When Hurricane Eugene was nearing its peak, NASA analyzed the storm's heavy rainfall over the open waters of the Eastern Pacific Ocean. That rainfall has lessened as Eugene has weakened to a tropical storm on July 11.
Hurricane Eugene formed on July 7, 2017, in the eastern Pacific Ocean south of the Baja Peninsula. On July 8 at 10:36 p.m. EDT (July 9 at 0236 UTC) the Global Precipitation Measurement mission or GPM core satellite passed over the storm and measured rainfall intensity.
