INMET Issues 'Perigo' Storm Alerts for Southeast and Center‑West as Severe Cells Persist

Overview

• INMET upgraded parts of the Southeast and Center‑West to 'Perigo' on Saturday, June 13, warning of extreme short‑term rainfall and destructive wind gusts in affected areas.
• Forecasters cited possible rainfall rates of 30–60 mm per hour (with some forecasts up to 100 mm in 24 hours) and wind gusts of 60–100 km/h, conditions that raise the risk of flash flooding, landslides and power outages.
• The severe weather follows a cold front reinforced by an offshore low/cyclone and a moisture channel from the Amazon; the systems produced strong lightning and gusts in locations such as Campo Grande and prompted an orange alert in Porto Alegre.
• Municipal and state civil‑defense agencies remain on alert and are urging people to avoid flooded areas, not shelter under trees, disconnect electrical appliances and use emergency numbers (Defesa Civil 199, Bombeiros 193) if needed.
• NOAA’s confirmation that El Niño has re‑established gives wider seasonal context by increasing the chance of altered circulation and more frequent or intense rainfall episodes in the coming months.
