Pre-monsoon showers lash Odisha
Bhubaneswar: Pre-monsoon showers brought relief from the scorching heat in most parts of Odisha on Saturday, according to the IMD. Heavy rain, along with thunderstorms, is likely across the State till May 30, and there will be no large change in temperature, it said. 'Almost all the districts experienced cloudy weather, with light to moderate rain at many places and heavy downpour in some areas,' said Manorama Mohanty, the Director of the Meteorological Centre in Bhubaneswar. 'Similar weather conditions are likely to prevail till May 30 in the wake of a cyclonic circulation that lies over north coastal Odisha,' she said. Between 8.30 am and 5.30 pm, Koraput received 45 mm rainfall, followed by Bhubaneswar (37 mm), Angul (36 mm), Khurda (22 mm) Cuttack (18.4 mm) and Talcher (12.4 mm). IMD scientist Umashankar Das said Odisha was receiving pre-monsoon rains after the southwest monsoon reached Kerala. 'The cloud systems responsible for the current rainfall are not moving in from the west or northwest, which is characteristic of Kalbaisakhi storms. Instead, these systems are advancing inland from the sea, a typical pre-monsoon pattern,' he said. The IMD advised people to take safe shelter during thunderstorm to protect themselves from lightning. The Centre for Environment and Climate (CEC) said the possibility of the formation of a low pressure area over the north-west Bay of Bengal may lead to the early onset of south-west monsoon over Odisha. The CEC Director, S C Sahu, said overcast conditions with light rain and thunderstorms were expected to occur over the State and rainfall was likely to increase from May 27 afternoon under the influence of the low pressure area. 'The rains may continue till May 30 night but heavy precipitation may occur on May 28 and 29 in the coastal belt of Odisha and a few other districts,' Sahu said. The intensity of rainfall may be too high in Mayurbhanj, Keonjhar, Balasore, Bhadrak, Jajpur, Dhenkanal, Sundargarh, Jagatsinghpur, Kendrapara, Puri and Khurda districts, he said. These rain-bearing systems may signal the onset of monsoon over Odisha on May 28 or 29, about two weeks before the normal date of arrival of the rains in the State, Sahu said. 'The rains occurring now may be termed as pre-monsoon rain with decreasing day temperature and increase in humidity,' he said.

Delhi rains: What is causing unseasonal storms, heavy rainfall in Delhi-NCR? IMD says reason is...
Delhi was lashed by unseasonal heavy rains and thunderstorms on Saturday. (ANI/File) Delhi rains: Delhi and its surrounding National Capital Region (NCR) was hit by pre-monsoon heavy rains, accompanied by gusty winds and thunderstorms that brought relief to people from the sweltering summer heat. However, such type of weather is not usually expected in the months of April to mid-May before the onset of monsoon. Then, what is causing these unseasonal storms and heavy rains in the Delhi-NCR region? The answer lies in the now undeniable climate change, which has caused the Kalabaisakhi or Nor'wester– a pre-monsoon phenomenon which is commonly associated with Eastern India, but has now presumably expanded to the Northern region due to changing climate patterns, according to weather agencies. What is a Nor'wester aka Kalabaisakhi? Locally known as Kalbaisakhi, a Nor'wester is a pre-monsoon phenomenon that usually occurs in Eastern parts of the country, bringing sudden heavy rains, accompanied by strong winds and severe thunderstorms in states like West Bengal, Odisha, Assam, Jharkhand, and Bihar, and some of parts of neighboring Bangladesh. The 'Nor'wester' is so named because storm usually moves from the northwest towards the east, while its local name 'Kalbaisakhi' loosely translates to 'calamity that strikes in the month of Baisakh (April-May). A Nor'wester or Kalbaisakhi storm is characterized by strong, powerful winds that can exceed 100 km/h, and move in a straight line akin to a Derecho– a wind pattern where winds move in a straight line unlike a Tornado, which is distinguished by its curly wind pattern. The pre-monsoon storm is often accompanied by sudden, heavy rainfall, which can trigger flash floods, akin to what was witnessed in Delhi-NCR on late Saturday night. What caused heavy rains, pre-monsoon storms in Delhi NCR? According to weather agencies, various weather phenomenon are responsible for Saturday's intense spell of heavy rains and thunderstorms in Delhi-NCR region such as western disturbances, which are low-pressure systems originating from the Mediterranean region that trigger unseasonal showers in north India, including the national capital. Additionally, upper cyclonic circulations over nearby over nearby regions like Haryana or Rajasthan, can lead to heavy rains and thunderstorms in Delhi-NCR. A recent spell of rains in Delhi-NCR is being attributed to this weather system. Apart from the above factors, other phenomenon such as convective systems, which are created by rapid upward movement of humid, moist air, can cause thunderstorms in Northern India. Further, the influence of monsoon trough starts increasing by late May when it moves south from its normal normal position, increasing moisture and contributing to stormy weather in the region.

Did an unlikely Kalbaisakhi hit Delhi on Sunday? What's behind unseasonal storm
Delhi-NCR has been occasionally experiencing heavy rain, accompanied by gusty winds and thunderstorms, for the past few days.

A Nor'wester, also known as Kalbaishakhi, is a severe thunderstorm that occurs primarily during the pre-monsoon season in April and May in Eastern India, normally in West Bengal, Odisha, Assam, Jharkhand, and Bihar, and also in term "Nor'wester" reflects the storm's typical movement from the northwest towards the east.

Residents grapple with heat, humidity amid weakened nor'wester impact
1 2 Bhubaneswar: Residents of the capital city have been grappling with intense heat and humidity for the past few days. Despite conditions being ideal for a thunderstorm, no such weather activity was reported in the period. By 8:30 am on Wednesday, Bhubaneswar recorded a temperature of 33.6 degrees Celsius with 62.3% humidity, taking the heat index (real feel) to around 42C. By 11:30 am, the city was sweltering at 37.4C with humidity dropping to 48.7%, yet the heat index peaked at a dangerous 46C. The measure of discomfort felt due to increased heat and humidity is known as the heat index, sources said. "Cities like Bhubaneswar, Cuttack and even Delhi and Kolkata are experiencing a new microclimate where urban heat islands , concrete expansion and loss of wetlands disrupt natural storm patterns," said Uma Shankar Das, weather scientist at IMD. Explaining the phenomenon in an X post, Das said, "The Kalbaisakhi or Nor'wester system is still active in the state, but its power diminishes drastically as it approaches the capital region. This is due to the dry, dust-laden, stable air layers hovering at 2-4 km height, which block vertical cloud development." The urban heat island effect creates localised high temperatures, altering air currents and storm behaviour, scientists said. It is disrupting both the intensity and path of thunderstorms, which may weaken, split or even bypass urban areas altogether. "I remember the summer storms a few years ago, which used to occur for a very short period with gusty wind, rain, and thunder, and that would suddenly cool down the entire city. Now, we wait endlessly for such relief," said Anuradha Sethi, a 58-year-old resident of Saheed Nagar. "The heat has become unbearable. It was impossible to stand outside for more than 10 minutes on Wednesday. The discomfort levels were very high with profuse sweating," said Tulika Panda, an MBA student. IMD has forecast an alert for rain and thundershower in 13 districts till May 25. "Several districts are witnessing rain and thundershower and temperature remained below normal. In coastal districts, moisture is being pulled from the Bay of Bengal leading to high humidity levels. In the capital city, the upper layer is dry while moisture is in the lower level, for which rainfall is not occurring," said Manorama Mohanty, director of IMD's regional centre here.
