U.S. bases on Okinawa to revert to TCCOR All Clear

3 p.m. Sunday, Nov. 29, Japan time: At midnight Monday, U.S. bases on Okinawa enter Tropical Cyclone Condition of Readiness All Clear, signaling the end of the 2015 northwest Pacific typhoon season. The season typically runs from June 1 to Nov. 30, as it does in the north Atlantic.

The declaration of TCCOR All Clear is made by the commanding officer of Kadena Air Base’s 18th Wing; he speaks in one voice for all bases on Okinawa regarding tropical cyclones. Seasonal TCCOR 4 resumes at 1 minute past midnight on June 1.

Typhoon 27W (In-fa), #16 FINAL

In-fa continues to intensify as it has begun curving northwest, and as the Joint Typhoon Warning Center reports that model guidance is in better agreement on a track that takes In-fa just south of Guam as the weekend begins.

4 p.m. Saturday, Nov. 21, Guam time: Typhoon In-fa is moving west away from the main Marianas islands, Guam has resumed seasonal Condition of Readiness 4, but high surf and strong winds remain in the area. High-surf and small-craft advisories remain in effect. Unless something major changes, this is PST's last update on In-fa.

7:30 a.m. Saturday, Nov. 21, Guam time: Typhoon In-fa is making its closest point of approach to Guam, passing some 170 miles south-southwest of the island, keeping much of its fury well out of harm’s way. The island should experience 40-mph gusts plus showers, some heavy at times, as In-fa passes.

Shelters remain open at five school locations. Guam International Airport remains open with no flights canceled at the moment. Guam remains in Condition of Readiness 2; unless something changes, seasonal COR 4 will likely resume later Saturday.

Typhoon 25W (Champi), # 8

Typhoon Champi

8:30 a.m. Monday, Oct. 19, Japan time: Champi has been downgraded after a brief life as a super typhoon, according to the Joint Typhoon Warning Center. Champi remains far from any significant land mass, 555 miles north-northwest of Guam and packing sustained 145-mph winds as it crawls north-northeast at 3 mph, according to the National Weather Service on Guam. Typhoon-force winds extend 40 miles from center and tropical storm-force winds 185 miles.

1 a.m. Monday, Oct. 19, Guam time: Champi has been upgraded to super-typhoon status by the Joint Typhoon Warning Center, but is still far from any significant land masses and looks to stay that way.

Tropical Storm 24W (Koppu), #19

Typhoon Koppu is seen just east of Luzon island in the Philippines in this NOAA satellite image taken Saturday morning, Oct. 17, 2015, Philippines time.

7 a.m. Wednesday, Oct. 21, Philippines time: Koppu continues to fall apart; it could become a tropical depression by this afternoon and dissipate altogether in the next day or so. Winds have diminished to 40-mph sustained and 52-mph gusts at center. Public Storm Warning Signal 1 remains in effect for northern Luzon and the groups of islands to the north. Unless it regenerates, which is unlikely, this will be PST’s last post regarding Koppu.

Midnight Tuesday, Oct. 20, Japan time: Koppu continues to linger just north of Luzon, still a fairly strong tropical storm, packing sustained 52-mph winds and 63-mph gusts at center, but is rapidly deteriorating and could die out well before reaching Okinawa’s vicinity, perhaps sooner, according to the Joint Typhoon Warning Center.

Second tropical disturbance sighted; advisories still in effect for Guam

8:45 a.m. Tuesday, Oct. 13, Guam time:Small-craft and high-surf advisories remain in effect for Guam, Tinian, Rota and Saipan as a tropical disturbance continues its march through the Marianas Islands.  Winds gusting to 45 mph and four inches of rain or more remain in the cards. Worse, a second tropical disturbance has formed northeast of Pohn’pei. Looks like traffic is picking up along Typhoon Alley. PST will keep its eye on each.

6:30 p.m. Monday, Oct. 12, Guam time: A tropical cyclone formation alert has been issued on a new tropical disturbance east of Guam. The initial bulletin from the Joint Typhoon Warning Center indicates Area 91W is forecast to knife its way between Rota and Saipan through Tuesday afternoon, causing winds between 25 and 35 mph with gusts up to 45 mph, rainfall between 3 to 6 inches and possible flooding in low-lying areas. A flash-flood watch has been issued for Guam, Rota, Tinian and Saipan through Tuesday afternoon.

