The Cuiabá Civil Defense has issued multiple alerts regarding severe weather conditions in the region. Initially, authorities focused on the risks of dehydration and heatstroke for infants and children due to high temperatures and dry weather, advising caregivers on hydration and sun exposure prevention.

By early November, the alerts expanded to cover a broader meteorological period involving intense heat, low humidity, and potential isolated storms. Forecasts indicated maximum temperatures reaching up to 40°C, with thermal sensations potentially hitting 45°C. While extreme heat was expected to persist, a shift toward more intense rainfall and lower temperatures was forecasted for the end of the period. Additionally, authorities noted that the Cuiabá and Coxipó rivers, along with the Manso Dam, remained in a state of drought with levels below attention thresholds.
