Security Message for U.S. Citizens: Typhoon Namtheun (Tropical Cyclone 12)

The U.S. Embassy in Tokyo cautions U.S. citizens that Typhoon Namtheun is expected to bring heavy rain and sustained winds to areas of Southern and Western Japan beginning late Saturday, September 3, and continuing through Sunday, September 4. According to current forecasts, the storm will make landfall in Kagoshima Prefecture, Kyushu, at about 9:00 a.m. on September 4 with sustained winds of 75 mph and gusts of up to 90 mph. The storm will then move northward across Nagasaki and Fukuoka Prefectures toward the Sea of Japan.

In conjunction with this storm, the Japan Meteorological Agency has issued high wave, rain and flooding advisories for Kagoshima Prefecture, storm surge and gale advisories for Uki-Yatsushiro and Amakusa regions of Kumamoto Prefecture, and high wave, rain and flooding advisories for areas of Nagasaki 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 and local authorities.

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

Sasebo Naval Base in Nagasaki Prefecture remains at Tropical Cyclone Condition of Readiness (TCCOR) 4, 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.

All U.S. citizens living in or traveling to the area should monitor local weather reports, follow directions from local officials, and take other appropriate actions as needed.
