Introduction

Mexico is bracing for a weekend of adverse weather conditions due to the interaction of several climatic systems, including Tropical Wave 2, a low-pressure area with high potential for cyclone development, and the ongoing heatwave. According to Mexico’s National Weather Service, these conditions will bring intense rainfall, strong winds, high waves, and temperatures exceeding 45°C in various regions from June 7 to 8.

Saturday: Intense Rainfall and Scorching Heat

On Saturday, June 7, a low-pressure area with potential cyclone development off the southern Pacific coast (interacting with the monsoon trough) will cause very heavy to intense rainfall in Guerrero, Oaxaca, and Chiapas. These precipitations will be accompanied by high waves (up to 4.5 meters) and wind gusts of up to 70 km/h along the coast.

  • Heavy rainfall is expected in Jalisco, Colima, Michoacán, Puebla, and Veracruz.
  • The central and northern regions will experience showers, winds, and possible waterspouts in eastern Chihuahua and northwestern Coahuila.

The heatwave will persist, with temperatures potentially surpassing 45°C in Sonora, Chihuahua (west and southwest), and Sinaloa (north). Records between 40 and 45°C are expected in Coahuila, Durango, Nayarit, Jalisco, Michoacán, Guerrero, and Campeche.

Sunday: Intensified Effects of the Cyclone

By Sunday, June 8, the low-pressure system is expected to strengthen into a potential tropical cyclone, moving parallel to the coasts of Michoacán, Colima, and Jalisco. Its associated cloud systems will increase the potential for very heavy to intense rainfall in Guerrero and Chiapas, as well as heavy rainfall in Oaxaca, Jalisco, Colima, and Michoacán.

The northern region will continue to be affected by a dry line and a low-pressure system, which combined with the subtropical jet stream and an approaching cold front, will generate strong winds, dust storms, and possible waterspouts or tornadoes in Coahuila.

The extreme heat will persist across much of the country. Temperatures are expected to exceed 45°C in Sonora and Chihuahua, and between 40 and 45°C in western, northeastern, and southeastern entities.

Recommendations

Authorities warn that intense rainfall could lead to landslides, sudden flooding, and river or stream overflows in vulnerable areas. Additionally, strong winds and high waves pose a risk along the southern Pacific coast.

Given the ongoing heatwave, it is advised to avoid prolonged sun exposure, stay hydrated, and take precautions against potential wildfires due to dry conditions and wind gusts.

The National Weather Service is closely monitoring the development of tropical systems and providing constant updates on any changes in their trajectory or intensity.
