Okinawa bases to enter TCCOR All Clear on Dec. 1

2 p.m. Friday, Nov. 29, Japan time: Tropical Cyclone Condition of Readiness All Clear is due to be issued at 1 minute past midnight Sunday, Dec. 1 by Kadena Air Base’s 18th Wing commanding officer Brig. Gen. Joel Carey, signaling the end of the northwest Pacific’s tropical cyclone season.

U.S. bases on Okinawa remain in seasonal TCCOR 4 from June 1 to Nov. 30 because of the island’s location, which is close to portions of the northwest Pacific where tropical cyclones are apt to form, sometimes with little warning.

TCCOR 4 signals that destructive winds of 58 mph or greater are possible within 72 hours. Between Dec. 1 and May 31, tropical cyclone development is historically less likely for Okinawa and bases in Korea and Japan’s main islands; thus, TCCOR All Clear is declared on Dec. 1 each year.

U.S. bases on Guam remain in TCCOR 4 year-round due to its location in the heart of the tropics. In fact, some of the most destructive storms to hit the island have done so outside of the typical tropical cyclone season months.

Those included Pongsona (December 2002), Paka (December 1997), Pamela (May 1976) and Typhoon Karen, which leveled Guam in November 1962 and occurred near the end of the typhoon season.
