MTSAT-2 0.7 µm visible channel images (above; click image to play animation) and 10.8 µm IR channel images (below; click image to play animation) showed a close-up view of the small “pinhole eye” exhibited by Super Typhoon Utor east of the island of Luzon in the Philippines on 11 August 2013. On the following day, the eyewall of Utor made landfall on Luzon, but the storm had weakened somewhat at that point (to a Category 4 intensity), due to an ongoing eyewall replacement cycle — for more details, see the “From the Lee Side” blog post on Weather Undergrouund.
