New Delhi:

Heavy rainfall across large parts of India has compensated for the June deficit, bringing the overall monsoon precipitation into the surplus category.

According to the India Meteorological Department (IMD), more spells of heavy to very heavy rain are likely over northwest India and the western parts of the peninsular India during the next two-three days and over the northeast during the next five days.

India, the world’s top producer of critical crops such as rice, wheat and sugarcane, logged a rainfall deficit of 11 percent in June, with northwest India recording a shortfall of 33 per cent.

Heavy rain in the first week of July compensated for the shortfall but caused flooding in many northeastern states.

Since the four-month monsoon season began on June 1, the country has received 214.9 mm of rainfall against a normal of 213.3 mm, according to IMD data.

Northwest India and the southern peninsula have recorded 3 per cent and 13 per cent above-normal rainfall, respectively.

The heavy rain in the east and northeast region has reduced the deficit from 13 per cent on June 30 to zero on July 6.

The rainfall deficit in central India has decreased from 14 per cent to 6 per cent during this period.

The IMD data showed that 23 per cent of the sub-divisional area of the country experienced excess to large excess rainfall, 67 percent received normal rainfall, and only 10 per cent experienced deficient rainfall.

After making an early onset over Kerala and the northeastern region on May 30, and progressing normally up to Maharashtra, the monsoon lost momentum.

This delayed the rains in West Bengal, Jharkhand, Bihar, Uttar Pradesh, Chhattisgarh, and Madhya Pradesh and exacerbated the impact of a scorching heatwave in northwest India.

Monsoonal winds stalled from June 10 to June 18 and made slow progress until June 26-27. The annual rain-bearing system covered a major part of northwest India after June 25, according to IMD data.

The weather department on Saturday said heavy rainfall will continue in northeast India over the next five days.

The northeastern states are already grappling with severe floods.

Assam’s flood situation remains critical, with over 2.45 million people affected and 52 lives lost in the second wave of flooding this year.

Heavy rainfall in Manipur, Mizoram, and Arunachal Pradesh has caused rivers to reach warning levels and triggered landslides.

The IMD earlier this week said India could experience above-normal rainfall in July, and heavy rain may lead to floods in the hilly states and river basins in the central parts of the country.

Experts from the International Centre for Integrated Mountain Development (ICIMOD), a Nepal-based intergovernmental organisation, have also warned about a difficult monsoon season for the countries in the Hindukush Himalayan region, including Bangladesh, Bhutan, India, Nepal, and Pakistan.

IMD data shows that in 20 out of the 25 years when June rainfall was below normal (less than 92 percent of the long-period average), July rainfall was normal (94-106 percent of LPA) or above normal.

In 17 of the 25 years when June rainfall was below normal, the seasonal rainfall was normal or above normal, the IMD said.

New Delhi:

The torrential rain that brought Delhi to its knees last week was not a result of a cloudburst, the India Meteorological Department clarified on Monday.

Addressing a press conference, IMD chief Mrutyunjay Mohapatra said the Safdarjung Observatory, the city’s primary weather station, recorded 91 mm rainfall between 5 am and 6 am on June 28.

Similarly, the Lodhi Road weather station logged 64 mm from 5 am to 6 am and 89 mm from 6 am to 7 am.

“These do not warrant to be declared as cloudbursts, but it was very close to a cloudburst,” Mr Mohapatra said.

Explaining the reason behind the extreme weather event, the IMD had earlier said multiple large-scale monsoonal weather systems created conditions for mesoscale convective activity over Delhi NCR, resulting in intense thunderstorms and heavy rainfall during the early hours of June 28.

This activity was supported by thermodynamic instability in the atmosphere, which is favourable for thunderstorms.

The Safdarjung Observatory recorded 228.1 mm of rainfall in the 24 hours ending at 8.30 am on Friday, more than three times the June rainfall average of 74.1 mm and the highest for the month in 88 years — since 1936.

The IMD defines very heavy rain as rainfall amounting to between 124.5 and 244.4 mm in a day.

New Delhi:

The India Meteorological Department on Monday informed that Cyclone Remal over Coastal Bangladesh and adjoining Coastal West Bengal moved nearly northwards, with a speed of 15 kilometres per hour.

“The Cyclonic Storm ‘Remal’ over Coastal Bangladesh and adjoining Coastal West Bengal moved nearly northwards, with a speed of 15 kmph during the past 6 hours and lay centred at 08:30 hrs IST of today over the same region,” IMD posted on X.

According to the IMD, the severe cyclonic storm Remal has weakened into a cyclonic storm in the early hours of Monday and is expected to gradually weaken further.

“Severe Cyclonic Storm Remal over Coastal Bangladesh and adjoining Coastal West Bengal weakened into Cyclonic Storm at 0530hrs of the 27 May about 70km northeast of Canning and 30km west-southwest of Mongla. The system is likely to gradually weaken further,” IMD posted on X earlier.

