What Is the Fire Risk Warning About?

São Paulo's Civil Defense has issued an official alert warning residents about an elevated risk of wildfires as the state braces for a significant heat wave. Temperatures are forecast to climb up to 5°C above seasonal averages, creating dangerous conditions across the region.

Why Is This Combination So Dangerous?

Authorities are pointing to a perfect storm of three compounding factors: intense heat, low humidity levels, and dried-out vegetation.
