Overview and Key Person: The National Weather Service (SMN)
Starting Sunday and on Monday, December 15, Frigid Front 21 will bring heavy to very heavy rainfall, strong winds, and a significant temperature drop across extensive regions of the country. This weather system will move over Northeast Mexico and the Gulf of Mexico coast, interacting with a low-pressure channel. This interaction will result in intense rainfall in Northeast, East, and Southeast regions, with particularly heavy precipitation in Tamaulipas, Veracruz, and Chiapas.
Cold Air Mass and Its Impacts
The cold air mass linked to Front 21 will cause a notable temperature decrease in the North, Northeast, Central, East, and Southeast regions. Additionally, fog banks are expected in mountainous areas and high plains.
Strong Winds and High Waves
According to the National Weather Service (SMN), a “North” event will occur, with wind gusts reaching up to 90 kilometers per hour in the Isthmus and Gulf of Tehuantepec. Along the coasts of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatán, and Quintana Roo, wind gusts will be of lower intensity but accompanied by high waves, mainly in the Gulf of Mexico and Southeast regions.
These conditions may lead to navigation disruptions, fallen trees, and damage to outdoor advertisements and lightweight structures.
Monday: Intense Rainfall and Chilly Weather
On Monday, Frigid Front 21 will remain stationary over the Gulf of Mexico, prolonging very heavy to intense rainfall, especially in Veracruz. Precipitation is also expected in significant amounts in Puebla, Oaxaca, Tabasco, and Chiapas.
During mornings, cold to very cold conditions are forecasted with frost in mountainous areas of the northern and central regions. Diurnal temperatures, however, will vary greatly, with high values in Pacific and Southern states.
What to Expect in the Following Days?
Starting Tuesday, the frontal system will gradually move eastward across the Gulf of Mexico, reducing its impact on the country. Nevertheless, scattered showers and isolated rainfall will persist in various regions, along with cold nights and mornings, particularly in high-altitude areas.
The SMN warns that heavy rainfall may be accompanied by thunderstorms, rising river and stream levels, waterlogging, and flooding in low-lying areas. Therefore, the public is advised to stay vigilant regarding official alerts and exercise caution amidst adverse weather conditions.
