Monsoon continues its journey amidst lack of cross-equatorial flow

0

New Delhi: The monsoon has managed to break out of a week-long stagnation after a timely onset in the extreme South-East Bay of Bengal. It is now expected to make further progress from midweek this week.

The northern limit of the monsoon lies along with the central parts of the Andaman and Nicobar Islands and is still good distance short from where it should have been in an ideal condition.

Indian Meteorological Department informed on Sunday that the unfavourable cross-equatorial flow over the Arabian Sea that aids in the progress of the monsoon is one of the reasons for its delay.

Monsoon has breached the Andaman and Nicobar Islands on May 18. But is yet to cover the entire region, added IMD in its statement.

IMD expected the monsoon to make further progress from Wednesday to Friday. Its week-long delay looks likely to be carried right until the onset over the mainland on the Kerala coast.

This is exactly what the IMD had forecast with respect to the expected date of June 6, which would be persisted with unless unexpected developments in the Arabian Sea.

Monsoon’s “bump” in the Arabian Sea

The monsoon flows are seen as running into a ‘bump’ from over the South-West Arabian Sea (equidistant from Kerala and the Somali-East Africa coast) and get disoriented.

Meanwhile, the IMD has forecast fairly widespread to widespread rainfall with isolated heavy falls over Assam & Meghalaya and the hills of Bengal and Sikkim on Wednesday and Thursday.

Scattered to fairly widespread rainfall (pre-monsoon) with isolated heavy falls is forecast over South Interior Karnataka until tomorrow (Tuesday) and over Tamil Nadu and Puducherry on Tuesday and Wednesday.

Heatwave conditions may persist over Vidarbha and at isolated pockets over Madhya Maharashtra, Telangana, East Madhya Pradesh, Chhattisgarh, East Uttar Pradesh, Jharkhand and Odisha until Thursday.
