The US Navy's Joint Typhoon Warning Center (JTWC) in Pearl Harbor, Hawaii, has said that Phailin is expected to break the Indian Ocean intensity record set by the 1999 Cyclone in which at least 9,000 people were killed in Odisha.
In its latest bulletin, JTWC said the extremely dangerous Tropical Cyclone Phailin has maintained Category five strength for six hours, and is expected to remain a Category 5 storm until it is just a few hours from landfall on the northeast coast of India on the Bay of Bengal.
While strengthening, the storm has grown to nearly half the size of India itself.
Jeff Masters, founder of Weather Underground in Ann Arbor, Michigan, wrote in his blog that he expects that Phailin will weaken slightly before hitting the coast, due to interaction with land, and hit as a Category 4 storm with winds of 145-155 mph. The 1999 Odisha Cyclone hit land with top winds of 155 mph.
