Active weather shifting base to east India


The ‘actively’ weather-making western disturbance is slowly moving away to the east of the country, which would be the focus of emerging weather over the next few days and into the weekend.
As this scene of action shifts to the east, there is a likelihood of a follow-up weakling system affecting the hills of the northwest where the India Meteorological Department (IMD) sees fresh scattered rains breaking out on Sunday.
Scattered rain or thundershowers would also occur over Kerala, Tamil Nadu, Andhra Pradesh, Orissa and the Northeastern States.
Meanwhile, an IMD weather alert said that heavy rain or snowfall is likely at isolated places over Jammu and Kashmir, Uttarakhand and Himachal Pradesh on Wednesday. Isolated thunder squalls or hail may occur over east Rajasthan, Haryana and Uttar Pradesh on Wednesday.
A weather update said that widespread rain or snow occurred over Jammu and Kashmir and Himachal Pradesh and fairly widespread over Uttarakhand during the day on Monday. Scattered rain or thundershowers was reported from Rajasthan, Punjab and Haryana and isolated over west Uttar Pradesh.
Maximum temperatures are above normal by 2 to 6 deg Celsius over central and adjoining east India.
Satellite cloud imagery on early Tuesday morning showed convective (rain-bearing) clouds over parts of Jammu and Kashmir, Uttarakhand Himachal Pradesh, east Rajasthan, Haryana, Delhi and west Uttar Pradesh.
The prevailing active western disturbance would continue to affect the western Himalayan region and plains of northwest India for the next two days and Gangetic plains and northeastern states from today (Tuesday) onwards.
Forecast valid until Friday said that fairly widespread rain or snowfall would occur over Jammu and Kashmir, Himachal Pradesh and Uttarakhand on Wednesday and decrease thereafter. Scattered rain or thundershowers would occur over east Rajasthan, Punjab, Haryana, Delhi and Uttar Pradesh on Wednesday and decrease thereafter.
Scattered rain or thundershowers would occur over sub-Himalayan West Bengal and Sikkim, Arunachal Pradesh and isolated over Bihar, Tamil Nadu and Kerala.
Maximum temperatures would fall over many parts of northwest India by 2 to 4 deg Celsius on Wednesday and Thursday as the westerly system fades away to the east.
Minimum temperatures, too, would fall by 2 to 4 deg Celsius over parts of northwest and adjoining central India during the next three days.
