India Meteorological Department (IMD) has declared that the southwest monsoon has withdrawn from parts of Punjab, Haryana, Rajasthan, Gujarat and north Arabian Sea on Friday.
The withdrawal line passed through Amritsar, Hissar, Ajmer, Deesa and Porbandar.
The western end of the monsoon trough is running close to the foothills of Himalayas, indicating weak or nil activity over northwest India.
DEPRESSION WEAKENS
The eastern end is still being kept active by Thursday's depression that has since weakened into a well-marked low-pressure system.
The eastern end passed through Gorakhpur, Daltongunj, centre of the low-pressure system (Jamshedpur) and Balasore before dipping southeastward into east-central Bay of Bengal.
The withdrawal process is now expected to run into residual monsoon activity over east and northeast India.
Interior peninsula too is forecast to be devoid of any major rain activity, though the east coast could witness some wet weather principally as an extension of the emerging storminess northwest Pacific and South China Sea.
PACIFIC DEPRESSION
True to forecasts, a monsoon depression has already sprung up afresh over northwest Pacific close to northeast Philippines.
Global models indicate the possibility of this system dropping anchor in the South China Sea basin where it would intensify into a tropical storm.
This is forecast to send in a ‘pulse' across Indochina into the Bay of Bengal to lit up the waters there and trigger rains along the southern Andhra Pradesh and Tamil Nadu coasts and into the peninsula.
WEATHER WARNING
A weather warning issued by the IMD said that the well-marked ‘low' over east India would trigger isolated heavy rainfall over east Uttar Pradesh, north Chhattisgarh, Jharkhand, Bihar, sub-Himalayan West Bengal, Sikkim, Assam and Meghalaya on Saturday and Sunday.
An extended forecast valid until Wednesday said that fairly widespread rain or thundershowers would break out over parts of east and northeast India.
The weather is expected to continue to remain mainly dry over many parts of northwest and adjoining central India.
