NASA sees heavy rain in Tropical Cyclone Chan-Hom
The GPM core observatory satellite flew nearly above a newly formed tropical depression Chan-Hom (09W) on June 30, 2015 at 0841 (4:41 a.m. EDT). GPM's Microwave Imager (GMI) found that rain was falling at a rate of over 78 mm (about 3 inches) per hour near the center of the newly formed tropical cyclone.
GPM's Dual-Frequency Precipitation Radar (Ku Band) was able to measure rainfall to the west of Chan-Hom's center of circulation. At NASA's Goddard Space Flight Center in Greenbelt, Maryland, a 3-D image was created using GPM's Ku band radar data. The 3-D image showed storm tops reaching heights of about 15.1 km (9.3 miles) in a band of storms well to the southwest of Chan-Hom's center.
On July 1 at 0900 UTC (5 a.m. EDT), Chan-Hom was still a tropical storm with maximum sustained winds near 40 knots (46 mph/74 kph). Chan-Hom was centered near 10.8 North latitude and 155.5 East longitude, about 675 nautical miles (776 miles/ 1,250 km) east-southeast of Andersen Air Force Base. Andersen Air Force Base is located near Agafo Gumas in the U.S. territory of Guam.

The NWS in Tiyan, Guam issued this special weather statement on July 1: “The latest forecast brings a slowly-intensifying Chan-Hom toward the Marianas along a west to west-northwest track as it merges with a weaker circulation currently northwest of Chuuk.
Chan-Hom is expected to begin turning to the northwest and pass through the Marianas as a typhoon over the weekend. Showers and thunderstorms will develop across the Marianas Friday, July 3, and increase over the weekend. Periods of heavy rainfall are expected across the Marianas as Chan-Hom passes by. “
The Joint Typhoon Warning Center or JTWC expects Chan-hom to strengthen to a typhoon on July 2 after moving west and passing Fananu. JTWC also forecast the center of the typhoon to move very close to Guam on July 4.
