Rio Guaíba nears flood‑alert level in Porto Alegre as waters keep rising
The water level of the Rio Guaíba in Porto Alegre rose to 2.51 m at the Cais Mauá monitoring station on 31 July and later recorded 2.54 m, approaching the flood‑alert threshold of 2.60 m. Authorities warn that the river could reach the critical flood level of 3 m if the rise continues. No extreme flood comparable to the historic May 2024 event is forecast for the coming days.
Tributary rivers – the Jacuí, Sinos, Gravataí, Taquari and Caí – are feeding the surge, and the state’s Civil Defence has issued an orange hydrological alert for the Guaíba. The alert covers vulnerable low‑lying neighborhoods, especially the Arquipélago islands.
Neighbouring towns are also feeling the impact: more than 100 residents remain displaced in Taquara, while roughly 1,000 people were affected in Rolante, with five temporary evacuations. The situation is being monitored continuously by the Defesa Civil, the Serviço Geológico do Brasil and local meteorological services.
