Hurricanes 14E (Madeline), 13E (Lester), # 10

Madeline still on course to knife between Maui, Big Island; may have company in Lester behind it.

Midnight Tuesday, Aug. 30, Hawaii time: The news gets slightly worse for Hawaii as Hurricane Madeline is projected to edge closer to the Big Island to its south and Lester to remain a hurricane even after it passes the 50th State to the north.

According to the Central Pacific Hurricane Center, Madeline, 270 miles east of Hilo and tracking west at 12 mph, is due to pass 67 miles south of Hilo at 6 p.m. Wednesday as a Category 1 hurricane, packing 81-mph sustained winds and 98-mph gusts at center. A hurricane warning remains in effect for the Big Island.

Typhoon 14W, # 2

8 a.m. Wednesday, Aug. 24, Guam time: Tropical Depression 14W isn’t amounting to much right now, save for 30-mph winds and 40-mph gusts over the sparsely populated Northern Mariana islands. It’s forecast by Joint Typhoon Warning Center to move rapidly north the next few days before gradually dying out well east of Japan. All that could change, as some models depict a closer approach to Japan. PST is keeping an eye on it.

Tropical Storm 13W (Kompasu), # 1 FINAL

Noon Saturday, Aug. 20, Japan time: A tropical storm formed overnight east of Japan and it appears as if it will remain off the east coast for its projected very short existence. According to the Joint Typhoon Warning Center, 13W has peaked at 46-mph sustained winds and 58-mph gusts and is forecast to pass 275 miles northeast of Yokosuka Naval Base at about 11 p.m. Saturday before curving northeast and dissipating. Kompasu is Japanese for a V-shaped device for describing circular arcs -- what we would have called a "compass" in old school math classes in the 1960s and 1970s.

Tropical Depression 10W (Mindulle), #22 (Final)

Yet another tropical cyclone has formed that could affect northeastern Japan in a span of a week, following Omais and Chanthu.

6:30 a.m. Tuesday, Aug. 23, Japan time: Mindulle has been downgraded to a tropical depression and is headed rapidly northeast out of Japan and toward its demise. Expect the all-clear to be given at Misawa Air Base at any time. This should be PST’s final update on Mindulle.

Yokota Air  Base still faces some issues restoring power to housing dwellings on the east side after the Biblical flooding that occurred Monday that had many wondering when Noah and the Ark might show up.

Tropical Storm 12W (Lionrock), #45 FINAL: Misawa in TCCOR 1-R

Lionrock arcing toward landfall near Sendai; Misawa remains in TCCOR 2.

Midnight Tuesday, Aug. 30, Japan time: Misawa Air Base has entered Tropical Cyclone Condition of Readiness 1-R (recovery) according to the Misawa Weather Flight official Facebook page. Destructive winds have subsided and Lionrock has rapidly weakened and moved toward the Sea of Japan.

Lionrock is forecast by Joint Typhoon Warning Center to rapidly traverse the Sea of Japan and die out over Manchuria in eastern China. Lionrock became the first cyclone to retain tropical properties since records began being kept to make landfall over Japan’s Tohoku region, striking Iwate Prefecture at 5:50 p.m.

Tropical Depression 11W (Dianmu), # 3 FINAL

2 p.m. Thursday, Aug. 18, Hong Kong time: All wind signals for Hong Kong have been lowered as of 1:15 p.m. This should be PST's final update on 11W.


Noon Thursday, Aug. 18, Hong Kong time: Strong Wind Signal 1 is in effect for Hong Kong as of 11:45 a.m. Signal 3 has been lowered.


11 a.m. Thursday, Aug. 18, Hong Kong time: A stone’s throw just shy of 200 miles southwest of Hong Kong, that messy weather over the last almost whole week has finally morphed into a tropical depression.

Strong Wind Signal 3 was raised overnight Wednesday and was expected to be lowered by mid-day Thursday, according to the Hong Kong Weather Observatory.

11W is forecast by the Joint Typhoon Warning Center to morph into a tropical storm as it passes northwest of Hainan Island before plowing ashore near Haiphong and about 50 miles south of Hanoi in Vietnam late Friday evening. JTWC forecasts 11W to peak at 52-mph sustained and 63-mph gusts as it crashes ashore about 11 p.m. Friday.

Tropical Storm 09W (Chanthu), # 10 FINAL

Tropical Storm 09W (Chanthu), # 5, keeps picking up forward speed, forecast to peak at 75-mph gusts, lower than previous.

