On August 29, 2012, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image of Isaac over southern Louisiana at 12:15 p.m. Central Daylight Time (17:15 Universal Time). On the same day, the National Hurricane Center downgraded Hurricane Isaac to tropical storm status at 2:00 p.m. Central Daylight Time.
NASA is just days from launching an intensive multi-year study of hurricane formation and evolution in the Atlantic Ocean. Known as the Hurricane and Severe Storm Sentinel (HS3) mission, the project will use robotic Global Hawk airplanes to fly over and through storm systems. A principal goal is to learn more about what makes tropical storms intensify into hurricanes.
