THE RISK WINDOW

The Sep-21 red 'grande perigo' over about 699 municipalities has been downgraded as the Rio Grande do Sul coastal extratropical cyclone moves off toward open sea. The top alerts today are orange over Sao Paulo and its metropolitan region and over south-west Mato Grosso do Sul (Dourados), both for heavy rain and gusts past 100 km/h, with yellow over Volta Redonda and the Sul-Fluminense of Rio de Janeiro. The cumulative damage is about 2 dead, at least 15 injured and more than 140 municipalities across Rio Grande do Sul (98) and Santa Catarina (43), with hail striking about 80 percent of Tres Palmeiras. (Handled with care.)
