Indian seas have two prominent cyclone seasons: Pre-Monsoon from March to May and Post-Monsoon from October to December. Though tropical storms have no official bounds as such and can form at any time of the year, the Bay of Bengal storms during the southwest monsoon season, which formally lasts from June to September, are not very common. The month of October is frequented by cyclonic storms on either side of the coastline: Bay of Bengal and Arabian Sea. In October 2025, two cyclonic storms, Shakhti and Montha, formed in the Indian Seas. In 2024, the Arabian Sea did find a storm in the month of August itself. The tropical storm ‘Asna’ travelled from the Gulf of Kutch to the Oman-Yemen Coast between 25th August and 02nd September 2024. Due to dry air entrainment, the storm got diffused over the sea itself, off the coast of Oman-Yemen.

The Bay of Bengal is hosting a storm in the month of September after five long years. Prior to this, tropical storm ‘Gulab’ had travelled across the East and Central Bay of Bengal to reach Coastal Andhra Pradesh on 26th Sep 2021. Gulab has a ‘twin storm’ history, and such combinations are rarely found over the Indian seas. The remnant of the Myanmar storm had entered the East Bay of Bengal across the Gulf of Martaban on 24th September 2021. It rapidly intensified into a cyclonic storm and had the distinction of being upgraded to a Cat-I storm, but quickly getting downgraded again back to a tropical storm on 25th September 2021. Finally, the cyclone tracked westward to cross the Andhra Coast near Kalingapatnam on 26th Sep 2021. It was downgraded after making landfall to a depression, which weakened further to a low-pressure area, moving across Telangana and Vidarbha.

The remnant of Gulab entered the Arabian Sea on 29th Sep 2021 and quickly intensified into another storm, this time named ‘Shaheen’. This storm intensified to develop a clear ‘eye’, a symbol of its strength. It kept moving away from the Gujarat Coast and made landfall over North Oman, making it one of the rare cyclones to strike that region. The storm caused devastating damage to the Oman and Iran region.

There is a prominent weather system developed over the Bay of Bengal. The National Weather Agency has restricted the strength of the weather system to a deep depression only. As per their predictions, it is unlikely to become a tropical storm and may make it to the coast as a deep depression. The Joint Typhoon Warning Center (JTWC) and CIMSS have both upgraded the system to a tropical storm, named 01B. As per the estimates, the storm is likely to cross North Coastal Andhra Pradesh, between Kakinada and Srikakulam, close to Vizianagaram, late tonight. Extremely heavy rainfall accompanied by very strong winds is likely to lash coastal parts of Andhra Pradesh and Odisha at the time of landfall. Inclement weather conditions are likely to persist over Andhra Pradesh, Odisha and Telangana for about the next four days. Rough weather conditions are expected over Vidarbha, East Madhya Pradesh, Chhattisgarh, Bihar, Jharkhand, West Bengal and East Uttar Pradesh during this week. Exercise utmost caution.
