Phuentsholing sits in Bhutan’s southern foothills near the Indian border, where a subtropical climate brings the country’s heaviest rainfall, driven by the same summer monsoon that floods the plains of neighboring India.
Bhutan’s main border town with India sits at the base of the Himalayas, where the Amo Chhu river and the foothills’ heavy monsoon rainfall combine to create the country’s most significant flood risk. Because the foothills sit right where monsoon-laden air from the Indian plains first meets the rising terrain of the Himalayas, rainfall totals here are dramatically higher than in Bhutan’s interior valleys, and radar helps track the intense storms that can trigger flash flooding on the steep slopes just above the border towns.
