At about 11 a.m. local time today, supertyphoon Rammasun was in the South China Sea not far from Hong Kong. Landsat 8 took this image of its eye as it was traveling west-northwest, toward Hainan and mainland China. In the eyewall – the windiest area, surrounding the relatively calm eye – there were gusts of about 250 km/h (150 mph). The eye itself is about 40 km (25 mi) across in this image, and huge wind-driven waves are just visible under its swirling low clouds. Rammasun has already passed over the Philippines, doing significant damage, and is now forecast to head inland along the China/Vietnam border. (via http://instagram.com/p/qmoV4sTeSD/)