Following the weakening of cyclone Remal, the flight operations resumed at Netaji Subhas Chandra Bose International Airport, Kolkata.

“Flight operations resumed at Netaji Subhas Chandra Bose International Airport, Kolkata at 0859 hrs, after it was closed for flight operation yesterday in view of the #CycloneRemal,” the official X handle of Kolkata Airport posted.

A passenger Debali Datta said, “I had my flight yesterday which got delayed. The airport authority informed me that it will depart today. This is because of the cyclone. Since we got to know beforehand, it did not create a lot of trouble for us.”

West Bengal Governor CV Ananda Bose with the Raj Bhavan task force also went on a field visit after cyclone Remal made landfall yesterday night.

“Raj Bhavan task force has just returned from the field visit. We are all greatly relieved that no reported casualty is there. Remal cyclone is weakening and the people of Bengal have been able to brave it with fortitude and courage. We are watching in case there is any need for any help. Raj Bhavan task force is ready. I thank the entire people of West Bengal for the solidarity which they have expressed,” Bose said.

Following the landfall of cyclonic storm ‘Remal’, waterlogging has been witnessed in parts of Kolkata with heavy rain.

Several trees were also uprooted in Kolkata’s Alipore area as heavy rain and gusty winds lashed several parts of West Bengal.

The IMD earlier informed that the storm ‘Remal’ would continue to move nearly northwards for some more time and then north-northeastwards and weaken gradually into a Cyclonic Storm.

The cyclone moved northwards and crossed the Bangladesh and adjoining West Bengal Coasts between Sagar Islands and Khepupara close to southwest of Mongla, said IMD.

“The Severe Cyclonic Storm ‘Remal’ over the North Bay of Bengal moved nearly northwards, with a speed of 13 kmph during past 06 hours, crossed Bangladesh and adjoining West Bengal Coasts between Sagar Islands and Khepupara close to southwest of Mongla near Latitude 21.75N and Longitude 89.2E between 22:30 hrs IST of 26th May to 00:30 hrs IST of 27th May 2024 as a Severe Cyclonic Storm with wind speed of 110 to 120 Kmph gusting to 135 Kmph,” said IMD in a post on X.

“It lay centred at 01:30 hrs IST of today, the 27th May, 2024 over Coastal Bangladesh and adjoining Coastal West Bengal, near latitude 21.9N and longitude 89,2E about 115 km east of Sagar Islands (West Bengal), 105 km west-southwest of Khepupara (Bangladesh), 70 km southeast of Canning (West Bengal) and SO km south-southwest of Mongla (Bangladesh), The system would continue to move nearly northwards for some more time and then north-northeastwards and weaken gradually into a Cyclonic Storm by morning of 27,” added the post.

The deep depression formed over the Bay of Bengal may intensify into a cyclone by Monday evening (October 23), the India Meteorological Department (IMD) said in a bulletin. The cyclonic storm, after its formation, will be called ‘Hamoon‘, a name given by Iran.

The system is currently located in west-central Bay of Bengal after moving northeastwards on Sunday night. It lies centred around 400 km from Odisha’s Paradip and 550 km south-southwest of Digha in West Bengal.

“It is likely to intensify into a cyclonic storm over the next 12 hours. It is very likely to move north-northeastwards and cross the Bangladesh coast between Khepupara and Chittagong around October 25 evening as a deep depression,” the IMD’s morning bulletin said.

Meanwhile, the Odisha government has asked all the district Collectors to remain prepared for any eventuality and directed the administration to evacuate people from low-lying areas in the event of heavy rain.

“The system (cyclone) will move in the sea around 200 km from Odisha coast,” weather scientist U.S. Dash said, adding that under its influence, light to moderate rainfall is likely at a few places in coastal Odisha on Monday and at many places over the next two days.

The Weather Department said that light to moderate rainfall would occur at a few places in northern and southern coastal districts, besides Keonjhar, Mayurbhanj and Dhenkanal. The Fisheries and Animal Resources Development Department has advised fishermen not to venture into deep seas.

Keeping in view of the weather conditions, Durga puja organisers are preparing for possible rain and wind during the festivities.

Watch | How climate change is affecting monsoon forecast and disaster management

From delayed onsets marked by intense dry spells, to devastating flash floods and destructive landslides, the monsoon in recent years has been a period of uncertainty and destruction for India.

Although there are various factors behind it, there is a general consensus among scientists that climate change plays a major role.

The Southwest monsoon that brings rain to the subcontinent during June and July, happens due to the heating up of the Asian landmass in the northern hemisphere during the scorching summer and the relative cooling of the southern Indian ocean.

How is climate change affecting monsoon? What are the challenges in predicting monsoons? Experts explain.
