A fresh western disturbance is likely to cause enhanced rainfall over the western Himalayan region and adjoining plains during Sept 13-15.

PUNE: According to the India Meteorological Department (IMD), the withdrawal of monsoon may get delayed as moisture is still present due to the active monsoon current over North India. According to the IMD, enhanced rainfall activity is likely over Northeast and adjoining East India till September 13.

Dr DS Pai, Head, Climate Prediction at the Climate Research Division of IMD, Pune said as the southwest monsoon current still prevails over northern parts of the country, its withdrawal may take some time.

“Absence of moisture in the air is an indication of the monsoon withdrawal. However, in the past few days, there has been a strong monsoon current and Rajasthan witnessed rain. Later, the moisture moved north-northeastward,” said Pai.

On Monday, according to the IMD, the monsoon trough ran to the north of its normal position and its eastern end extends across the northeastern states. This situation is likely to prevail during the next three days. As a consequence, intense widespread rainfall is most likely over sub-Himalayan West Bengal and Sikkim, Arunachal Pradesh and Assam, Meghalaya.

According to the IMD, a fresh western disturbance is likely to cause enhanced rainfall over the western Himalayan region and adjoining plains during September 13-15.

Pai added that until these conditions subdue and there is no moisture in the air, the withdrawal will be delayed.

The southwest monsoon, as on Monday, has been subdued over Odisha, Uttar Pradesh, Uttarakhand, Jammu and Kashmir, east Madhya Pradesh, Gujarat State, Maharashtra and Goa.
