Himalayan region to experience hotter summer, more rain, says ICIMOD

Temperatures are expected to be two degrees Celsius higher than average across the whole Hindu Kush Himalayan region this summer, according to a new analysis by the International Centre for Integrated Mountain Development (ICIMOD).
The ICIMOD also predicted that India, Nepal, Pakistan as well as China's Tibetan Autonomous Region will receive above-average rainfall.
With floods the leading cause of deaths and economic damage in the Hindu Kush Himalayan (HKH) region, and close to three-quarters (72.5 per cent) of all floods from 1980 to 2024 occurring during the summer monsoon season, experts warn disaster agencies and communities to be prepared for a possible rise in climate risks.
The forecasts we've studied are unanimous in predicting a hotter monsoon across the entire HKH, with a trend towards higher-than-normal rainfall in major parts of the region, Arun Bhakta Shrestha, senior advisor at ICIMOD, said.
Rising temperatures and more extreme rain raise the risk of water-induced disasters such as floods, landslides, and debris flows, and have longer-term impacts on glaciers, snow reserves, and permafrost, a press release issued by the ICIMOD said.
Lower rainfall, meanwhile, particularly in water-stressed countries such as Afghanistan, may pose risks to food and water security in a country with already extraordinarily high levels of malnutrition, it added.
Given the extremely high exposure and risks in our region, we urgently need impact-based early warning systems adopted at scale, and for government and donor support to build up disaster preparedness to increase, said Saswata Sanyal, manager of ICIMOD's Disaster Risk Reduction work.
Climate change by driving more intense rainfall, permafrost degradation, and glacier retreat that can trigger floods, landslides, and glacial lake outburst floods is the primary cause of the increasing frequency and magnitude of mountain hazards in the HKH region, states the ICIMOD report.
Rise in temperature combined with wetter monsoons can also raise the risk of heat stress and waterborne disease outbreaks, such as dengue, warn experts.
We know that worldwide, monitoring and prediction are playing an increasingly powerful role in safeguarding people and economic activity from rising climate risks, said Sarthak Shrestha, remote-sensing and geo-information associate at ICIMOD.
In its country-wise forecasts, the ICIMOD has stated that in India, there is a strong probability that southwest monsoon seasonal precipitation will be above normal.
For Nepal, it predicts above normal precipitation and both minimum and maximum temperatures are forecast to be above long-term averages.

Weatherman predicts light to moderate rain for next 3 days

Lucknow: A cloudy day with a few spells of light rain gave relief to people from high temperatures. However, high humidity levels led to some discomfort, but the absence of the sun throughout the day kept the maximum temperatures low. According to the weatherman, there is a warning of lightning and thunderstorms in the next three days when the city is likely to experience light to moderate rains due to low-pressure system in central Uttar Pradesh and a trough line crossing from Punjab to the Bay of Bengal. On Sunday, the maximum temperature was 33.9 degrees Celsius, which was 3.5 degrees below normal, and the minimum temperature was 26.6 degrees Celsius. Senior scientist Mohammad Danish said that on Monday it will be a partly cloudy sky, becoming generally cloudy with one or two spells of rain/thundershowers. The maximum and minimum temperatures will be around 33 and 26 degrees Celsius, respectively. Meanwhile, in the state, there is a forecast of rain/thundershowers very likely at many places over west Uttar Pradesh and a few places over east Uttar Pradesh. There is a warning of thunderstorms accompanied by lightning very likely at isolated places, and heavy rain is very likely at isolated places over the state. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 5 Books Warren Buffett Wants You to Read In 2025 Blinkist: Warren Buffett's Reading List Undo Lucknow: A cloudy day with a few spells of light rain gave relief to people from high temperatures.
