Areas along the Pacific coast should brace for torrential rain Monday due to an unstable atmosphere affected by a weather front, a cold air mass from the north and Typhoon No. 14, which is moving east over the ocean south of Japan, the Meteorological Agency warned Monday morning.

Precipitation may exceed 30 mm per hour in some areas, NHK reported, without naming specific areas that may be affected. The agency is warning that heavy rain may cause landslides and bring floods to lowlands, as well as calling for caution against stormy conditions, including high waves, at sea, it said.

The agency said the typhoon was moving east-northeast at 25 kph over the sea area about 400 km southeast of Tanegashima Island, Kagoshima Prefecture, as of 3 a.m. Monday, with a central atmospheric pressure of 985 hectopascals and packing a maximum wind velocity of 90 kph and maximum instantaneous wind velocity of 126 kph near its center, according to NHK.

The typhoon is expected to continue to grow as it moves northward in sea areas south of Japan, bringing increasingly strong winds to the Izu and Ogasawara island chains during Monday.

The expected maximum wind velocity may reach 65 kph in the Izu island chain and 54 kph in the Daitojima area in Okinawa Prefecture and the Ogasawara island chain.

The Izu island chain may come under strong winds and face very stormy seas Tuesday, affected by the typhoon, according to NHK.
