FORECAST

Weather models are still expecting large amounts of rain to be dumped by In-fa on the Okinawa Islands, Taiwan, and China with some local areas expected to receive as much as 750 mm of rain (~30 inches.) Winds remain a major threat with gale winds extending for hundreds of kilometers away from the eye.

Latest Force Thirteen forecast cone expect In-fa to regain Major Hurricane-equivalent Typhoon with the second peak reaching 10-minute winds of 180 kph (1-minute winds of 120 mph) as it moves northwest for the next 60 hours. Then it’s expected to move northeast towards South Korea and Japan, still as a typhoon. The forecast cone remained highly uncertain due to the uncertainty on the Subtropical Ridge that’s determining the storm’s movement.

Force Thirteen advises people in East Asia to remain vigilant on the storm’s movement and do measures to mitigate any damage.
