The Department of Hydrology and Meteorology has issued a high-alert for heavy rainfall and windstorms across Koshi, Bagmati, Gandaki, and Lumbini provinces, urging citizens to exercise extreme caution.

  • Heavy rainfall predicted for Himalayan, hilly, and Terai regions of Koshi, Bagmati, Gandaki, and Lumbini.
  • Windstorm alerts issued for Madhesh Province and Terai regions of multiple provinces.
  • Monsoon trough remains in its normal position, driving unstable weather patterns.
  • Authorities advise immediate caution in flood-prone and storm-risk zones.

The Department of Hydrology and Meteorology has sounded an alarm for Friday, forecasting severe windstorms across the southern plains and heavy precipitation across several provinces as the monsoon continues to exert its influence over the region.

According to the official forecast, heavy rainfall is expected at one or two locations within the Himalayan, hilly, and Terai regions of Koshi, Bagmati, and Gandaki provinces. Similarly, the hilly and Terai regions of Lumbini Province are expected to witness significant rainfall.

Why This Matters

BozokMedia analysis shows that the convergence of heavy rain and high-velocity windstorms in Nepal's diverse topography often leads to catastrophic landslides in the north and devastating flash floods in the south. This meteorological volatility poses a direct threat to the agricultural heartlands of the Terai and the critical transport arteries connecting the capital to the provinces.

"The alignment of the monsoon trough combined with localized atmospheric instability creates a high-risk environment for sudden meteorological disasters in the Himalayan foothills."

The department further anticipates generally cloudy conditions nationwide. During the night, heavy rainfall is predicted for the hilly and Terai regions of Bagmati, Gandaki, Lumbini, and Sudurpashchim provinces. In the high-altitude Himalayan regions, moderate rain or snowfall accompanied by thunderstorms is expected.

Regarding city-specific forecasts, Simara is expected to be the hottest, with temperatures peaking between 35–37°C. Dhangadi, Nepalgunj, Bhairahawa, and Dharan will follow closely at 34–36°C. In Kathmandu, temperatures are expected to range between 28–30°C, with a 60 percent probability of precipitation.

Did You Know?: Nepal's extreme altitudinal variation means the country can experience tropical heat in the Terai and sub-zero snowfall in the Himalayas simultaneously.
