INDO-PACIFIC - A rare supertyphoon named "Hinnamnor" has formed over the northern part of the Pacific ocean. This tropical cyclone is currently located east of Okinawa and is presently heading southwest at a speed of around 20 miles per hour.

Winds generated by the cyclone have estimated speed exceeding 150 miles per hour, which make the "Hinnamnor" equivalent of Category 5 hurricane (Saffir-Simpson Scale).

"Hinnamnor" will continue its move southwest until September 2nd, 12:00 UTC. At that moment it will be located 100 miles south of Miyakojima Island, generating winds of around 115 miles per hour around it's eyewall.

Then the cyclone will change its trajectory and will proceed to the north, passing Wengzhou (China) from the east by 200 miles on September 4th, 12:00 UTC, with estimated rating of a Category 3 hurricane (111-130 miles per hour).

Weather warnings were issued for Okinawa and surrounding areas: predicted wind gusts should reach speed up to 69 miles per hour, rainfall should not exceed 6 inches. Kadena Air Force Base (Okinawa) currently remain in Tropical Cyclone Condition of Readiness 4.

It is now unclear how exactly "Hinnamnor" will impact east Asia. However it will likely lengthen drought in China and impact South Korea which experienced flooding earlier this month.
