Severe Cyclonic Storm Remal

After four months of inactivity, on 21 May, the

(IMD) began monitoring a cyclonic circulation in the Bay of Bengal. Later that day, the

(JTWC) would also begin tracking the system, noting that it was likely to become a monsoon depression. The next day, the IMD noted that a low-pressure area had formed adjacent to the cyclonic circulation. Late on 23 May, the IMD upgraded the system into a well-marked low, stating that it was rapidly coalescing. The next day, the IMD stated that the depression formed in the Bay of Bengal, designating it as ''BOB 01''. Subsequently, the JTWC issued a

s. The next day, BOB 01 intensified into a deep depression. The JTWC would recognize the system as a cyclone, designating it as 01B. Soon after, the depression intensified into a cyclonic storm, causing the IMD to name it ''Remal''. On 26 May, Remal intensified into a severe cyclonic storm with 3-minute sustained winds of .

. The disturbance was later upgraded into a depression, designated as ''BOB 02''. The disturbance later moved inland, weakened back into a low-pressure area.

Deep Depression LAND 01

On 31 July, a cyclonic circulation formed over Gangetic West Bengal. Tracking westward, on 2 August, the disturbance developed into a depression. Two days later, it intensified further, becoming a deep depression over southwest Bihar. Tracking westward, on 5 August, the system weakened into a depression. It dissipated the next day.

Storm names

by mid-2020. There is no retirement of tropical cyclone names in this basin as the list of names is only scheduled to be used once before a new list of names is drawn up. Should a named tropical cyclone move into the basin from other basins, then it will retain its original name. The next eight available names from the List of North Indian Ocean storm names are below.
