The Reporting Platform and Voluntary Network of Severe Storm Observers, usually called PREVOTS, is a Brazilian group of meteorologists, which aims to improve documentation, research and forecasting of severe weather in Brazil. It began in June 2018 and is a combination of the Storm Observers Voluntary Network (REVOT) from the Federal University of Santa Maria and the Severe Weather Reporting Platform (PRETS).[1][2] PREVOTS is also a partner in an international collaboration that reports severe weather events in South America, the SAMHI.[3]