8:30 a.m. Wednesday, Aug. 17, Japan time: Tropical Storm Chanthu's forward speed slowed for a bit as it neared the Tokyo-Kanto Plain area overnight Tuesday into Wednesday -- almost as if it wanted to get a nice nighttime view of the world's most exciting city.

But it's now accelerating north-northeast, skimming Japan's east coast, planning to pay a brief visit east of Misawa Air Base on Wednesday afternoon before heading in Hokkaido's general direction and its eventual demise.

Chanthu continues packing 40-mph sustained winds and 52-mph gusts at center. The rain in the Tokyo area has slowed in some spots and stopped altogether in others. Should be cooler the next day or so. PST signs off on Chanthu unless something changes.


6:30 p.m. Tuesday, Aug. 16, Japan time: Fleet Activities Yokosuka entered Tropical Cyclone Condition of Readiness Storm Watch at 2 p.m. Tuesday due to the approach of Tropical Storm Chanthu. U.S. Army Garrison Japan at Camp Zama has a two-hour delay to the start of Wednesday's duty day. Those according to the bases' respective official Facebook pages.

Chanthu remains on course to sideswipe eastern Japan, 80 miles east of Yokosuka at 11 p.m. Tuesday and 26 miles east of Misawa Air Base at 2 p.m. Wednesday, packing sustained 40-mph winds and 52-mph gusts at center.

CFAY's Facebook page stated that Yokosuka and its satellite bases can expect between 2 to 4 inches of rain and wind gusts up to 50 mph. Expect all clear to be announced at Yokosuka by noon Wednesday.


Noon Tuesday, Aug. 16, Japan time: Picking up forward speed. Too far north. Too close to land. Cooler sea-surface temperatures. Dry air engulfing it. All of that spells demise in the next day or so for Tropical Storm Chanthu, moving north-northwest at 16 mph and still on course to graze east Japan early Wednesday morning.

Peak 46-mph sustained winds and 58-mph gusts at center as Chanthu passes 74 miles east of Yokosuka Naval Base at about 2 a.m. Wednesday. diminishing to 40-mph sustained and 52-mph gusts as it passes 33 miles east of Misawa Air Base at around 6 p.m. Wednesday.

All Kanto Plain bases remain in Tropical Cyclone Condition of Readiness All-Clear at the moment. Check with officials channels for possible delays to the start of the nominal work day.


6 p.m. Monday, Aug. 15, Japan time: Tropical Storm Chanthu is again forecast to pass the Tokyo-Kanto area and Misawa Air Base sooner than previously forecast: 100 miles east of Yokosuka Naval Base at 4 a.m. Wednesday and 72 miles east of Misawa at 7 p.m. Wednesday. Joint Typhoon Warning Center has also dialed back peak intensity to 58-mph sustained winds and 75-mph gusts for about 12 hours Tuesday evening into Wednesday morning.


Noon Monday, Aug. 15, Japan time: Little change to Tropical Storm Chanthu's long-range outlook. Slight increase in peak intensity; Chanthu is expected to briefly peak at 63-mph sustained winds and 81-mph gusts at mid-morning Tuesday, then decrease as it pushes north.

Chanthu remains forecast to brush Japan's east coast, about 100 miles east of Yokosuka Naval Base at mid-morning Wednesday, still packing 52-mph sustained winds and 63-mph gusts as it rumbles past; then 52 miles east of Misawa Air Base at 10 p.m. Wednesday, with 46-mph sustained winds and 58-mph gusts at center. Earlier than previously anticipated. And it could be sooner still.


Midnight Sunday, Aug. 14, Japan time: Tropical Storm Chanthu’s forward speed has increased to 18 mph and is now forecast to peak at 58-mph sustained winds and 75-mph gusts at mid-morning Tuesday, lower than previous projections, according to the Joint Typhoon Warning Center.

Chanthu is forecast to pass a wee bit further east of Japan’s east coast as well, and sooner: 106 miles east of Yokosuka Naval Base at 2 p.m. Thursday, instead of mid-evening; then 44 miles east of Misawa Air Base at 10 a.m. Friday, again instead of mid-evening, as previously forecast.

Tropical Storm 08W (Conson), # 9 FINAL

6:30 p.m. Saturday, Aug. 13, Japan time: Conson's demise appears imminent. Joint Typhoon Warning Center reports the tropical storm has picked up forward speed, heading north-northwest at 23 mph, has peaked at 46-mph sustained winds and 58-mph gusts and is about to hit sharply cooler waters and its eventual terminus in the next day or so. This is PST's final update on Conson.


