The final wave of low pressure in a series of storms to affect areas from eastern China into Taiwan, South Korea and Japan will bring more rainfall through Sunday.

Low pressure is expected to track over Honshu, the main island of Japan, on Saturday and eventually reach Sapporo Sunday into Sunday night.

As the storm tracks northeastward, the heaviest rainfall looks to target Japan. This is bad news for many areas that have already received heavy rainfall earlier this week. The combination of recent rainfall and an additional 1.00-2.00 inches (25-50 mm) from this storm will lead to potential flooding across all of Japan. There will also be a threat for mudslides across and near the higher terrain.

High winds will also be a problem from the Korean Peninsula into Japan as the storm strengthens and passes over the region. Winds over 40 mph (65 kph) will be possible, especially over the higher terrain and near the coast.

The Korean Peninsula will be on the northern edge of this storm with generally 0.25-0.75 of an inch (6-19 mm) expected in South Korea and lower amounts across North Korea. No widespread flooding problems are expected from this storm system.

The associated cold front will press southeastward over the northern Philippines on Sunday, enhancing showers and thunderstorms there.

Heavier rainfall is expected across Taiwan where a general rainfall amounts over 2.00 inches (50 mm) will be possible through Saturday night bringing the threat of local flooding problems.

A brief stretch of dry weather is expected across eastern China on Sunday and Monday before another storm system brings the threat for more heavy rainfall to the region which could again lead to flooding problems.
