Typhoon Dolphin Weakening after Drenching Guam
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
