An overpass of the NOAA-17 satellite occurred at 17:33 UTC on 04 June; the IR image (below)<\/strong><\/em> depicted a detailed radial “banded structure” to the cold brightness temperature field, with a minimum temperature of -89\u00ba C (darker purple enhancement)<\/em>. Also note the area of concentric gravity waves south of the eye (within the gray-to-white enhanced area of -75\u00ba to -79\u00ba C brightness temperatures).<\/p>\n

This was the first tropical cyclone of Category 5 strength on record in the Arabian Sea.<\/p>\n