Typhoon 21W (Dujuan), # 17 FINAL

Typhoon Dujuan

11:20 a.m. Monday, Sept. 28, Japan time: U.S. bases on Okinawa have reverted back to seasonal Tropical Cyclone Condition of Readiness 4, as Dujuan continues hurtling west-northwest toward primary and secondary landfalls over Taiwan and southeastern China later Monday into Tuesday.

Dujuan passed 281 miles southwest of Kadena Air Base at 8 p.m. Sunday. Strongest winds were 23-mph sustained and 37-mph gusts at Kadena and 29-mph sustained and 41-mph gusts at 4:15 p.m. Sunday. Depending on where one was standing on Okinawa, they got anywhere from trace amounts to 3 inches of rain. This is the last update on Typhoon Dujuan.

Tropical Storm 18W (Etau), # 2 FINAL

6:30 a.m. Friday, Sept. 11, Japan time: Tropical Storm Etau didn’t affect U.S. military facilities in Japan, didn’t become a typhoon in the classic sense, but the amount of rainfall associated with Etau was simply epochal. More than 2 feet of rain fell in Tochigi and Ibaraki Prefectures in a 24-hour period, causing widespread flooding and evacuation of some 300,000 people due to flooding and landslides, according to American and Japanese media reports; looked quite like the tsunami associated with the March 11 earthquake 4½ years ago. Etau has dissipated, but the cleanup could take weeks.

10 a.m. Monday, Sept. 7, Japan time: A new tropical depression spawned overnight Sunday southwest of Iwo Jima, but it doesn’t appear as if unnamed 18W may become a significant typhoon. It’s forecast to track rapidly north and dissipate over southwestern Honshu, close to Marine Corps Air Station Iwakuni but as a minor tropical depression. 18W is projected to peak at 69-mph sustained winds early Wednesday morning before rapidly eroding before it hits east Shikoku. PST will keep an eye on it in case it develops further.

Typhoon 03C (Kilo), #2

10 a.m. Monday, Sept. 7, Japan time: Doesn’t appear at this point as if Typhoon Kilo will be a threat to land. Entering its 18th day of existence, Kilo is due to move west, then curve north and northeast well of the east coast of Japan’s central island of Honshu by the weekend. Unless the track deviates significantly closer to land, this should be the last update on Kilo.

1 a.m. Wednesday, Sept. 2, Wake time: Kilo, which began as a tropical depression and morphed into the central Pacific’s third tropical cyclone of the season, is set to become the second such storm to cross the International Dateline and become a northwest Pacific typhoon, much as Halola did in July.

Hurricane 12E (Ignacio), # 3

Ignacio one of three tropical cyclones roiling in the eastern Pacific; Hawaii could feel effects in next few days.

2:30 a.m. Monday, Aug. 31, Hawaii time: With every passing update, it looks more and more as if Hurricane Ignacio may threaten Hawaii less and less. The National Weather Service has discontinued a tropical storm watch, stating tropical storm-force winds were no longer expected to reach the islands.

Ignacio continues diminishing as it heads northwest, and is now due to pass 260 miles northeast of Hilo on the Big Island at about 10 p.m. Monday, and 260 miles northeast of Camp H.M. Smith on Oahu and 300 miles northeast of Barking Sands on Kauai between 9 p.m. Tuesday and 8 a.m. Wednesday as a Category 1 hurricane.

Typhoon 17W (Atsani), # 13 FINAL

5:30 p.m. Sunday, Aug. 23, Japan time: Typhoon Atsani has a few more days of life left in it, but it most likely won’t threaten any land masses if it remains on its current Joint Typhoon Warning Center forecast track. Atsani has curved northeast, it remains well away from any land masses and is forecast to die out late in the week over the north Pacific Ocean. Unless something changes, this is the last update on Typhoon Atsani.

7:15 a.m. Friday, Aug. 21, Japan time: Atsani has been downgraded to a Category 3-equivalent typhoon and remains forecast to curve northeast, well out of range of the Tokyo-Kanto Plain area, according to the Joint Typhoon Warning Center.
