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.
As tropical storm Frank was forming in the Eastern Pacific Ocean, NASA analyzed rainfall and cloud heights and found "hot towers" that indicated intensification was likely.
The Global Precipitation Measurement mission or GPM core observatory satellite traveled above tropical storm Estelle and found heavy rainfall occurring on its eastern side. That heavy area of rainfall was later found west ...
The strongest sustained winds in the Eastern Pacific Ocean's Tropical Storm Estelle covered every quadrant of the storm except the southern area, according to data from NASA's SMAP satellite.
