Sistema Alerta Rio da Prefeitura do Rio de Janeiro

Alerta Rio is the alert system for heavy rains and landslides on slopes in the city of Rio de Janeiro. It was created on September 25, 1996 (Decree No. 15142) and since then has been managed by the GEO-RIO Foundation, with the aim of issuing ALERT BULLETINS to the population whenever there is a forecast of heavy rains that could lead to flooding of public roads and/or geotechnical accidents on slopes (slides). The System has a network of 33 telemetry stations spread across all regions of the Municipality of Rio de Janeiro. These stations send data in real time, every 15 minutes, to the Alerta Rio central. Of this total of 33 stations, 26 are pluviometric, that is, they only send rainfall readings. Five of them are meteorological stations that send rain, temperature and humidity readings (Irajá, Jardim Botânico, Barra/Riocentro, Santa Cruz and Alto da Boa Vista), and two are complete meteorological stations that transmit rain, wind, temperature, air humidity and atmospheric pressure data (Guaratiba and São Cristóvão). Learn more about the station network. The Alerta Rio/GEO-RIO team is made up of Meteorologists, Engineers, Geologists and Technicians who monitor weather conditions and maintain the equipment network 24 hours a day, 7 days a week. In situations where heavy rain is forecast for the Municipality of Rio de Janeiro, notices are issued to the City Hall bodies involved in mitigating the damage caused by heavy rain (such as Civil Defense, RioÁguas and others). The population is informed through the Alerta Rio channels on the Internet and through the press.
