Fresh ‘low' in east to drive rains to north-west

The land-based and productive low-pressure area over west India has hardly weakened even as a counterpart ‘low' threw itself up fresh over Gangetic West Bengal on Thursday.
This fell in line with the observed pattern of ‘low's materialising over land even as the Bay waters mostly lay in trance right through the season.


India Meteorological Department (IMD) said in an update in the evening that the fore-runner of the ‘low's lay over southwest Rajasthan and adjoining south Pakistan.
It expected the Thursday's follow-up ‘low' over Gangetic West Bengal to become ‘well-marked' on Friday before being gobbled up by passing westerly system.
This is expected to become embedded into the monsoon trough, and global model suggested a west-northwest track for it towards northwest India.
While doing so, the system would be forced to keep within the confines of the corridor to the west-northwest and may not be made to tag the western disturbance to the east.


On its part, the monsoon trough straddled the two ‘low's (located respectively above Barmer in the west and Bankura in the east) and cut a path through Bharatpur, Fursatganj and Hazaribagh before being guided into east-central Bay of Bengal.
The offshore trough continued to run down from the Gujarat coast to the Kerala coast.
A weather warning issued by the IMD and valid for the next two days said that isolated heavy to very heavy rainfall would sustain over Gangetic West Bengal, Jharkhand, north Orissa, north Chhattisgarh, Uttar Pradesh and east Madhya Pradesh in east India and Saurashtra and Kutch in the west.
Isolated heavy rainfall has been forecast over the Jammu division of Jammu and Kashmir, Himachal Pradesh, Uttarakhand, coastal Karnataka, Kerala and Lakshadweep as well.


A short-term forecast IMD valid until Sunday said that widespread rain or thundershowers would occur over Gangetic West Bengal, Jharkhand, Orissa, Saurashtra and Kutch.
It would be fairly widespread over east Gujarat, the North-eastern States, northwest and central India and the remaining parts of east India as well as along the west coast.
Isolated rain or thundershowers may break out over interior parts of peninsular India.
A fresh circulation has blossomed over N.Bay and S. Bengal ... More showers will drive inland from East ..
