Travel Alert August 2018: Typhoon Shanshan to Affect Tokyo and Northern Japan

If Tokyo and other areas of northern Japan are in your travel plans over the next few days, you may want to consider delaying your travel — or, at least, keep yourself updated as to the latest information pertaining to the weather — due to Typhoon Shanshan, of which landfall is possible in eastern Japan east of Tokyo as early as Thursday afternoon, August 9, 2018.

Typhoon Shanshan

Maximum sustained winds of this storm — which is currently centered approximately 560 miles southeast of Tokyo and is moving north northwest at approximately 12 miles per hour — are 80 miles per hour, with gusts of up to 115 miles per hour; and it has passed well east of the island of Iwo Jima. Having attained typhoon status only within the past few hours, this system could possibly strengthen to a Category 2 typhoon before possibly weakening back to a Category 1 typhoon prior to arriving at or near east-central Honshu on the eastern coast of central Japan.

The greater Tokyo metropolitan area could receive as much as four inches of rain and peak wind gusts as high as 115 miles per hour; but local areas can experience additional rainfall, which will result in significant flooding. A dangerous storm surge is also likely to occur along the coast — along with mudslides, damaging winds, rough seas and surf.

To compound matters, the recent arrival of Typhoon Jongdari brought heavy rainfall and damaging winds to some of the aforementioned areas. Widespread power outages and tree damage — as well as an elevated risk for mudslides and transportation disruptions — could be the results of another round of heavy rainfall and strong winds due to the potential impact of Typhoon Shanshan.

Flight Waivers, Delays and Cancellations

If you are traveling to Tokyo and northern Japan over the next few days, expect delays and cancellations of flights. Keep up to date on the latest information pertaining to this tropical weather system which may adversely affect your travel plans. Better yet, postponing or canceling your trip might be a better option — no matter which mode of travel you plan on taking.

If you have a flight scheduled, your flight may be delayed or canceled — and you may be eligible for a waiver of a fee to change your itinerary. If you are driving in any of these areas, watch out for deteriorating weather conditions and traffic problems.

Here are six airlines which have issued travel alerts — or are at least monitoring the storm — as a result of this tropical weather system:
