Forecasters predicted extreme fire conditions in southeastern Australia for the weekend of January 4–5, 2020, and they were correct in their assessment. The natural-color image above was acquired on January 4, 2020, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. Smoke has a tan color, while clouds are bright white. It is likely that some of the white patches above the smoke are pyrocumulonimbus clouds—clouds created by the convection and heat rising from a fire.
