The tropics remain full of life in the West Pacific as Tropical Storm Leepi takes aim at southern Japan and South Korea into Wednesday night.

Once a Severe Tropical Storm, Leepi has weakened to a weak tropical storm as of midday Wednesday.

The small size of Leepi limited the radius of its impacts as the storm made landfall on Kyushu on Wednesday morning.

Kyushu will continue to face heavy rain and gusty winds, with some downpours and strong winds lashing eastern Shikoku.

Strong winds will be capable of causing tree damage and power outages while heavy rainfall will increase the risk for flooding and mudslides.

Travel disruptions are expected to linger into Wednesday as conditions improve during the day across Kyushu.

Conditions improve on Wednesday across southern and western Shikoku as well.

Local flooding and travel disruptions are the most likely impacts across Shikoku.

Leepi is expected to dissipate by Wednesday night or Thursday morning as it interacts with a larger storm system moving across the Sea of Japan.

Moisture from Leepi will be drawn northward into the storm which will drench parts of southeast South Korea through Wednesday night.

Downpours will overspread northern and western Honshu Wednesday night with the heaviest rainfall expected on Thursday.

Flash flooding and mudslides will be a concern across western and northern Honshu as well as Hokkaido during this time.

A bit of rain will fall across Greater Tokyo Thursday night into Friday morning; however, no flooding or significant impacts to travel are expected.

Elsewhere, Tropical Storm Rumbia has developed over the southern Ryukyu Islands, which is expected to impact the Ryukyu Islands and eastern China later this week.
