NASA analyzes rainfall around Typhoon Chan-hom's ragged eye
On Oct. 7 at 2 a.m. EDT (0600 UTC), NASA’s IMERG estimated Typhoon Chan-hom was generating as much as (30 mm/1.18 inches of rain (dark pink) around the center of circulation. Rainfall throughout most of the storm was occurring between 5 and 15 mm (0.2 to 0.6 inches/yellow and green colors) per hour. The rainfall data was overlaid on infrared imagery from NOAA’s GOES-16 satellite. Credit: NASA/NOAA/NRL

A NASA satellite rainfall product that incorporates data from satellites and observations found heavy rainfall occurring throughout Typhoon Chan-hom and the heaviest rainfall in the eyewall. Chan-hom is expected to bring rainfall to Japan on its track through the Northwestern Pacific Ocean.

NASA’s Terra satellite obtained visible imagery of Tropical Storm Chan-hom as it continued moving though the Northwestern Pacific Ocean. The imagery revealed that the center of circulation was exposed and its strongest storms were south of the center.


Tropical Depression 16W formed on Oct. 4 and strengthened into a tropical storm on Oct 5. Once it reached tropical storm strength, it was re-named Chan-hom. Laos submitted the name Chan-hom to the World Meteorological Organization list. The name is a type of tree in Laos.
