Cold Front 4 Brings Intense Rainfall and Temperature Extremes Across Mexico
A stationary weather system triggers heavy precipitation in the north while heat persists elsewhere.
1Stationary Front Impacts
Cold Front 4 remains stationary over the Gulf of Mexico, interacting with a low-pressure channel in the east. This meteorological setup is driving intense rainfall across northern and northeastern regions. Authorities warn that precipitation levels between 75 and 150 millimeters could trigger dangerous flooding, river overflows, and localized landslides today.
2Regional Rainfall Distribution
The most severe downpours, ranging from 75 to 150 mm, are concentrated in northern Coahuila, Nuevo León, and Tamaulipas. Meanwhile, southern Veracruz, western Tabasco, eastern Oaxaca, and northwestern Chiapas face very heavy rains of 50 to 75 mm. These storms are frequently accompanied by electrical discharges, gusty winds, and potential hail.
3Northwestern Atmospheric Dynamics
Beyond the cold front, a cyclonic circulation in the mid-levels of the atmosphere and a subtropical jet stream are influencing the northwest. These systems are generating heavy rains in Chihuahua and scattered showers across Baja California Sur, Sinaloa, Durango, and Zacatecas, complicating the weather patterns across the western Mexican territory.
4Extreme Temperature Contrasts
Mexico is experiencing a sharp thermal divide. While northern mountainous areas in Chihuahua and Durango face freezing temperatures down to -5 degrees Celsius with frost, other regions remain hot. Southern Sonora, Sinaloa, Michoacán, Guerrero, Oaxaca, and coastal Chiapas are recording maximum temperatures between 35 and 40 degrees Celsius today.
5Valle de México Outlook
The Mexico City metropolitan area expects a morning of partial cloudiness and cool, misty conditions. By the afternoon, temperatures will rise to a range of 24 to 26 degrees Celsius. However, residents should prepare for potential afternoon showers and thunderstorms, accompanied by northern winds gusting up to 40 kilometers per hour.
6Highland Frost Risks
Beyond the primary cold zones, high-altitude regions in Baja California, Zacatecas, the State of Mexico, Tlaxcala, Puebla, Veracruz, and Oaxaca are bracing for minimum temperatures between 0 and 5 degrees Celsius. These areas are under advisory for potential frost, which could impact local agriculture and early morning road visibility conditions.
7Wind and Coastal Effects
Strong northern winds with gusts reaching 40 to 60 kilometers per hour are affecting the Isthmus and Gulf of Tehuantepec, specifically impacting Oaxaca and Chiapas. These wind patterns, combined with the influx of moisture from the Pacific, Gulf of Mexico, and Caribbean, are sustaining the heavy rainfall intensity across the country.
8Ongoing Weather Monitoring
The cold front is expected to remain stationary through Monday, continuing to influence the eastern and Gulf regions. Citizens are advised to monitor local road conditions and flood-prone areas closely. Meteorological authorities continue to track radar data to provide updates on the movement of these intense rain bands and storm systems.
