Dolphin

Typhoon Dolphin battered and drenched the islands of Guam and Rota as it passed over the channel between them last Saturday. Luckily for Guam, Dolphin's most powerful winds occurred after passing to the northwest of Guam. By May 16, 2015 Dolphin had winds estimated at 140 kts (161 mph) making it a category five super typhoon on the Saffir-Simpson hurricane wind scale. The GPM core observatory satellite flew above the weakening typhoon early this morning when winds had dropped to less than 100 kts (115 mph). GPM's Microwave Imager (GMI) found that Dolphin was dropping rain over the open waters

Typhoon Dolphin passed through the Northern Marianas today just to the north of Guam with sustained winds estimated at 95 knots (~109 mph) by the Joint Typhoon Warning Center. The center passed through the Rota Channel less than about 25 iles from the northern tip of Guam, close enough for the southern half of the eye wall to rake the northern part of the island with powerful winds. A wind gust of 106 mph was reported at Andersen Air Force Base located on the northeast corner of Guam. NASA's GPM Core observatory satellite captured this image of Dolphin just as the center was exiting the Rota

Typhoon Dolphin formed south of Pohnpei in the western Pacific Ocean on May 7, 2015. Dolphin's power has oscillated from a weak tropical depression to typhoon intensity over the past five days. Dolphin is now an intensifying typhoon headed westward. The GPM core observatory satellite flew over Dolphin on May 12, 2015 at 2301 UTC. At that time Dolphin's wind speeds were estimated at about 65 kts (75 mph). Rainfall collected by GPM's Microwave Imager (GMI) showed that rain was falling at a rate of over 47 mm (1.9 inches) per hour in a feeder band to the southeast of Dolphin's eye. Ku Band data
