As Omais approached South Korea, the Korea Meteorological Administration warned of heavy rainfall and high winds across Jeju and the southern coast of mainland South Korea.[2] Numerous fishing vessels evacuated to the port in Yeosu.[3] A total of 27,413 vessels were guided to harbor in Jeollanam-do. Due to concerns of mudslides, more than 12,000 people were ordered to evacuate across Jeollanam-do. About 350 authorities were stationed in areas prone to mudslides while 405 civil servants were tasked with disaster coordination.[4][5] In Busan, numerous landslide warnings were issued. A total of 33 people were evacuated from an apartment building in a flood-prone part of the city. Airlines collectively cancelled 75 flights to Jeju, ten flights at Gimhae International Airport, three flights at Gwangju Airport, and two flights at Ulsan Airport. A total of 15 passenger ships were docked due to the storm. Across 17 national parks, 422 tours were cancelled.[5] At Jirisan National Park, mountain climbing was temporarily banned on August 23, with planned inspections of damage following the storm.[6]
Elsewhere
editIn anticipation of a landfall on Guam, the National Weather Service (NWS) issued a tropical storm watch at 22:36 UTC on August 14.[7][8] At 10:00 UTC on August 15, the NWS issued a tropical storm watch for the island of Rota.[9] However, all watches were lifted by the NWS at 09:14 UTC the next day as the system weakened.[10] A flash flood watch was also issued for Rota, Tinian, and Saipan due to the threat of up to 4 in (102 mm) of rainfall.[11] The United States Navy raised the Tropical Cyclone Condition of Readiness to Level 3 for Joint Region Marianas early on August 15.[12] Military bases on Guam began to secure faculties and warn residents of military housing of the impending storm. Although public schools and government offices remained open on August 16, several public schools held early releases on August 16 and closed the following day. The Guam Department of Public Works prepared heavy equipment to clear drainage systems of debris.[8] As the storm impacted Guam, an urban and small stream flood advisory was issued.[13] More than 3 in (76 mm) of rain fell across Guam.[14]
In advance of Omais, the United States Navy raised the Tropical Cyclone Condition of Readiness to Level 4 at Kadena Air Base.[12] Heavy rainfall and strong winds were reported in Miyakojima.[15]
