Tropical Storm Muifa made landfall in North Korea today, bringing heavy rainfall and gusty winds, according to the Joint Typhoon Warning Center.

The storm, which was downgraded from typhoon status on Monday (Tuesday NZT), came ashore in North Korea (this morning NZT) said CNN meteorologist Brandon Miller.

“It’s quickly losing its tropical characteristics and losing strength as we speak,” he said.

Four people died and two others were reported missing in Seoul, South Korea, where the storm passed Monday evening, the semi-official Yonhap News Agency reported.

In China, at least 490,000 people had been evacuated from Shandong and Liaoning provices in the eastern part of the country, Xinhua reported. No deaths or injuries were reported.

In Dalian, authorities were able to avert the spill of toxic chemicals from an industrial plant after 65-foot (20-meter) waves broke through a dike protecting the area and threatened to flood the plant, according to Xinhau. Workers dumped concrete and rocks to fill in the hole.

The plant contains cancer-causing chemicals used to make polyester film and fabrics, Xinhau said.
