      Extreme rains fell across northwestern Brazil in late March 2023,   
      causing flooding and triggering landslides. The torrential rain brought   
      at least 203 millimeters (8 inches) of rain in just three days to Rio   
      Branco, the capital of the Acre state. That’s 75 percent of the   
      rainfall expected in that area over the entire month of March.   
      
      According to ReliefWeb, as of March 30 about 15,000 people had been   
      displaced, and numerous homes and roads damaged. At least 172 of the   
      homes were destroyed in Manaus, the capital of the state of Amazonas.   
      The Negro and Solimões rivers meet just east of Manaus and join to form   
      the Amazon River. The Solimões River is also sometimes called the upper   
      Amazon River.   
      
      The Moderate Resolution Imaging Spectroradiometer (MODIS) on board   
      NASA’s Terra satellite acquired a false-color image centered on   
      Amazonas, Brazil on April 5, 2023, and a second false-color image of   
      the same area on December 25, 2022. Clicking on the dates under the   
      image will permit toggling back and forth between the two images, and   
      allow a comparison of the dramatic changes in the rivers of the region,   
      including the large Amazon River, between the two dates.   
      
      This type of false-color image, which uses MODIS bands 7, 2, and 1, is   
      often used to help separate water from surrounding vegetation or open   
      land. Water appears blue, vegetation is green, and open land is tan.   
      Clouds usually appear white, although high, cold clouds may carry a   
      tint of bright blue. The town of Coari sits near the center of this   
      image, close to where the bright blue waters of the Amazon River dips   
      southward. The darker water near that location are all flooded lakes.   
      
      Although the clouds were nearly-cloud free on April 5, when the most   
      recent image was acquired, thunderstorms are forecast from April 8-20.
