In an official note released by Mayor Tião Bocalom’s office this Tuesday afternoon (13), Rio Branco City Hall confirmed that the capital of Acre has entered a state of maximum alert. According to the 3pm measurement, the Acre River reached the mark of 13.30 meters, placing it just 20 centimeters from the alert level and 70 centimeters from the overflow level.

The scenario is worrying due to the behavior of the water source in the Alto Acre region. In the last few hours, records indicate that the river rose more than 4 meters in Assis Brasil and exceeded 2 meters in elevation in Brasiléia. According to Municipal Civil Defense technicians, this large volume of water is expected to hit the capital with force in the next 48 hours.
Faced with the imminent risk, Mayor Tião Bocalom called an emergency meeting with his entire secretariat. The meeting aims to align rapid response strategies and reinforce monitoring across the city.
“The capital of Acre is in a state of alert. A previous survey carried out by the Municipal Civil Defense indicates that the possibility of overflow in the coming days is considered high, due to the volume of rain and the accelerated rise in the river level.”
Municipal management guaranteed that Civil Defense is mobilized to monitor not only the local level, but also the rainfall in the headwaters that impact Rio Branco. A detailed assessment of the next measures to protect the population will be released soon.

Rio Branco City Hall informs that, according to the measurement carried out at 3pm this Monday, January 13, 2026, the level of the Acre River reached 13.30 meters in the capital of Acre, being just 20 centimeters from the alert level and 70 centimeters from the overflow level.
Recent data indicate a significant rise in river levels in municipalities in the Alto Acre region. In the last few hours, the Acre River rose by more than 2 meters in Brasiléia and more than 4 meters in Assis Brasil. According to the assessment of the technical teams of the Municipal Civil Defense Coordination, this behavior directly reflects the scenario observed in Rio Branco in the last 48 hours.
Given this context, the capital of Acre is on alert. A previous survey carried out by the Municipal Civil Defense indicates that the possibility of overflowing in the coming days is considered high, due to the volume of rain and the accelerated rise in the river level.
Out of concern for this scenario, Mayor Tião Bocalom called an emergency meeting with the entire municipal secretariat, with the aim of aligning actions, reinforcing monitoring and ensuring a prompt response from municipal management.
Rio Branco City Hall also informs that, as determined by Mayor Tião Bocalom, Civil Defense further reinforces monitoring of the level of the Acre River — also monitoring the level of rainfall in other regions, especially those that have a direct impact on the capital. In the coming hours, an updated assessment of the situation will be released, as well as the strategies and measures being adopted to ensure protection and care for the population.
Municipal management reinforces that it remains attentive, prepared and mobilized to act quickly, prioritizing the safety and well-being of Rio Branco families.
