1:30 p.m. Wednesday, Oct. 5, Japan time: Fleet Activities Sasebo at 1:30 p.m. issued the all clear regarding Typhoon Chaba.

Noon Wednesday, Oct. 5, Japan time: Fleet Activities Sasebo has entered Tropical Cyclone Condition of Readiness 1-R (recovery). Destructive winds no longer occurring. Repair crews and staff civil are fanning out to assess damage and establish safe zones. Please stay indoors until all clear is annouced by CFAS.

11:30 a.m. Wednesday, Oct. 5, Japan time: Chaba continues hanging onto typhoon status, raking Korea's southeast coast and Japan's southwestern Kyushu island with heavy gusts and sideways rain.

But it continues to deteriorate and is picking up forward speed headlong northeast away from Korea's southeast coast and Kyushu, according to the Joint Typhoon Warning Center.

At 9 a.m., Chaba was 115 miles northwest of Sasebo Naval Base, heading northeast at 23 mph, still packing 86-mph sustained winds and 104-mph gusts at center. Closest point of approach to Sasebo 104 miles and to Pusan is 35 miles at about mid-day Wednesday.

Fleet Activities Sasebo remains in Tropical Cyclone Condition of Readiness 1-C (caution) and Area IV in Korea in TCCOR 1.

JTWC reported sustained 52-mph winds and 63-mph gusts in Pusan as Chaba passed.

Chaba remains on track to pass 107 miles north-northwest of Marine Corps Air Station Iwakuni at about 2 p.m. as a severe tropical storm. MCAS Iwakuni remains in TCCOR Storm Watch.

6:30 a.m. Wednesday, Oct. 5, Japan time: Chaba’s life as a typhoon is quickly dwindling as it continues pushing northeast into cooler conditions. It continues on course through the Tsushima Strait between Korea’s southeast coast and the northwestern edges of Kyushu, according to the Joint Typhoon Warning Center.

If it remains on its current path, Chaba is forecast to split the difference between Sasebo Naval Base and Chinhae Naval Base, passing 76 miles northwest of Sasebo and 72 miles southeast of Chinhae between 8 and 9 a.m. Wednesday, packing 98-mph sustained winds and 121-mph gusts at center.

Fleet Activities Sasebo set Tropical Cyclone Condition of Readiness 1-Caution, with 40-mph sustained winds occurring on station. Area IV bases in Korea remain in TCCOR 1.

Chaba remains forecast to pass 102 miles north-northwest of Marine Corps Air Station Iwakuni as a severe tropical storm about mid-day Wednesday. Iwakuni remains in TCCOR Storm Watch.

10:30 p.m. Tuesday, Oct. 4, Japan time: Prepare for Tropical Cyclone Condition of Readiness 1-C (caution) and destructive winds to begin at about midnight, according to Fleet Activities Sasebo’s official Facebook page. Area IV in Korea remains in TCCOR 1. Typhoon Chaba continues to bear down on the Tsushima channel between Pusan and Sasebo. Gonna be a gusty, sideways-rainy overnight.

6:08 p.m. Tuesday, Oct. 4, Japan-Korea time: Tropical Cyclone Condition of Readiness 1 has been set at 6 p.m. at Sasebo Naval Base, joining U.S. bases in Korea's Area IV across the Tsushima channel.

At 3 p.m., Typhoon Chaba was 235 miles north-northwest of Kadena Air Base, Okinawa, and is tracking due north at 18 mph, packing 138-mph sustained winds and 167-mph gusts at center.

If Chaba remains on current course, it's forecast to pass closer to Korea's southeastern edges and a bit further away from Sasebo, but close enough to cause some major discomfort overnight Tuesday into Wednesday.

Chaba is forecast to rumble 113 miles north-northwest of Sasebo at 10 a.m. Wednesday, and still packing a might wallop: 115-mph sustained winds and 144-mph gusts at center as it roars past.

That means worse news for Pusan and Chinhae Naval Base. Chaba is due to pass just 23 miles south of Korea's second-largest city, along its southeast coast, and 36 miles south-southeast of Chinhae Naval Base just to Pusan's west between 11 a.m. and noon Wednesday.

Marine Corps Air Station Iwakuni remains in TCCOR Storm Watch and is a bit further south of Chaba's forecast track: 121 miles north-northwest of Iwakuni about three hours after passing Pusan, and still packing 92-mph sustained winds and 115-mph gusts at center. Still pretty nasty.

1:45 p.m. Tuesday, Oct. 4, Korea time: U.S. bases in Daegu Area IV have been placed in Tropical Cyclone Condition of Readiness 1.

Destructive winds of 58 mph or greater are anticipated within 12 hours.

Winds up to 46 mph sustained with 69-mph gusts are forecast for between midnight Tuesday and 3 p.m. Wednesday. Between 3 and 6 inches of rain also possible between 9 p.m. Tuesday and 3 p.m. Wednesday.

11 a.m. Tuesday, Oct. 4, Japan-Korea time: Chaba has been downgraded from a Category 5-equivalent super typhoon to Category 4-equivalent status. Still a vicious beast, and still bound for the Tsushima Strait between Japan and Korea's southeast coast, according to the Joint Typhoon Warning Center.

At 9 a.m., Chaba was 415 miles south-southwest of Sasebo Naval Base, chugging north at 13 mph, still packing 144-mph sustained winds and 173-mph gusts at center.

