommended to be alert and take the necessary measures to face these changing climatic conditions.
Temperature Changes Due to the Cold Front
In contrast to the cold conditions and rain, some states will experience warmer temperatures. In regions such as Baja California, Baja California Sur, Sonora, Coahuila, Nuevo León, Tamaulipas, Sinaloa, Nayarit, Jalisco and Colima, temperatures could range between 35 and 40 degrees Celsius.
In areas such as San Luis Potosí, Morelos, southwest Puebla, Veracruz and Tabasco, temperatures of 30 to 35 degrees Celsius are expected. Temperature variability across the country requires citizens to stay informed and take necessary precautions to deal with evolving weather conditions.
The arrival of Cold Front Number 9 is a reminder of the climatic diversity that characterizes Mexico and the importance of being prepared for changing winter conditions. Meteorological authorities will continue to monitor the development of this system and provide regular updates to ensure the safety and well-being of the population.
