With the 04Z update from the Japan Meteorological Agency, Typhoon Fitow is located 195 km south-southwest of Okinawa or 165 km east of Miyako-jima and continues to move toward the northwest at 9 kt. Current winds from JMA is 70G100 kt while the Joint Typhoon Warning Agency is reporting 90G110 kt. (Note that JMA’s speeds are reported with a 10-minute average versus JTWC’s 1-minute average, which usually yields about a 14% difference.)
All agencies warning on Fitow are in generally agreement: storm-force winds and heavy rains will batter Okinawa and Miyako-jima today before affecting northern Taiwan Sunday afternoon and evening. Landfall in Fujian province, China, should occur early Monday morning as the storm weakens thanks to a strong jet stream that is enhancing upper-level shear.
The latest reports from Kadena Air Base social media sites is that the base is in Tropical Cyclone Condition of Readiness 1-Caution (TCCOR 1-C), which mean destructive winds of 50 kt or greater are anticipated within 12 hours while the actual winds are 34-49 kt. The terminal forecast from Kadena has 50 kt sustained winds between 2 PM and 6 PM JST. As of now, sustained winds in the low- to mid-30s with gusts in the lower 50s (kt) have been reported.
