He stressed that this pattern of heavy rain will continue today and intensify from around 8 p.m. to 8 a.m. on Saturday, when the typhoon is at its closest. Lin predicted that rain is likely across the country throughout the day today, with extremely heavy rain probable in the north and mountainous central and southern areas.
Lin said that waves have continued to increase in size, with coastal areas of Matsu and Hualien reporting waves over four meters high. He warned that as the storm's wind circle nears coastal areas, northern and eastern Taiwan could see waves in excess of six meters.
Lin strongly advised the public to avoid any activities near coastal areas today and Saturday.
