The Servicio Meteorológico Nacional (SMN) and the Coordinación Nacional de Protección Civil (CNPC) have issued weather alerts for heavy rains and high temperatures [1, 2].

These conflicting weather patterns across the country pose significant risks to infrastructure and public health, as authorities prepare for potential flooding and heat-related stress.

Forecasters expect intense rainfall to hit Monterrey and the northeast of Mexico on Monday and Tuesday [1]. The weather shift is attributed to a surface trough that is creating atmospheric instability and encouraging heavy precipitation [1]. While some reports focus on the rain, other warnings indicate the possible formation of tornadoes in several states [2].

Simultaneously, the southern regions of the country are experiencing a different climate extreme. The SMN said that maximum temperatures in the south are expected to reach 37 °C [1].

Local authorities are monitoring the situation as the instability persists. While the primary alert for the northeast specifies rain through Tuesday [1], other reports suggest heavy rainfall could extend across various entities through Thursday [2]. The CNPC said it continues to coordinate with local emergency services to mitigate the impact of these weather events.

Maximum temperatures in the south are expected to reach 37 °C.

The simultaneous occurrence of extreme heat in the south and severe storm activity in the north highlights the volatility of Mexico's current atmospheric conditions. The presence of a surface trough creates a high-risk environment where rapid shifts from heavy rain to potential tornadic activity can occur, necessitating high levels of coordination between national meteorological services and civil protection agencies.
