Typhoon MUIFA is located in south of Okinawa Main Island, and is turning slowly to northwest. Weather radar data shows that heavy rains and strong winds are now being observed in Okinawa Main Islands. Data at Miyagijima (Uruma City, Okinawa) shows that the wind got stronger to the midnight, then got weaker before dawn, and again got stronger in the morning. This typhoon has a large eye structure, which seems to be the double (concentric) eye, so this structure might have appeared in the observation data. This typhoon is moving slowly, so it will affect this region for a long period of time.

Typhoon MUIFA is moving on a complex track, but is now moving toward west, and Daitojima area entered into the gale-wind circle. In the near future, Sakishima Islands will be affected more by the typhoon.

Typhoon MUIFA was formed in east of Philippines. The previous typhoon, Typhoon NOCK-TEN, moved toward Philippines, but this typhoon is forecast not to go so far as that, and is expected to turn north earlier. The typhoon can move north because the subtropical high pressure system is not powerful at the moment, and this in turn brings relatively cooler summer to Japan.

Typhoon MUIFA showed rapid intensification of 60hPa deepening in 24 hours. We can also see the eye of the typhoon. This typhoon is moving north slowly, so the turbulence of the sea will continue for a long period around Okinawa, where the typhoon is heading.
