Brazil has experienced contrasting extreme weather conditions across different regions. In Roraima, a severe drought has caused water levels in the Branco River to drop significantly, with levels in Boa Vista falling 15 centimeters and Caracaraí falling 26 centimeters between October 12 and 19, 2026. The region has been under a state of emergency since early September due to rainfall levels reaching only approximately 28% of expected volumes in August.

Conversely, other areas have faced heavy rainfall and flooding. In Goiânia, storms produced up to 61.2 mm of rain, causing street flooding and fallen trees. In Querência do Norte, the Ivaí River rose by as much as 13 meters, isolating several communities and forcing residents to evacuate. The flooding has damaged rural roads and the PR-218 highway, leaving some families dependent on boats or tractors for access.
