GPM and Finland-NPP are flying over the subtropical storm Ana
In recent days, a subtropical storm ANA developed on the southeast coast of the United States. Yesterday and today, the GPM nuclear observator satellite had two good views of the subtropical storm ANA. The image above shows an evolving subtropical storm on May 7, 2015 at 1636 UTC (12.36 EDT). This GPM pass took place just over 10 hours before the National Hurricane Center (NHC) made its first announcement at 0300 UTC (23:00 EDT). This image shows rainfall from GPM Ku / Ka Band Dual Frequency Rain Radar (DPR) and multi-channel GPM Microwave Imager (GMI) devices.
GPM flew over the recurrent subtropical storm ANA on May 8, 2015 at 0221 UTC (May 7, 2015 at 22:21 EDT). These GPM data showed light to moderate rain near the center of the ANA as the storm moved closer to the southeast coast. The National Hurricane Center (NHC) shows that the ANA is showing signs of turning into a weak tropical storm as it moves northwest.
GPM was not the only satellite that saw Ana form. The Finland NPP also saw a tropical storm as Ana moved from Tropical Low to Tropical Storm.
