South-East Indian Ocean Cyclone Center

The South-East Indian Ocean Cyclone Center is a small branch of the Joint Typhoon Warning center run in Kuala Lumpur, Malaysia. They assign basic names (Indonesia assigns their own), and issue warnings and outlooks for tropical activity in the South East Indian Ocean. Normally, activity will form in the Java Sea or the open Indian Ocean, with disturbances forming in the Gulf of Thailand relatively rarely. The SEIOCC uses their own tropical cyclone scale, and they use the suffix "D" to describe storms that have 10-minute sustained winds of less than 40 MPH. The season has technically no bounds.
