monsoon-may-weaken-heatwave-to-intensify-imd

Large swathes of northwestern and eastern have already clocked temperatures significantly higher than normal for the past two or three days. Moreover, since June 1, there has been a 1 per cent deficiency in monsoon rainfall, with a 49 per cent deficiency over northwest India; 31 per cent over east and northeast India; 1 per cent over central India. Southern peninsular India, meanwhile, has recorded 69 per cent excess rain.

 

The progress of monsoon is likely to weaken over the next week and consequently intensify heatwave conditions over northwest and eastern India, meteorologists said on Tuesday.

 

“Models are not suggesting much rainfall, especially over north India over the next six or eight days. We cannot expect much rainfall over northwestern India now. This happens at times, and monsoon may pick up only by the end of June,” said M Rajeevan, meteorologist and former secretary of the Union ministry of earth sciences .

IMD however did not officially confirm that monsoon is weakening. “It’s too early to say when monsoon will reach the northwest,” said M Mohapatra, director general, IMD

 

“Monsoon progress over northwest India may be slow. Models predict below normal rainfall over northwest India in June. But we do not have the forecast immediately on how the monsoon will progress over the north,” Mohapatra had said on May 27.

 

The northern limit of monsoon is now passing through Navsari, Jalgaon, Amravati, Chandrapur, Bijapur, Sukma, Malkangiri, Vizianagaram and Islampur. Conditions are favourable for its further advance into some more parts of Odisha, coastal Andhra and northwest Bay of Bengal over the next three or four days.

 

Meanwhile, heatwave to severe conditions prevailed over several parts of Uttar Pradesh, in isolated pockets of south Bihar, Jharkhand, Gangetic West Bengal, Punjab, Haryana, Chandigarh, Delhi and in isolated pockets of Uttarakhand, north Rajasthan, Odisha and northeast Madhya Pradesh.

 

On Wednesday, heatwave conditions observed in most parts of Punjab, Haryana-Chandigarh-Delhi, Uttar Pradesh, Jharkhand; in many parts of north Rajasthan; in some parts of Himachal Pradesh, south Bihar, north Odisha and in isolated pockets of Gangetic West Bengal. Severe heatwave conditions also observed in isolated pockets of Uttarakhand, Himachal Pradesh, Punjab, Jharkhand & Gangetic West Bengal.

 

The maximum temperatures are in the range of 45-47°C over some parts of west Jharkhand, south Uttar Pradesh, Haryana-Chandigarh-Delhi, Punjab, north Rajasthan. The highest maximum temperature of 47.5°C is reported at Kanpur IAF (East Uttar Pradesh) over the country.

 

The weather office said heatwave to severe heatwave conditions are likely in parts of Uttar Pradesh till June 16 and over Gangetic West Bengal, Bihar and Jharkhand till June 14.

 

Heat wave conditions are very likely in isolated to some pockets of Uttarakhand, Punjab, Haryana, Chandigarh and Delhi over the next five days, northeast Madhya Pradesh, northwest Rajasthan till June 14; northeast Rajasthan, Himachal Pradesh, Jammu Division and Odisha on June 13.

 

IMD has issued a red category warning for Bihar on June 13, Jharkhand on June 13 and 14; East Uttar Pradesh till June 16, west Uttar Pradesh till June 16.

 

It has also issued an orange alert for Bihar on June 14; Jharkhand on June 15; Haryana-Chandigarh-Delhi, Punjab, Gangetic West Bengal on June 13.

 

A red category warning implies that local authorities need to act to prevent heat related emergencies. In red category warning areas, there is a very high likelihood of developing heat illness and heat stroke in all ages. Extreme care needed for vulnerable people, IMD has warned.
