Pokhara sits in one of Nepal’s mid-hill valleys, where a milder climate than the Terai plains still receives the bulk of its rainfall during the June-to-September monsoon.
Nepal’s second city sits in a valley ringed by the Annapurna range, where intense monsoon rain funneled off the mountains can raise the Seti River very quickly. The Kathmandu Valley’s rapid, often unplanned urbanization has reduced natural drainage capacity, so intense monsoon downpours can cause serious urban flooding even though the valley’s rivers are relatively small, and radar helps track these fast-developing storms before they overwhelm city drainage.
