De acordo com o Instituto Nacional de Meteorologia, o estado mais afetado é o Rio Grande do Sul, onde há risco de tempo severo, com temporais, chuva intensa, rajadas de vento, descargas elétricas e eventual queda de granizo. A previsão do tempo indica acumulados de chuva que podem ultrapassar 100 mm no estado vizinho.

Santa Catarina entra na área de influência do sistema, conforme o Inmet, com instabilidades e temporais isolados, principalmente entre a tarde de segunda-feira (20) e ao longo de terça-feira (21), feriado.
