Torrential storms lashing India and Nepal have killed hundreds of people since June, official data showed Tuesday, with flooding and landslides causing widespread devastation during the treacherous monsoon season.
The deaths include scores in India this month alone, and at least 171 overall in neighbouring Nepal.
Weather-related disasters are common during the monsoon season from June to September, but experts say climate change is increasing their frequency and severity.
In India, just months after the country baked in its longest-ever heatwave, according to government weather experts, ferocious rainstorms have triggered widespread flooding and landslides.
The crushing heatwave in May and June saw temperatures in New Delhi match the capital's previous record high: 49.2C (120.5F) clocked in 2022.
Now the heat has been replaced by rains.
India's weather department this week warned of "heavy rainfall" over much of the south and northeastern states.
On Tuesday, rescue teams searched for two missing people after nine drowned when a surge of water smashed through the Una district of Himachal Pradesh state.
"The search continues for the missing people," district official Shikha Rana told AFP.
Witnesses saw a car being swept away like a toy by the swollen muddy river.
"Several people tried to stop the car...as the current was increasing but the car sped past and soon the car was swept away by the strong current," Rajendra Kumar said.
In India's northern Uttar Pradesh state, at least 17 people have died in floods triggered by heavy rains since last week, official data said.
The usually hot deserts of Rajasthan have been swamped, with local media reporting at least 22 people killed in the floods since Sunday.
Surging waters in Uttarakhand have killed at least 51 people since June, according to state government figures.
And more than 200 people died in the southern state of Kerala last month, when landslides hit villages and tea plantations.
In Nepal, 171 people have died since monsoon rains began in mid-June, including 109 people in landslides.
Other deaths have been caused by floods and lightning, according to the disaster authority.
More than 40 people are missing, and over 200 have been injured.
Searches continue in central Nepal's Chitwan district for two busses swept over concrete crash barriers in a raging river on July 12, killing around 50 people.
Monsoon rains across the region from June to September offer respite from the summer heat and are crucial to replenishing water supplies.
They are also vital for agriculture, and therefore the livelihoods of millions of farmers and food security for South Asia's nearly two billion people.
India is the world's third-biggest emitter of greenhouse gases but has committed to achieve a net zero emissions economy by 2070 -- two decades after most of the industrialised West.
For now, it is overwhelmingly reliant on coal for power generation.
