Heavy rainfall is anticipated across several regions of Chiapas,Mexico,with potential for significant impacts.You should prepare for substantial precipitation, notably in the northern and eastern parts of the state. Current forecasts, as of January 10, 2026, indicate accumulations between 75 and 150 millimeters in the North, Mezcalapa, De Los Bosques, Tulijá Tseltal Chol, and Maya regions.
Furthermore, very strong storms are expected to deliver 50 to 75 millimeters of rain in the Valles Zoque and Selva areas. I’ve found that these regions are particularly vulnerable to flash flooding during periods of intense rainfall, so vigilance is key.
Stronger, though less intense, showers are predicted for altos Tsotsil Tseltal, Meseta Comiteca Tojolabal, and Soconusco, with rainfall totals ranging from 25 to 50 millimeters. Elsewhere in the state, intermittent showers are likely.
Understanding the Weather System & potential Impacts
The arrival of the “Norte” weather system is bringing more than just rain; it’s also generating strong winds. Expect wind gusts between 60 and 70 kilometers per hour, and these speeds could increase to 90 kilometers per hour in the Istmo-Costa region. This is a significant change, and it’s significant to understand the risks.
These conditions necessitate caution, especially when traveling. Authorities recommend avoiding rural roads and trails due to reduced visibility and slippery conditions, which can lead to landslides or sudden surges of water. Here’s what works best: always check the latest weather updates before venturing out.
It’s also crucial to stay away from flooded areas, as submerged electrical cables pose a serious threat. Never approach downed power lines or attempt to cross rivers, streams, or low-lying areas during heavy rainfall.
According to the National Water Commission (CONAGUA), Chiapas experiences an average annual rainfall of over 3,000 millimeters, making it one of the wettest states in Mexico. This makes preparedness even more critical.