12:15 p.m. Saturday, Aug. 13, Japan time: Tropical Storm Conson's forecast track continues to edge ever so slightly west ... still well away from Japan's east coast, but close enough for Joint Typhoon Warning Center to add a closest point of approach to Narita International Airport.

Conson is tracking north-northwest at 14 mph. JTWC projects Conson's track to bend northwest over the next couple of days, passing some 440 miles east-northeast of Narita at about 10 p.m. Sunday and 300 miles northeast of Misawa Air Base about eight hours later.

Conson is projected to remain a middling tropical storm, peaking at 52-mph sustained winds and 63-mph gusts at center as it rumbles by. Should make for a breezy end ot the weekend and start of the week.


11:30 a.m. Friday, Aug. 12, Japan time: Tropical Storm Conson is forecast to intensify slightly, peaking at 58-mph sustained winds and 75-mph gusts from early morning Saturday into Sunday, according to the Joint Typhoon Warning Center. And though Conson is projected to remain well off Japan's east coast, the forecast track does take it somewhat closer than previous tracks, but still 345 miles northeast of Misawa Air Base early Monday morning. Still much ado about little. PST is watching.


9:45 p.m. Thursday, Aug. 11, Japan time: Tropical Storm Conson's track has shifted northeast, and its Joint Typhoon Warning Center forecast calls for it to peak at even weaker winds than previously projected, 52-mph sustained and 63-mph gusts through much of Saturday.


Noon Thursday, Aug. 11, Japan time: Now, it looks as if Tropical Storm Conson won't intensify into even a Category 1-equivalent typhoon at this point, if the latest from the Joint Typhoon Warning Center is an indicator. It's forecast to peak at 58-mph sustained winds and 75-mph gusts at mid-evening Friday, still more than 2,000 miles east-southeast of Okinawa and no threat to any land mass at the moment. PST will continue to keep watch.


12:30 p.m. Wednesday, Aug. 10, Japan time: Fairly clear, at this point, that Tropical Storm Conson should pass well east of Japan in the coming days, according to the Joint Typhoon Warning Center.

Conson remains more than 2,000 miles east of Okinawa. According to JTWC's  latest update, Conson should peak at 75-mph sustained winds and 92-mph gusts at about 9 p.m. Thursday and remain a Category 1-equivalent typhoon for a day or so.

JTWC projects Conson to pass 620 miles east-northeast of Yokosuka Naval Base at mid-morning Sunday, then continue tracking north toward the Kurile Islands northeast of Hokkaido. Things can change, so PST will keep an eyeball on things.


12:15 p.m. Tuesday, July 9, Japan time: Which way will it go?

That's the puzzling question regarding Conson, which was upgraded overnight to a tropical storm. At 9 a.m., Conson was about 2,200 miles east-southeast of Kadena Air Base, Okinawa, meandering west-southwest at 7 mph.

Joint Typhoon Warning Center's forecast track has Conson bending around to the north for a couple of days later this week, peaking at 75-mph sustained winds and 92-mph gusts at mid-morning Friday.

But the questions loom from there. Dynamic model guidance remains all over the place, considering Conson is but one day old. Some models take Conson into northeastern Japan, others have it curving northeast away from Japan.

It's wait and see at this point.


6:30 p.m. Monday, Aug. 8, Japan time: A new tropical depression has spawned some 400 miles west-southwest of the Wake Island group. Joint Typhoon Warning Center's initial track projects 08W's path to mirror that of Omais, currently tracking east of Japan.

08W is forecast to peak at 75-mph sustained winds and 92-mph gusts at mid-afternoon Thursday, Category 1-equivalent strength. But it should still be well out at sea at that point. And it's way too early to definitively pinpoint its precise path. PST has an eye on it.

If it becomes a named storm, 08W will be called Conson, Vietnamese for an historic place.

Tropical Storm 07W (Omais), # 6 FINAL

6:30 p.m. Monday, Aug. 8, Japan time: Unless Omais does an unexpected curve toward Japan, this should be PST's last installment on a tropical storm that has weakened slightly, down to 52-mph sustained winds and 63-mph gusts at center. Omais has reached its closest forecast point to Yokosuka Naval Base, about 260 miles east at 4 p.m.


7 a.m. Monday, Aug. 8, Japan time: Omais intensified slightly, to 58-mph sustained winds and 75-mph gusts, a fairly strong tropical storm. It remains forecast to stay well off Japan's east coast, 260 miles east of Yokosuka Naval Base by about suppertime Monday. There are a couple of other disturbances out there, one that's drenching Okinawa, the other west of Wake Island; PST has its eye on those as well.


