Cyclones in the Pacific

Cyclones in the Pacific

The MODIS instrument onboard NASA's Aqua satellite captured this true-color image of Tropical Cyclones Olaf and Nancy in the South Pacific Ocean on February 16 at 1:10 UTC. At the time this image was taken, both cyclones were packing winds of up to 250 kmh (155 mph) and were buffeting the outlying islands of Samoa, American Samoa and the Cook islands, but had so far caused little damage and no injuries.

The centre of cyclone Olaf was about 150 kilometers (93 miles) northwest of Samoa's main island of Savai'i and was moving at 15 km an hour. The centre of cyclone Nancy, a category 3 storm, had already passed over the southern Cook Island atolls of Aitutaki and Mitiaro and was about 100 kilometers (62 miles) northeast of the main island of Rarotonga.
