On October 19, an area of low pressure formed in the Bay of Bengal. During the next day, the India Meteorological Department (IMD) upgraded the area of low pressure to a depression giving it the designation BOB 04.

That day, the Joint Typhoon Warning Center (JTWC) designated the system as Tropical Cyclone 04B. Later, the deep depression strengthened further and was upgraded to a cyclonic storm and named Giri by the IMD. Early on October 22, the IMD upgraded the storm to a Very Severe Cyclonic Storm. The cyclone had intensified to a Category 4 tropical cyclone on the SSHS according to the JTWC. Late on the same day, the IMD reported that the system had grown stronger than Cyclone Phet, becoming the most powerful storm of the season. According to the news, the cyclone made landfall late on October 22, at Kyaukphyu, Arakan, Myanmar. Late on October 22, Giri weakened into a Severe Cyclonic Storm. Early on October 23, Giri further weakened into a Cyclonic Storm. Later the same day, Giri continued to weaken and became a depression. The depression continued to weaken until it decayed into a remnant low late on October 23. Early on October 24, the remnants of Giri were completely absorbed by a non-tropical low near the Himalayas.