As Chaba moves north, it's forecast to start diminishing as it approaches the Tsushima channel, down to Category 2-equivalent status.

Chaba is forecast by JTWC to split the difference between Kyushu and the southeastern edges of Korea.

If it remains on its forecast track, Chaba is due to pass 76 miles north-northwest of Sasebo Naval Base and 74 miles south-southeast of Chinhae Naval Base between 9 and 10 a.m. Wednesday. It'll be packing 98-mph sustained winds and 121-mph gusts at center.

Fleet Activities Sasebo and Korea's Area IV remain in Tropical Cyclone Condition of Readiness 2. Area IV can expect 46-mph sustained winds and 69-mph gusts with 3 to 5 inches of rain, according to U.S. Army Garrison Daegu's official Facebook page.

Chaba's pace should then pick up rapidly, passing 90 miles north-northwest of Marine Corps Air Station Iwakuni, barely hanging on to typhoon status at that point. MCAS Iwakuni remains in TCCOR Storm Watch.

10 a.m. Tuesday, Oct. 4, Korea time: U.S. bases in Korea's Area IV, the Daegu-Pusan corridor, have been placed in Tropical Cyclone Condition of Readiness 2. Destructive winds of 58 mph or greater are anticipated within 24 hours. Between 3 to 5 inches of rain forecast for eastern Korea.

9:30 a.m. Tuesday, Oct. 4, Japan time: U.S. bases on Okinawa have reverted to seasonal Tropical Cyclone Condition of Readiness 4.

6 a.m. Tuesday, Oct. 4, Japan time: U.S. bases on Okinawa have entered Tropical Cyclone Condition of Readiness 1-R (recovery). Destrucive winds of 58 mph or greater are no longer occurring.

That doesn't mean it's safe to leave the house and resume life as normal. Now it's time for staff civil, survey teams and repair crews to begin fanning out to assess damage.

Though the winds weren't as bad as predicted, there still could be quite a bit of damage out there: Downed power lines, tree limbs, flooding, unstable structures; all this and more could be the result of Super Typhoon Chaba as it gave Okinawa a glancing blow last night.

And there's no set period when TCCOR 1-R begins and ends. No fixed time. It depends on how much damage there is and how much time it will take to clear it.

So, stay indoors. Wait for the 18th Wing command to issue the all-clear/resume seasonal TCCOR 4.

DODEA-Okinawa schools will remain closed on Tuesday and all after-school activity has been canceled as well. School will resume normal schedule on Wednesday, according to DODEA-Pacific officials.

Peak winds on Okinawa were 44-mph sustained and 75-mph gusts at midnight. Some 4,000 homes across the prefecture lost power and more than 300 flights serving Naha International Airport were canceled.

5:40 a.m. Tuesday, Oct. 4, Korea time: Korea is by no means immune to Super Typhoon Chaba's ferocity. U.S. Army Garrison Daegu/Area IV has set Tropical Cyclone Condition of Readiness 2.

TCCOR 2 by definition means: Destructive winds of 58 mph or greater are anticipated withn 24 hours.

Southeastern coastal areas of Korea are closest to the line of fire. Joint Typhoon Warning Center forecast calls for Chaba to pass 51 miles south-southeast of Pusan and 68 miles south-southeast of Chinhae Naval Base between 8 and 9 a.m. Wednesday.

USAG Daegu's official Facebook page states that winds exceeding 58 mph are anticipated in Area IV between midnight Tuesday and 3 p.m. Wednesday, peaking at 46-mph sustained and 69-mph gusts. Between 3 to 5 inches of rain are forecast for eastern Korea.

5 a.m. Tuesday, Oct. 4, Japan time: Fleet Activities Sasebo and its properties are in Tropical Cyclone Condition of Readiness 2. Destructive winds of 58 mph or greater anticipated within 24 hours.

If Super Typhoon Chaba remains on its current path, it's forecast to pass 81 miles northwest of Sasebo at 7 a.m. Wednesday, still packing a pretty good punch, 104-mph sustained winds and 127-mph gusts at center.

Also, Marine Corps Air Station Iwakuni is in TCCOR Storm Watch. Chaba is forecast to pass 92 miles north-northwest of Iwakuni at 1 p.m. Wednesday, remaining a Category 1-equivalent typhoon, 75-mph sustained winds and 92-mph gusts at center. Iwakuni can expect 56-mph winds and 73-mph gusts by that time.

10:30 p.m. Monday, Oct. 3, Japan time: U.S. bases on Okinawa have been placed in Tropical Cyclone Condition of Readiness 1-E. Destructive winds of 58 mph or greater are actually occurring. All outdoor activity is prohibited.

7:30 p.m. Monday, Oct. 3, Japan time: Talk about a super typhoon oddity. While Chaba has intensified drastically in the past day or so, the peak forecast winds for Okinawa have been dialed down just as dramatically.

Here's the latest wind-forecast timeline from Kadena Air Base's 18th Wing Weather Flight. U.S. bases on island remain in Tropical Cyclone Condition of Readiness 1-C; expect upgraded to 1-E within a couple of hours.

-- 40-mph sustained winds or greater: Occurring now.
-- 58-mph sustained winds or greater: 9 p.m. Monday.
-- Peak 81-mph sustained winds, 104-mph gusts at center: 9 p.m. Monday.
-- Winds diminishing below 58-mph sustained: 3 a.m. Tuesday.
-- Winds diminishing below 40-mph sustained: 8 a.m. Monday.
