Weekly Weather Forecast There is strong cold air in the south and cautious with heavy snowfall. It is hot from weekends to early week. Be careful with the dispersal of pollen.

Until around the 18th (Thursday), extremely strong cold air is expected to flow over the Japanese archipelago. Watch out for heavy snowfall in northern Japan, Hokuriku, and Sanin. More than 1m of snow is expected to accumulate on the Tohoku Sea side of Japan and in many places along the Hokuriku Mountains. Watch out for avalanches and falling snow.

Also, it can snow in western Japan, like Fukuoka, and it can accumulate in urban areas. There are expected to be times when snow clouds will flow into the Tokai region, such as Nagoya.

On weekends, it is widely covered with high pressure and there are many sunny spots mainly on the Pacific side west of Kanto.

It is expected to reach 15 ° C or more from 20 (Saturday) to 22 (Monday), 19 ° C in Tokyo and 17 ° C in Osaka and Nagoya on 21 (Sunday).

If the temperature rises, pollen will fly more easily, so if you have hay fever, take careful measures.
