After drenching the Philippines and Taiwan, Tropical Storm 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 and will move across the peninsula before emerging into the Sea of Japan (East Sea) on Sunday.
Rainfall totaled 75-150 mm (3-6 inches) across much of southern South Korea and far southwest Japan through Saturday with more downpours on the way.
Locally heavy rainfall will continue across much of South Korea and southwest Japan through the day on Sunday with additional rainfall of 50-100 mm (2-4 inches) in many locations.
Locally heavy rainfall will continue across much of South Korea and southwest Japan through the day on Sunday 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 the ground, increasing the risk for mudslides.
While the primary concern with Danas will be flooding, Danas is expected to remain a tropical storm as it crosses the Korean Peninsula into Sunday.
Areas near and east of Danas’ track in South Korea could see 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 next week will determine how far north the flooding threat will extend. However, all residents of northern Japan and 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.
Despite the recently churned-up waters near the Philippines, this area will need to continue to be monitored for further tropical development into the weekend.
