Abstract
Brazilians have great interest in weather forecasting, be it a trip plan, physical activity, the clothes that will go in the day or just for an elevator talk. There are several institutions and applications in Brazil and in the world that carry out the weather forecast, one of them being the Center for Weather Forecasting and Climate Research (CPTEC/INPE). One of these applications is the SOS CHUVA, developed by CPTEC, which shows images of radar and satellite in order to assist society in decision-making. The main goal of this work is to show the usability assessment performed in the SOS CHUVA app, in order to understand what aspects and user interfaces need improvement, in order to provide an even better product to society. For this, a usability assessment was made using the Thinking Aloud methods and the heuristic evaluation with the 10 Nielsen heuristics. Results are considered satisfactory showing the need for in-app adjustments.
