Haishen became a Super Typhoon yesterday, but did not become a Category 5 super typhoon. Instead, it peaked as a high end Category 4 super typhoon, with sustained winds of 155 mph (250 kmh) and gusts of up to 190 mph (306 kmh). However, now it will start to weaken gradually as wind shear increases, and colder ocean temperatures will soon be underneath Haishen. It is approaching the islands of Amami Ōshima and Kikaijima, where it could still deliver Category 4 winds to those islands. It will move northwards and affect Kyushu Island of Japan, where it could deliver strong winds to coastal areas and drop lots of precipitation on the island. Then Haishen will make landfall on South Korea, possibly as a Category 2 typhoon.
Typhoon Haishen follows Typhoon Maysak, which smashed into the Korean peninsula on Thursday, leaving at least two dead and thousands temporarily without power.
