Monsoon Alert: 30 Years' Data Warns of Heavy Rain

Danger is here, and it's falling fast

The Department of Hydrology and Meteorology (DHM) has issued a major warning based on 30 years of rainfall data: this year’s monsoon could bring unusually heavy rain, with serious risks of flooding, landslides, and waterlogging in multiple regions.

DHM experts say historical patterns and recent climate models point toward above-average rainfall from June to September. They’ve especially raised concern for vulnerable districts in the Terai, hills, and urban centers—all of which are already showing signs of saturated ground and rising water levels.

In major cities like Kathmandu, Pokhara, and Biratnagar, poor drainage systems could lead to flash floods and waterlogging, especially during peak rainfall hours. Meanwhile, hill districts such as Sindhupalchok, Baglung, and Rasuwa are at high risk for landslides, as constant rain weakens slopes and erodes already fragile land.

The Department of Hydrology and Meteorology emphasizes that climate change is amplifying the monsoon’s power. Rising global temperatures cause more moisture to build in the atmosphere, and when it rains—it pours. Combined with rapid urban development and deforestation, the effects can be catastrophic.

What to Expect and How to Prepare:
Local authorities are working with the DHM to update communities with regular weather forecasts and real-time alerts. Everyone is urged to take early precautions. These include:

• Keep emergency supplies (clean water, food, torch, first-aid) at home

• Store important documents in waterproof bags

• Avoid driving or walking through flooded roads

• Stay updated through DHM alerts or weather apps

• Know the nearest evacuation centers and safe routes

Schools and offices are advised to develop rainy day plans as sudden closures may be necessary. Transportation services may also face disruption due to submerged roads and landslide-blocked highways.

In flood-prone zones near rivers like the Koshi, Bagmati, and Narayani, families should be especially alert. The DHM warns that rivers may overflow if rainfall continues intensely for more than 72 hours, so monitoring river levels and evacuation notices is essential.

This isn’t just another rainy season—this is a call to be ready. With nature showing signs of an intense monsoon and science backing the warning, being prepared is the smartest move.

Keep your eyes on the skies—and your feet on higher ground.
