Its severity was confirmed on 16 May 2022 by the National Meteorological Institute (INMET) and the Brazilian Navy, which automatically classified it as an orange alert, meaning a subtropical storm.
[4] Winds of up to 100 km/h have been projected, and for this reason, both regional and federal civil defence had not denied the possibility of the cyclone turning into a hurricane as it moved towards land.
[8] On the 17 May, due to the intensity of the cold air mass that accompanied the cyclone, its humidity caused freezing rain and snowfall in the higher portions of southern Santa Catarina and Paraná.
[12] The cyclone began to lose intensity as it moved northeastward and when it turned eastward away from the coast of São Paulo it dissipated in late 19 May, according to the CHM synoptic chart.
In addition to the preparations of each state, the national civil defence was watching the storm situation with concern, thus already providing a number for emergency information via mobile phone.
[18] The civil defence together with the water and electricity companies were in a state of readiness to respond to possible calls that have already been programmed due to the strength of the storm.
[21] Another concern was with the geographical location of Florianópolis, given that it is an island bathed directly by the sea, which could reach waves up to 5 metres (16 ft) high with winds of up to 99 km/h on the coast.
[27] According to the Paraná System of Technology and Environmental Monitoring (Simepar), wind gusts were recorded with an intensity that exceeded 64 km/h (40 mph) on the coast of the state.
[26] Storm surge caused by the cyclone flooded several streets in the departments of Maldonado, mainly in the city of Punta del Este[28] and Rocha, as well as other locations in Canelones and Lavalleja.
