occasionally do, progress into the Indian Ocean or Central Pacific Regions.

SATELLITE

SATELLITES PROVIDE CONSTANT VISIBLE AND INFRARED (HEAT) IMAGES OF THE WESTERN PACIFIC. WE PREFER LINKING TO INFRARED IMAGES BECAUSE THEY ARE AVAILABLE DAY OR NIGHT AND PROVIDE CONTINUITY. WE ALSO PREFER SATELLITE IMAGES WITH LAND MAPS AND LINES OF LATITUDE AND LONGITUDE ADDED (MAPPED AND GRIDDED).
CURRENT INFRA-RED SATELLITE IMAGES ARE AVAILABLE 24 HOURS A DAY YEARLONG.
