As Krovanh was approaching the Philippines, Taiwan's Central Weather Bureau cautioned the residents of the island against strong winds and warning ships in the Bashi Channel. After the typhoon entered the South China Sea, sea warnings were issued for areas offshore Hainan. Additional warnings were issued and expanded as Krovanh moved closer to the Chinese coast. In preparation for the storm, shipping routes across the Qiongzhou Strait were suspended, while security measures for river dykes and reservoirs were strengthened in both Hainan and Guangdong. In Hong Kong, the Hong Kong Observatory issued a Standby Signal No. 1 on August 23, which was upgraded to a Strong Wind Signal No. 3 at around noon the following day. All warning signals in Hong Kong were discontinued on August 25. In Guangzhou, 15 flights were cancelled in anticipation of Krovanh, stranding 500 passengers.
