Damage from Phailin
Phailin is the strongest tropical cyclone to affect India in fourteen years, since the great 1999 Odisha Cyclone. That storm hit with maximum sustained winds of 155 mph, and brought a storm surge of 5.9 meters (19 feet) to the coast. Phailin should be able to drive a similar-sized storm surge to the coast, since it is larger in areal extent than the 1999 cyclone (although somewhat weaker, with winds perhaps 20 - 30 mph lower.) Phailin's storm surge and Category 3 to 4 winds will cause near-catastrophic damage to a 50-mile wide swath of the coast where the eyewall comes ashore, and to the right. Hurricane Katrina was weaker at landfall than Phailin, but Katrina had hurricane-force winds that covered a much larger area, making Katrina's storm surge much more devastating than Phailin's will be. I think the main danger from Phailin will be from its winds. I am particularly concerned about Phailin's wind damage potential in the city of Brahmapur (population 350,000), the 58th largest city in India. Brahmapur lies about ten miles inland, and will likely experience sustained hurricane-force winds for several hours. Phailin's flooding potential is another huge concern, as rainfall amounts of 6 - 12 inches will fall along a swath over 100 miles inland, triggering life-threatening flash flooding.
Typhoon Nari hits the Philippines
Thirteen people were killed and 2.1 million people lost power on the main Philippine island of Luzon afterTyphoon Nari hit on Friday night near midnight local time. Nari was a Category 3 typhoon with 115 mph winds a few hours before landfall. The core of the storm passed about 80 miles north of the capital of Manila, sparing the capital major flooding, but the storm dumped torrential rains in excess of ten inches to the northeast of Manilla. Passage over Luzon weakened Nari to a Category 1 storm, but it is already beginning to re-organize over the South China Sea between the Philippines and Vietnam. Nari is under moderate wind shear of 15 - 20 knots, which should keep intensification relatively slow, and increasing interaction with land will act to slow intensification on Sunday and Monday. Nari could be near Category 3 strength with 115 mph winds by Monday, and landfall in Vietnam is expected around 21 UTC on Monday.
