2010-08-13 20:15 JST

Typhoon DIANMU made landfall near Akita City at 17 JST yesterday, passed over Akita and Iwate Prefecture to reach the Pacific Ocean, and became an extra-tropical cyclone. Heavy rains and strong winds were reported from many places in Japan, but it seems large-scale disasters did not occur by this typhoon.

Typhoon DIANMU skirted Jeju Island and made landfall at Goheung Peninsula in Jeollanam-do Province yesterday, and five people killed in Korea due to heavy rains. Then the typhoon moved off the coast of Oki Islands and now is located off the coast of Noto Peninsula in Japan Sea. Clouds extending to south from the typhoon are causing heavy rains in Western Japan (radar image)), and moreover, record-breaking heavy rains have been observed in the south of Hokkaido due to the front. The amount of rain in this area will increase more because this area will be affected by the clouds of typhoon from now.

Typhoon DIANMU is approaching to Jeju Island, Korea. This typhoon has intensified a little while moving northward over East China Sea, and started to have the 50-kt storm wind circle since this morning, which is covering Jeju Island now. Goto Islands in Nagasaki Prefecture are also within the gale wind circle, and maximum wind speed is increasing in that area. It is forecast to pass near Tsushima Island and enter into Japan Sea, and Northern Kyushu and Chugoku Area may be within the storm wind circle tomorrow.

Typhoon DIANMU has passed just east of Miyakojima Island, and now moving to west of Jemima Island. The maximum wind speed is not so much intense, but the gale wind circle seems to be large, and Okinawa Island is already within the gale wind circle (track information on Google Maps). Strong winds (plus storm surges and storm tides) may be observed in wide areas. Watching the radar image, the clouds of the typhoon is biased to the south-east quadrant, which means that heavy rains are more likely occurred after the typhoon passed the area.

Typhoon DIANMU was formed in south of Miyakojima Island. We have seen the clusters of clouds in south of Okinawa for a few days, but the center of them has been unclear. Yesterday the center is getting clear in south of Miyakojima Island, and it became a typhoon in the night. It seems, however, that a typhoon with clouds biased in the south is difficult to intensify judged from similar cases in the past, so how is this time? In any case, we need to be careful for storm tides and heavy rains in Okinawa. Checking the track information on Google Maps, Miyakojima Island is already inside the 30kt gale wind circle.
