HAIDERABAD, India — Authorities said Tuesday that at least 33 people and five children in Pakistan have died in the past two days as a result of heavy monsoon rains and flooding in southern India.

In the Indian states of Andhra Pradesh and Telangana, houses collapsed and were washed away by heavy rains, and flooding disrupted road and rail traffic, officials said. The weather service issued a red alert for 11 districts, predicting more rain in the region, Telangana’s chief minister Shanta Kumari said.

More than 4,000 people have been shifted to 110 government relief camps in Telangana since Monday, according to the state’s top elected official, A. Revanth Reddy.

Overflowing lakes, reservoirs and streams have cut off access to some villages in Mahabubnagar and Nalgonda districts.

Vijayawada, the commercial capital of Andhra Pradesh, is grappling with its worst flooding in two decades, with the Budameru River submerging 40% of the city and stranding nearly 275,000 people in more than a dozen residential areas.

Disaster relief teams are struggling to transport stranded families to safer areas, Andhra Pradesh’s top elected official N. Chandrababu Naidu said.

At least 170 people have died in six northeastern Indian states since June in floods and mudslides triggered by rains, according to official figures.

In neighboring Pakistan, flash floods triggered by heavy monsoon rains killed five children in the southwestern province of Balochistan on Monday, bringing the total number of deaths related to heavy rains in the country since July 1 to at least 300.

Five deaths were reported in Zhob and Khuzdar districts, according to a statement by the disaster management authority. In Balochistan alone, floods have killed 32 people, including 18 children and 12 women, in the past two months.

Floods also inundated dozens of villages and blocked highways in parts of Balochistan and damaged nearly 20,000 houses across the country, mostly in Balochistan.

Landslide and flood disasters are common in both India and Pakistan during the monsoon season from June to September. Scientists and weather forecasters blame climate change for the heavy rainfall in recent years.

In 2022, climate change-induced torrential rains affected one-third of Pakistan’s territory, killing 1,739 people and causing $30 billion in damage.
