Background on the National Weather Service (SMN) and its Role

The Servicio Meteorológico Nacional (SMN), Mexico’s National Weather Service, is responsible for monitoring weather conditions and providing timely warnings to protect lives and property. As part of the Comisión Nacional del Agua (Conagua), SMN plays a crucial role in ensuring the safety and well-being of Mexican citizens by tracking weather systems, including potential tropical cyclones.

Current Low-Pressure System and its Potential Development

SMN is currently keeping a close eye on a low-pressure area located approximately 660 kilometers southeast of the Suchiate River, on the border between Mexico and Guatemala. This system is associated with Tropical Wave 3 and is moving west-northwest.

According to SMN, there is a 60% probability that this low-pressure area will develop into a tropical cyclone within the next 48 hours. Furthermore, this probability could rise to 80% over the subsequent seven days.

Why this low-pressure system is significant

The development of a tropical cyclone in this region could have substantial impacts on Mexico’s southeastern states, particularly Chiapas. Such a system may bring heavy rainfall, strong winds, and potential flooding, affecting both urban and rural communities. Given the region’s vulnerability to natural disasters, close monitoring by SMN is essential for timely warnings and effective preparedness measures.

Conagua’s Monitoring and Preparedness

In response to the potential threat, Conagua and SMN will continue to monitor the low-pressure system’s evolution over the next seven days. This vigilance ensures that accurate forecasts and timely warnings can be issued to relevant authorities and the public, enabling them to take necessary precautions.
