The upper air cyclonic circulation over northwest Bay of Bengal deepened into a low-pressure area that persisted off the coast of Orissa and north Andhra Pradesh on Monday evening.
The ‘low' drove up rainfall activity over central and adjoining west India and along the west coast manifold to set up vigorous monsoon conditions during the 24 hours ending Monday morning.
MORE RAINS
An India Meteorological Department (IMD) outlook expected these conditions to continue for two more days.
Widespread rainfall occurred over Gangetic West Bengal, Maharashtra and Andaman and Nicobar Islands during the 24 hours ending Monday morning.
It was fairly widespread over Chhattisgarh, Jammu and Kashmir, Himachal Pradesh, Gujarat, Madhya Pradesh and coastal Karnataka. Scattered rain fell over Jharkhand, Orissa, interior Karnataka, Andhra Pradesh and Lakshadweep during this period.
WEATHER FORMATIONS
The rain-driving land-based monsoon trough passed through Jaisalmer, Banswara, Indore, Betul, Rajnandgaon and Puri before dipping southeastwards into east-central Bay of Bengal.
The offshore trough ran down from Gujarat coast to Kerala coast while a western disturbance kept guard over Jammu and Kashmir and neighbourhood. An extended outlook valid until Saturday said that the heavy rains would propagate further north into northwest, east and northeast India even as a let-up is seen over interior peninsular India.
WEATHER WARNING
A weather warning valid for the next two days said that heavy to very heavy rainfall would be unleashed at a few places over Konkan, Goa and south Gujarat. Isolated extremely heavy falls amounting to 25 cm or more is likely over north Konkan and south Gujarat. Isolated heavy to very heavy rainfall would also occur over Orissa and north coastal Andhra Pradesh during this period. Isolated heavy rainfall is likely over east Rajasthan, west Madhya Pradesh, north Gujarat, south Chhattisgarh and Telangana.
