NASA's GPM observes newly formed Tropical Storm Georgette

On July 22, NASA/JAXA's GPM found extremely heavy rain (red) falling at a rate of over 224 mm (8.8 inches) per hour and cloud top heights over 14 km (8.7 miles) high in storms south of Georgette's center.As Tropical Storm Georgette was forming, the Global Precipitation Measurement mission or GPM core satellite flew overhead and gathered data that showed an intensifying storm.
