A subtropical cyclone that formed over southern Brazil heightened the storm risk on 20.
Storm warnings were issued for the entire state of Paraná, parts of Santa Catarina, and northern Rio Grande do Sul.
The warning concerns not only rain itself but also combined risks that could lead to strong winds, hail, and flooding.
3-Line Summary

2. Forecast of 30~60mm of rain per hour
3. Avoid taking shelter under trees
Storm Risk Warning Issued Across Paraná
Brazil’s National Institute of Meteorology (INMET) issued a storm risk warning on 20 for the entire state of Paraná, parts of Santa Catarina, and northern Rio Grande do Sul. Brazilian media outlet CNN Brasil reported that a subtropical cyclone passing through South America was affecting the formation of heavy rain in the region.
The forecast precipitation amounts were 30~60mm per hour or 50~100mm per day. The possibility of strong winds and hail was also mentioned. These figures show that the conditions could place strain on roads and drainage systems even over a short period, rather than becoming a problem only when rain continues for a long time.
The risks listed included power outages, crop damage, fallen trees, and flooding. G1 reported that, in the orange warning issued for Paraná on 19, winds could reach 60~100km/h, with risks of trees and branches falling or flooding occurring. The storm warning is guidance for conditions in which wind, lightning, and hail may occur simultaneously.
Unstable Weather Continuing from the Night of 20 Through 21
CNN Brasil reported that the warning level across Rio Grande do Sul could be raised to orange on the night of 20. A yellow potential-risk warning was applied to the rest of the southern region during some periods in the early morning and morning of that day. Clouds, rain, and thunderstorms were expected in Paraná, Santa Catarina, and Rio Grande do Sul on the same day.
Unstable weather is also expected to continue on 21. CNN Brasil reported that most of Paraná and Santa Catarina, as well as the entire state of Rio Grande do Sul, were subject to storm warnings. Terra reported that the cyclone would affect weather in southern Brazil even after moving over the Atlantic Ocean on 21.
The instructions issued by weather authorities are clear: Do not remain under trees when wind gusts occur, and, if possible, turn off electrical appliances and the household circuit breaker. People were also advised not to park vehicles near transmission towers or billboards. G1 reported that, during a disaster, help can be requested by calling Brazil’s Civil Defense number 199 or the fire department at 193.
The most important point in this warning is not the name cyclone but the combination of actual risks. Because heavy rain, wind gusts, hail, and lightning may overlap, people traveling or engaging in outdoor activities should first check the warning areas and guidance from authorities.
