The coastal extratropical cyclone did not wind down; it reached its peak under a red 'grande perigo' alert covering about 699 municipalities across the three southern states for the whole of today. The published thresholds are rain above 60 mm an hour or above 100 mm a day, gusts above 100 km/h, hail, and a tornado risk in parts of Parana, Santa Catarina and north-west Rio Grande do Sul. Four hazards on one alert is a staffing problem before it is a weather problem. Reached through national press desks rather than off the agency portal and marked reported for that reason; it is the Southern Hemisphere's headline today and the board's least-covered severe-weather story.

CONNECTED
One southern pattern change produced both alerts on the same day — and neither is read globally at anything like its severity.
The named storm gets the coverage and the unnamed cyclone gets the people.
