Flash floods have passed, but Nepal is facing a crisis as infrastructure restoration and trade route reopening costs escalate amid fears of similar climate disasters recurring.

Two American tourists described how mountain floodwaters suddenly "poured down like a tsunami", sweeping away everything, and how they survived after their guide led them to higher ground.

Nepalese authorities warn of a new flood wave, urging residents in affected areas to remain highly vigilant.

Nepal states it currently does not require foreign rescue teams to search for flood victims, despite offers of assistance from numerous countries.
