These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
The scope of this article is limited to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula.
There are two main seas in the North Indian Ocean – the Arabian Sea to the west of the Indian subcontinent, abbreviated ARB by the India Meteorological Department (IMD); and the Bay of Bengal to the east, abbreviated BOB by the IMD.
Convection began to form around the center and a Tropical Cyclone Formation Alert was issued the next day by the JTWC.
Finally, on February 2, after the third TCFA was issued, the low pressure area developed into a tropical storm at 0900Z 370 nm west of Phuket, Thailand.
Shortly after peaking in intensity, vertical wind shear weakened the storm and the low became exposed by 1800Z the same day.
03B rapidly weakened due to vertical wind shear and the interaction with land and dissipated on June 11.
A depression formed in the northern Bay of Bengal on August 6 and moved inland into the Odisha state the next day.
On October 15, a developing area of low pressure, located 220 nm northwest of the Andaman Islands began to intensify.
The Prime Minister of India requested that relief supplies be distributed to the affected region immediately.
[6] On October 23, a Tropical Cyclone Formation Alert (TCFA) was issued by the JTWC for an area of low pressure in the South China Sea.
Later that day, the system reorganized and another TCFA was issued at 1930 UTC, with advisories for Tropical Cyclone 05B initiated early the next morning.
The storm tracked to the northwest and continued to intensify quickly; peaking as a 160 mph category five late on October 28.
11 hours after peaking, 05B weakened slightly to 155 mph and made landfall near the same area that 04B had only 11 days prior.
The storm slowly weakened as it stalled just onshore in Odisha, India while dumping torrential rains.
[8] The remnants of this storm from the Western Pacific basin entered the Andaman Sea on December 5 but redevelopment did not occur.
