BRAZIL — A ROUTINE SOUTHERN-STORM DAY: YELLOW CHUVA INTENSA FOR RIO DE JANEIRO STATE AND METRO AT 30 MM/H WITH WINDS TO 60 KM/H, PLUS BELO HORIZONTE; INTENSE AMAZON RAIN AND NO COLD WAVE

ACTIVE · September 15, 2026 · NO. 0915

THE RISK WINDOW

Carried, routine, and on the board because a quiet day checked is still a day checked. The national institute carries yellow chuva intensa for Sep 15 over Rio de Janeiro state and metro at 30 mm/h with winds to 60 km/h, and over Belo Horizonte; intense Amazon rain; low humidity across the central-north. No cold wave — the polar air that fed the last one is now Argentina's Wednesday problem, not Brazil's.
