Rough weather forecast across Japan

Weather officials are warning of rough weather across Japan due to a rapidly growing low-pressure system accompanying a cold front in the Sea of Japan.

Japan's Meteorological Agency is calling for caution against flooding in low-lying areas, mudslides, swollen rivers, gusts, lightning strikes, and hail. Weather officials are also warning people in northern Japan and some other areas of windstorms and high waves.

A cold front around the Tsushima Strait in western Japan is bringing rain clouds to the Kinki and Tokai regions on Monday morning.

From 8 a.m. to 9 a.m., 22 millimeters of rain fell in Hidakagawa Town in Wakayama Prefecture. Toba City in Mie Prefecture had 21 millimeters.

Weather officials are predicting more than 30 millimeters of rainfall per hour in wide areas across Japan from Kyushu to Hokkaido.

They say some areas along the Pacific Ocean in Hokkaido may get as much as 150 millimeters of rain in the 24 hours through Tuesday morning.
In the same period, 120 millimeters of rain is expected in some areas of the Kanto region, the Izu Islands and the Tokai region. Up to 100 millimeters is expected in some areas along the Pacific coast of the Tohoku region.

The low-pressure system in the Sea of Japan is expected to develop rapidly and bring windstorms to northern Japan and other areas.

Maximum wind speeds could exceed 80 kilometers per hour off the coast of Hokkaido, and over 70 kilometers on land. In Tohoku, maximum winds of over 60 kilometers are expected.
