After drenching the Philippines and Taiwan, Tropical Rainstorm Danas unleashed heavy rainfall and gusty winds on parts of South Korea and Japan from Friday night into Saturday.

Danas then made landfall in western South Korea on Saturday before emerging into the Sea of Japan (East Sea) on Sunday.

Locally heavy rainfall will continue across much of South Korea and southwest Japan through Sunday night, with additional rainfall of 50-100 mm (2-4 inches) in many locations.

Several hours of heavy, tropical rainfall is likely to fall on already saturated ground, increasing the risk for mudslides.

Areas near and east of Danas' track in South Korea could have damaging wind gusts. Wind gusts associated with Danas could reach an AccuWeather Local StormMax™ of 80 km/h (50 mph).

The exact track of Danas early this week will determine how far north the flooding threat will extend. However, all residents of southeastern Russia should monitor this storm closely as more details become available in the coming days.

By this time, it is possible that Danas will have lost most of its tropical characteristics and much of the threat will have diminished.

Danas began as a tropical depression in the Philippine Sea on Monday morning and quickly strengthened into Tropical Storm Danas east of Luzon by Monday night. In the Philippines, the storm is known locally as Falcon.

Flooding was reported across the Philippines with the heaviest rain falling across northern and western Luzon.

With the track of Danas staying east of the island, Taiwan avoided the heaviest rainfall and instead was hit with periodic showers and thunderstorms.

Rainfall of 25-75 mm (1-3 inches) was most common with locally higher amounts across the island.
