Heavy Rains and “North” Event in Southeastern Mexico
This weekend, May 10th and 11th, Mexico will face extreme weather conditions due to the combination of Cold Front 42 and a persistent heatwave, according to the National Weather Service (SMN).
- Heavy rainfall (150 to 250 mm) is expected in southeastern states like Chiapas, Tabasco, Yucatan, and Quintana Roo due to the interaction of Cold Front 42 with low-pressure channels.
- Intense rainfall is also anticipated in Veracruz, Oaxaca, and Campeche, along with very heavy rainfall in Guerrero and central Mexico.
- These precipitations may be accompanied by thunderstorms, hail, and potential landslides or flooding in low-lying areas.
- The cold front also triggers a “North” event, causing wind gusts of up to 90 km/h in the Isthmus and Tehuantepec Gulf, as well as strong winds along the coasts of Veracruz, Tabasco, Campeche, and Yucatan. Elevated wave heights of 2.5 to 3.5 meters are expected along the Gulf and southern Pacific coasts.
Temperature Drop in Large Parts of the Country
As the cold air mass associated with Cold Front 42 advances, a decrease in daily temperatures is expected in northern, central, eastern, and southeastern regions of Mexico. In high-altitude areas of states like Durango, Chihuahua, Zacatecas, and the State of Mexico, minimum temperatures could drop below 5 °C during Sunday morning.
Heatwave Continues in Northwestern, Western, and Southern Regions
In contrast, high-altitude anticyclone circulation will maintain a hot to extremely hot environment in northwestern, western, and southern states like Baja California, Sonora, Sinaloa, Nayarit, Jalisco, Michoacán, and Guerrero, with maximum temperatures ranging from 40 to 45 °C. The heatwave will also extend to Chihuahua, Durango, Colima, and Oaxaca.
By Sunday, the cold front is expected to continue affecting southeastern Mexico and the Yucatan Peninsula, while temperatures are projected to rise again in central and northern regions from Monday due to the thermal modification of the cold air mass.
Safety Recommendations from SMN
The National Weather Service (SMN) advises the public to stay informed through official channels, avoid crossing swollen rivers or streams, secure objects that could be carried away by the wind, and exercise caution against heat in affected thermal regions.
