Heavy snowstorms are expected to blanket northern Japan and the Hokuriku region through Jan. 14 due to developing low-pressure systems and a strong winter pressure pattern.

The Japan Meteorological Agency is calling for the public to be vigilant about traffic disruptions and high waves.

According to the JMA, two low-pressure systems over the Sea of Japan and east of the Kanto region are expected to develop rapidly and approach Hokkaido on Jan. 12.

The strong winter pressure pattern, where high pressure lies to the west and low pressure to the east, is projected to continue until Jan. 14.

The agency forecasts maximum wind speeds of 90 kph for Hokkaido and the Tohoku region and 82.8 kph for the Hokuriku region lasting through Jan. 12.

The maximum wind speed for Jan. 13 is projected to reach anywhere from 72 to 86.4 kph for Hokkaido.

Some areas are expected to be walloped with snow. The amount of snowfall over the 24-hour period until 6 p.m. on Jan. 12 is projected to reach up to 70 centimeters for the Tohoku region, 60 cm for Hokkaido and the Hokuriku region, and 40 cm for the Kinki region.

Between 40 to 60 cm of snowfall is forecast over the 24-hour period until 6 p.m. on Jan. 13 for the Tohoku and Hokuriku regions, while Hokkaido and the Kinki region can expect anywhere from 30 to 50 cm.
