In the North Indian Ocean's Bay of Bengal, Tropical Storm Phailin has formed off the west coast of Thailand, and is moving west-northwest towards India at 8 mph. Satellite images show that Phailin is a medium-sized storm that is increasing in organization and intensity. Water temperatures are warm, 28 - 29°C, and the ocean heat content is very high, 80 - 100 kJ/cm^2--a level often associated with rapid intensification. With wind shear low, Phailin should be able to intensify into at least a Category 1 storm before landfall occurs near 12 UTC on Saturday, as predicted by the Joint Typhoon Warning Center. The India Meteorological Department (IMD) is predicting that Phailin may be able to intensify into a Category 3 storm before landfall. The 12Z Wednesday run of the HWRF model predicted that Phailin would peak as a Category 3 storm with 125 mph winds at landfall on Saturday. The northeast coast of India where Phailin is expected to hit is vulnerable to high storm surges and is densely populated, so Phailin has the potential to be a very dangerous storm.

The cyclone hit the Indian state of Odisha (formerly called Orissa) near the city of Bhubaneswar as a Category 4 storm with 155 mph winds, killing 9,658 people and causing $2.5 billion in damage (1999 dollars).

India's tropical cyclone history
Only two Bay of Bengal tropical cyclones have hit India at hurricane strength since 2000. The most recent was Cyclone Thane,

Little change to 98L in the Eastern Atlantic
A tropical wave (Invest 98L) located about 400 miles south-southwest of the Cape Verde Islands is headed west to west-northwest at about 5 - 10 mph. Satellite loops show that 98L has a small area of heavy thunderstorms with a modest amount of spin. The UKMET and GFS models develop the disturbance into a tropical depression late in the week, but the European model does not. In their 8 am EDT Wednesday Tropical Weather Outlook, NHC gave the disturbance 2-day development odds of 30%, and 5-day odds of 40%. 98L's projected west-northwest track is expected take it near or just northeast of the Northern Lesser Antilles Islands around Wednesday October 16, according to the 00Z Wednesday morning runs of the GFS and European models.
Tropical Storm Nari headed towards the Philippines
In the Western Pacific, Tropical Storm Nari has formed east of the Philippines, and is expected to intensify into a Category 1 typhoon and make landfall on Luzon Island in the Philippines this weekend, and in Vietnam next week. The GFS and European models predict that a new tropical storm will form east of the Philippines late this week, but recurve to the northeast and not threaten any land areas.
