Meteorological authorities have issued a comprehensive weather alert for multiple regions across Mexico as a potent combination of weather systems converges over the nation. A cold front advancing across the Gulf of Mexico coastline is forecast to interact with a significant atmospheric river and an upper-level trough positioned over the Yucatan Peninsula, creating conditions for severe weather activity.
The most intense precipitation, featuring isolated torrential downpours reaching 75 to 150 millimeters, is projected to impact extensive areas including Veracruz (specifically the Huasteca Baja, Totonaca, Nautla, Papaloapan, Los Tuxtlas, and Olmeca regions), Puebla (Sierra Norte and Sierra Nororiental), alongside the states of Tamaulipas, Oaxaca, Chiapas, and Tabasco.
A secondary zone anticipating substantial rainfall between 50 to 75 millimeters encompasses Veracruz’s Huasteca Alta, Capital, Sotavento, and Las Montañas districts; Puebla’s Valle Serdan and Tehuacan-Sierra Negra areas; San Luis Potosi’s Huasteca region; multiple zones in Hidalgo including Huasteca, Sierra Alta, Sierra Baja, and Sierra de Tenango; and Queretaro’s Sierra Gorda.
Concurrently, an Arctic air mass accompanying this frontal system will trigger a dramatic temperature decline across northern, northeastern, eastern, and central Mexican territories. The system will also generate powerful northerly winds with heightened intensity along coastal Tamaulipas and Veracruz, extending to the Isthmus and Gulf of Tehuantepec regions, potentially creating hazardous marine conditions and wind impacts.