12:45 p.m. Sunday, Aug. 7, Japan time: Omais doesn't appear to be intensifying as projected in earlier updates. It should remain a middling tropical storm through the rest of its forecast existence, and has peaked at 52-mph sustained winds and 63-mph gusts, according to the Joint Typhoon Warning Center. Omais is forecast to pass 284 miles east-southeast of Yokosuka Naval Base at about 10 p.m. Monday. Northerly winds should pick up at Yokosuka overnight Sunday into Monday, diminishing by Tuesday, according to Japan Meteorological Agency forecasts.


6 p.m. Saturday, Aug. 6, Japan time: Omais remains a strong tropical storm and is projected to reach Category 1-equivalent typhoon strength overnight Saturday into Sunday, Joint Typhoon Warning Center reports. Peak winds now forecast to be 86-mph sustained and 104-mph gusts early next week. Omais still forecast to remain well of Japan's east coast, passing about 255 miles east of Yokosuka Naval Base at about 4 a.m. Tuesday.


6 p.m. Friday, Aug. 5, Japan time: Doesn't appear as if Tropical Storm Omais will amount to much more than a Category 1-equivalent typhoon about mid-day Monday, and it should remain well off-shore from the Tokyo and Tohoku regions of Japan

Still, there's a bit of a spread among dynamic model guidance regarding Omais' forecast track in the long term. So, Omais could veer closer to the Tokyo area; it could creep farther east. And keep in mind, Omais is in its relative infancy, just one day of existence.

Omais is forecast to peak at 81-mph sustained winds and 98-mph gusts at mid-afternoon Monday. Joint Typhoon Warning Center's forecast track takes Omais about 275 miles east of Yokosuka Naval Base just past midnight Monday, still packing 75-mph sustained winds and 92-mph gusts, but at its center.

A small-craft advisory remains in effect for Guam and the main Marianas islands until Saturday morning. Gale warnings have been canceled for Saipan and Tinian, though the National Weather Service indicated that both islands will continue to experience 25- to 35-mph winds and 45-mph gusts through Friday evening into Saturday.


12:45 a.m. Friday, Aug. 5, Guam time: A tropical storm has developed 256 miles north of Saipan, tracking north-northwest at 4 mph, but is forecast by the Joint Typhoon Warning Center to pass well east of Tokyo early next week.

Omais, which spawned rapidly into a tropical storm, is forecast by JTWC to peak at 86-mph sustained winds and 104-mph gusts at 10 p.m. Sunday, then rumble 283 miles east of Yokosuka Naval Base, Japan, at about midnight Monday. The Kanto Plain should feel some effects, but the worst should be confined well offshore.

Typhoon 06W (Nida), # 15 FINAL

Hundreds of high-speed trains in southeastern China and flights serving Hong Kong were canceled as Typhoon Nida slammed ashore early Tuesday morning.

5:30 p.m. Tuesday, Aug. 2, Hong Kong time: All tropical cyclone warning signals have been pulled down by the Hong Kong Observatory, as Typhoon Nida continues to make its way inland. This is PST's final update on Typhoon Nida.

10:30 a.m. Tuesday, Aug. 2, Hong Kong time: Typhoon Nida has begun its journey inland still packing sustained 75-mph winds and 92-mph gusts as it roared past the city Tuesday morning, according to the Joint Typhoon Warning Center.

For the moment, Southwest Signal 8 remains raised for Hong Kong; the Hong Kong Observatory reports that should be lowered to Signal 3 sometime after mid-day and before 1 p.m.

The city began Tuesday under virtual lockdown, with 180 flights serving the international airport canceled, the MTR running only limited service, most bus routes suspended and all ferry and tram services canceled, CNN reported. In southeastern China, Shenzen Airport was closed through Tuesday morning, while in Guangzhou, more than 600 high-speed trains were suspended, Xinhua reported via CNN.


7:45 a.m. Tuesday, Aug. 2, Hong Kong time: Hundreds of high-speed trains in southeastern China and flights serving Hong Kong were canceled as Typhoon Nida slammed ashore early Tuesday morning.

Nida was packing sustained 92-mph winds and 115-mph gusts as it made landfall at about 5 a.m. Tuesday. It’s forecast by the Joint Typhoon Warning Center to maintain strong tropical storm-force winds, 63-mph sustained and 81-mph gusts as it makes its way inland.
