TRMM Captured Category 4 Typhoon Melor Oct. 5 (IMAGE) NASA/Goddard Space Flight Center Caption TRMM captured Category 4 Typhoon Melor at 14:29 UTC on Oct. 5, 530 miles southeast of Okinawa. Melor had a nearly complete inner eyewall (the innermost bright green ring indicates moderate rain), surrounded by a nearly complete outer eyewall of moderate rain (wider concentric ring of bright green). This is only found in very powerful, mature tropical cyclones. The white area is a nearly symmetrical cirrus cloud shield indicating Melor was in a favorable environment..
