10 a.m. Thursday, Oct. 15, Guam time: A tropical storm watch has been issued for Saipan, Tinian and Rota by the National Weather Service on Guam. Winds of 39 mph or greater are possible within 48 hours as Tropical Storm Champi approaches to the north, 85 miles north-northeast of Saipan at 4 p.m. Friday.

7:30 p.m. Wednesday, Oct. 14, Guam time: Champi has strengthened into a tropical storm and is on a wobbly west-northwest course that should take it north of the Mariana Islands, then curve northeast toward Iwo Jima at the start of next week, according to the Joint Typhoon Warning Center.
Tropical Depression 25W, # 1
7:30 p.m. Tuesday, Oct. 13, Japan time: Traffic has picked up on Typhoon Alley, with a second new tropical depression forming north of Ujelang in the Marshall Islands. Joint Typhoon Warning Center depicts 25W to track generally northwest, on a path taking it southwest of Iwo Jima by late Saturday as a Category 1-equivalent typhoon. But a vast spread exists among dynamic model guidance, so much could change in the run-up. PST will keep an eye on it. If it becomes a named storm, it will be called Champi, Laotian for red jasmine flower.
Tropical Depression 24W, # 1
6:30 p.m. Tuesday, Oct. 13, Philippines time: As yet unnamed Tropical Depression 24W has spawned west of the Marianas Islands and is forecast by the Joint Typhoon Warning Center to almost due west toward landfall over the northeast coast of the Philippines’ northernmost Luzon Island at mid-afternoon Saturday.
JTWC projects 24W to peak at 144-mph sustained winds and 173-mph gusts as it crashes ashore at about 2 p.m. Saturday some 190 miles north-northeast of the old Clark Air Base. No public storm warning signals have been issued at this time. PST has an eye on it. If it becomes a named storm, it will be called Koppu, Japanese for crater.

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.
