Japan's weather officials warn of heavy rains, landslides

Japanese weather officials say heavy rains are expected in the Tohoku and Kanto-Koshin regions through late Monday due to extremely unstable atmospheric conditions. They are advising people to be careful of landslides and other disasters.

The Meteorological Agency says the unstable conditions are caused by colder-than-normal air flowing in at a high altitude in the eastern and northern parts of the country. Damp air flowing toward a low pressure system in the Sea of Japan is also a contributing factor.

The weather officials are advising people in the Kanto region to be alert for landslides even with a small amount of rain as Sunday's localized heavy rain already loosened the ground.

The officials are also calling for caution against flooding in low-lying areas and swollen rivers. They are also advising people to be alert for lightning strikes, gusts including tornadoes, localized heavy rain and hail.

People are advised to secure their safety by taking shelter in sturdy buildings when it suddenly becomes dark, cold winds start blowing and there is a sign of developed thunderclouds approaching.
