Typhoon making atmospheric conditions unstable over much of Japan

Typhoon Hinnamnor is expected to re-approach Japan's southern prefecture of Okinawa after briefly moving away to the south.

Japan's Meteorological Agency says as of Thursday morning the violent typhoon was moving southwest at a speed of 25 kilometers per hour over waters 250 kilometers south of Miyakojima Island.

The maximum wind velocity near its core was 198 kilometers per hour, with gusts of 270 kilometers per hour.

The storm is expected to gain force as it moves south of Okinawa, where it will likely remain stationary through Friday.

Winds are picking up in the Okinawa region and the seas are turning rough.

Maximum winds of 72 kilometers per hour are expected in the region through Friday, with gusts of 108 kilometers per hour.

The typhoon will then move back up north and come very close to the Sakishima Islands and Okinawa's main island from Saturday through Sunday.

The Sakishima Islands can expect maximum winds of 144 to 180 kilometers per hour, and gusts of 198 to 252 kilometers per hour, through Saturday. The region will see 10-meter-high waves on Saturday.

People are urged to remain on alert for gale-force winds and high waves, and to stay updated on evacuation notices and other information regarding the typhoon.
The storm will then likely move north through the East China Sea, and could impact some parts in western Japan.

Meanwhile, a front and moist air are making atmospheric conditions unstable in many regions of western and eastern Japan, and spawning localized rainclouds.

Himeji City in Hyogo Prefecture had 67 millimeters of rain in the hour through 11 a.m. Thursday.

Officials in Ishikawa Prefecture have issued landslide warnings for some areas.

Atmospheric conditions will remain unstable, bringing thunderstorms and localized downpours.

Chugoku, Kinki and Tokai regions are expected to have 100 millimeters of rain over a 24-hour period through noon on Friday. Hokuriku and Tohoku will have 80 millimeters.

The Tokai region could have another 100 to 150 millimeters of rain in the 24-hour period through noon on Saturday.

The Meteorological Agency is calling on people to be on alert for landslides, flooding in low-lying areas, swollen rivers, lightning strikes and tornados.
