Many areas across Japan are expected to have unseasonably warm temperatures on Tuesday.
Officials of the Japan Meteorological Agency are calling on people in the quake-hit Noto Peninsula in central Japan to be careful of landslides because the ground has loosened.
The agency says a high pressure system will cover the archipelago, bringing an influx of warm air from the south.
Clear skies are forecast and the daytime high in Miyazaki City is expected to climb to 20 degrees Celsius.
The mercury in Fukuoka, Kagoshima and Nagasaki cities is expected to reach 18 degrees. A high of 17 degrees is forecast in Saitama, Shizuoka, Matsuyama and Toyama cities. It's expected to be 16 degrees in central Tokyo and Osaka City, 15 degrees in Sendai and 10 degrees in Sapporo.
Officials say the temperatures across the country will be especially high for this time of year until Wednesday.
They say the difference in temperatures in the morning and at night will be large, and snow will melt in areas that have had precipitation. They are calling on people to be careful of their health and be cautious of falling snow from rooftops and avalanches.
