Security Message for U.S. Citizens: Tropical Cyclone Lionrock

The U.S. Embassy in Tokyo cautions U.S. citizens in the Tokyo region that Typhoon LIONROCK (Tropical Cyclone 10) is expected to bring heavy rain and sustained winds up to 30 mph, with 60-mph gusts, to the region beginning in the evening of Monday, August 29 and continuing throughout Tuesday, August 30.

Storm tides, heavy rainfall, damaging winds, and flooding may occur, and transportation may be disrupted. If you are traveling, please confirm your schedule with your airline or train line as the storm may cause unexpected delays.

In conjunction with this storm, the Japan Meteorological Agency has issued high wave warnings and gale advisories for Shizuoka prefecture and the Izu and Ogasawara islands, and high wave and gale advisories for Chiba, Ibaraki, Fukushima, Miyagi and Iwate prefectures. The Japan Meteorological Agency has also issued a heavy rain and landslide warning for Nagano prefecture. U.S. citizens in those areas of Japan should exercise particular caution. The Embassy recommends monitoring all advisories and warnings issued by the Japan Meteorological Agency.

According to current projections, Lionrock will make landfall in Miyagi prefecture near Sendai at approximately 3:00 p.m. JST on August 30, and continue in a northwesterly direction. Lionrock is forecast to remain a Category 1 typhoon as it makes landfall, with 81-mph sustained winds and 98-mph gusts.

Misawa Air Base in Aomori prefecture and Yokosuka Naval Base in Kanagawa prefecture remain at Tropical Cyclone Condition of Readiness (TCCOR) 3, meaning destructive winds are possible within 48 hours.

The Japan Meteorological Service’s Typhoon tracking information may be found in English at this webpage. Information about Tropical Storm Mindulle is also available from the Joint Typhoon Warning Center.

Note that the current Tropical Cyclone Condition of Readiness (TCCOR) for U.S. military installations on Okinawa may be found online here.
