Hokkaido is bracing for an unexpected return of winter conditions this week, with snow forecast to fall from May 4 to May 5. The timing coincides with the Golden Week holidays, raising concerns over travel disruptions and safety for both residents and tourists.
Cold Air Surge and Potential Accumulation
Forecasters indicate that strong cold air will flow over Hokkaido starting the afternoon of May 4. By the night of May 4, temperatures at approximately 1,500 meters are expected to drop below -6°C, particularly in regions along the Okhotsk Sea.
This level of cold is sufficient to produce snow on flat lands, where some accumulation is possible. Snow is expected to fall intermittently through May 5, with a risk of road freezing in high-altitude areas.
Infrastructure and Travel Risks
Authorities are warning that the expected wet snow may cling to trees and power lines, which could lead to power outages. Residents are encouraged to take preparatory measures against potential electricity failures.
The weather poses a significant risk to motorists, especially those who have already switched to normal tires or tourists visiting from outside the region. There is an increased danger of vehicles slipping or becoming stranded on the roads.
A Rare Visual Contrast
Despite the coming snow, spring has already arrived in several areas. On May 3, the bloom of Ezoyama-zakura was announced in Abashiri, arriving 7 days earlier than average and 5 days earlier than last year.
With blooms also announced in Wakkanai on May 1, there is a possibility that visitors may see the pale pink of cherry blossoms and white snow simultaneously.
Winter Driving Safety Guide
To navigate these conditions, safety experts suggest remembering the keyword “Fuyu-to-jiko”, which encapsulates five critical driving points:
- Equipment: Ensure winter tires are installed and carry tire chains. Check batteries and washer fluid, as batteries are more likely to fail in snow.
- Caution: Drive slowly. Be alert for “black ice” or frozen patches, even on familiar roads or areas that appear clear of snow.
- Alternatives: Consider detouring or postponing travel and adjusting driving plans.
- Timing: Depart with plenty of extra time to avoid the urge to speed on frozen roads.
- Information: Frequently check weather and road reports, as conditions can shift rapidly from sunny to snowy, potentially leading to road closures.
