The Taiwanese Central Weather Bureau issued warnings for ships in the vicinity of Taiwan's northern and eastern shores on August 28 as Prapiroon approached the island. Forecasts anticipated the tropical cyclone to track northeast of the island. Schools in Yilan and Keelung were temporarily closed on August 29 due to the storm. In Chongming Island near Shanghai, evacuation procedures were initiated, resulting in the displacement of approximately 3,000 people. Both Huangpu River and Suzhou Creek, which flowed nearby, were predicted to reach their second highest crests in recorded history as a result of the nearby Prapiroon. More than 100 flights departing or arriving at Shanghai Pudong International Airport and Shanghai Hongqiao International Airport were either delayed or cancelled. Nearby ships were brought into temporary confinement in the Port of Shanghai.
