Porteirinha, a municipality in northern Minas Gerais, Brazil, has faced a critical situation following the increased risk of rupture of the Lajes water catchment dam. The local government declared a state of emergency on Sunday, October 1st, due to significant rainfall that raised concerns about the dam's structural integrity. Over 114 residents were evacuated from their homes, with some opting to stay in municipal shelters, while others found refuge with family members, declaring them as displaced persons.

The dam's instability comes after heavy rainfall in the region, with reports indicating that over 120 millimeters of rain fell within four hours, marking the most severe flooding event in over 40 years for the Lajes dam. This unprecedented weather event prompted regional authorities, including Inmet, to issue a red alert for the area, advising further precautions. The dam itself, covering 11 hectares and constructed in 1983, has reportedly experienced partial rupture, raising alarms about potential further disasters if conditions do not improve.

In response to the emergency, local officials are working closely with fire departments and other emergency services to mitigate risks and ensure the safety of the affected population. The situation remains fluid, with active monitoring of weather conditions and the dam's structural status indicating the communities involved need to remain vigilant. Plans for recovery and rebuilding will likely follow once the immediate risks are addressed, emphasizing the need for improved infrastructure in the wake of climate change and adverse weather patterns that contribute to such emergency situations.
