The Arabian Sea arm of monsoon hardly moved further from Monday’s coordinates of Harnai on the west coast and Solapur, Kalaburagi, Nandyal and Chennai in South Peninsula but the Bay of Bengal arm advanced the rains into remaining parts of North-Eastern states; entire Sikkim; and parts of hills of West Bengal on Tuesday. 

India Meteorological Department (IMD) said the Arabian Sea arm may not make significant progress on the west coast on Wednesday either in view of an incoming intruder western disturbance, while it may advance into more parts of Maharashtra; Karnataka; Telangana; Andhra Pradesh and remaining parts of Tamil Nadu. 

May will stay subdued

To the east, the Bay of Bengal arm is expected to make further progress in West Bengal; Chhattisgarh; Bihar; Jharkhand and Odisha during next 4-5 days thanks to strengthening flows. Monsoon is likely to stay subdued over many parts of the west coast where it has been most active during the week after its delayed onset. 

Mumbai was receiving light rain during the evening while it was comparably heavier Konkan-Goa; COastal Karnataka; and Kerala coasts. Moderate to heavy rain was being reported from elsewhere in the adjoining South Peninsula across North Interior Karnataka; Telangana; Rayalaseema; Andhra Pradesh; and Tamil Nadu. The incoming western disturbance will bring rain and thundershowers to North-West and Central India as well.

Western disturbance

According to the IMD, the intruder disturbance will affect the Himalayan region over next two days. A relatively weak successor is expected around Saturday and may persist until June 17.

As a result, the monsoon’s progress is likely to remain sluggish during this period, especially along the west coast. The European Centre for Medium-Range Weather Forecasts (ECMWF) indicates that this slowdown could begin as early as Thursday.

Heavy rainfall

Heavy rainfall on Wednesday is expected to be largely confined to the coastal belt from Panaji (Goa) through Karwar and Bhatkal to Mangaluru (Coastal Karnataka) and Kannur (Kerala). Thereafter, both the intensity and spatial extent of rainfall are likely to decrease progressively over the following days.

Forecasters are also monitoring signs of a circulation developing over the Bay of Bengal near the Andhra Pradesh–Odisha coast by June 22-23. If it materialises, it could provide fresh momentum for the monsoon’s advance into Central India, as also along the northern parts of the west coast.
