Brazil Issues New Weather Alerts as North Faces Flooding and South Braces for Fresh Cold Snap

Overview

• Inmet’s yellow alerts taking effect Friday cover every city in Paraíba and Rio Grande do Norte with forecasts of 20–30 mm an hour or up to 50 mm a day and wind gusts of 40–60 km/h.
• Cemaden and local Civil Defense kept Macapá on flood watch as canals risk overflow, with guidance citing bursts of 30–60 mm an hour or 50–100 mm in a day and plans for an orange alert if conditions worsen.
• Flooding already hit Amapá and Pará, with a river overflow in Tartarugalzinho displacing families, an igarapé in Mãe do Rio inundating streets and homes, and erosion partially closing the BR‑010 in Aurora do Pará.
• Forecasts call for a corridor of low pressure and new fronts to return rain to the Center‑South this weekend, then a continental polar air mass early next week that brings sharp cold and frost risk to southern highlands.
• Meteorologists link the northern rains to the Intertropical Convergence Zone, noting that short, intense downpours can overwhelm city drains and cut power, so residents are urged to avoid floodwaters and follow Civil Defense alerts.
