   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.
