Japan: Adverse winter weather forecast across northern regions through at least March 19

Adverse winter weather conditions are forecast across northern Japan through at least March 19. Heavy snowfall and strong winds are forecast in many areas and may cause blizzard conditions. Hazardous travel conditions are possible across parts of the country due to slippery roads and reduced visibility caused by blowing snow. Snow accumulations, de-icing operations, and reduced visibility may also lead to disruptions at airports in the worst affected areas.

As of March 18, the Japan Meteorological Agency (JMA) has issued the following weather warnings:

• Red snowstorm warnings (the middle level on a three-tier scale): western Akita, eastern Fukushima, Iwate, and Miyagi prefectures March 18.

• Yellow snowstorm, thunderstorm, gale, snow, dry air, and high wave warnings: the rest of the affected area through March 19.

Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.

In addition to the wintry precipitation, strong wind gusts could lead to periods of blowing and drifting snow. Sporadic power outages are possible throughout affected areas.

The winter weather may cause ground and air transport disruptions in the affected areas over the coming days. Traffic and commercial trucking delays are possible along regional highways. Difficult and potentially dangerous driving conditions are also possible on secondary and rural roadways in the affected states as maintenance crews prioritize clearing major routes. Authorities could close stretches of highway if driving conditions become too hazardous. Gusty winds may threaten to topple high-profile vehicles throughout the affected area. Flight delays and cancellations are possible due to ground stops and deicing operations at airports in the regions.
