Travel through August: flash floods and landslides flagged in hill and river-valley routes

Travel advisories running through August flag flash floods, waterlogging and landslide risk across hilly and river-valley areas. City-based itineraries are being treated as the safer choice for the month.

What this means if you are travelling in the Northeast

The risk in this region is rarely the rain where you are standing. It is the rain upstream. A hill road can be dry and still be cut by a slip triggered by a cloudburst two valleys away, and a river valley can rise hours after the weather has cleared overhead.

Practical version:

• Check the route, not just the destination. A landslide closes a road for days, not hours.
• Build in a spare day. If a road closes, the cost is a delay rather than a stranded night.
• Do not attempt a flooded crossing in a vehicle. Six inches of moving water is enough to take a person off their feet; a car floats sooner than most drivers expect.
• Keep the tank above half in hill sections, since fuel stops close when roads do.

This runs alongside a monsoon that is below normal overall — fewer wet days, but heavier ones, which is the pattern that produces slips.
