Hong Kong has raised its storm warning to Typhoon Signal 8 as Super Typhoon Yagi approaches, leading to anticipated flight disruptions throughout Friday. The Hong Kong Observatory reported that the typhoon, with maximum sustained winds equivalent to a Category 4 hurricane, is currently located about 330 kilometers south of the city. In preparation, schools have been ordered to close, and the local stock exchange will cancel its morning trading session until the alert is lifted. Authorities in southern China are also taking precautions, with Hainan Island issuing its highest emergency response level due to fears of severe impact from the storm.
