Elsewhere, a low pressure system located over the northern tip of Japan will exit into the western Pacific Ocean on Monday. As this system exits, wrap around moisture from the Pacific will trigger areas of scattered thunderstorms with light to moderate showers throughout Japan.
Meanwhile, significant instability due to another strong low pressure system will produce unsettling weather as it stretches through northeastern China and the Korean Peninsula. Abundant moisture from the Yellow Sea will enhance instability along this system, yielding to heavy amounts of precipitation and thunderstorms in between Nanjing and Jinan, China. Heavy downpours are expected to reach Seoul by early Tuesday morning.
For Australia, a broad area of low pressure will push moisture across the south-central and southwestern shorelines of the nation, creating a chance for showers along the coasts of South Australia, Victoria, and New South Wales. Light showers may reach into southeastern Queensland, falling near Brisbane. The remainder of Australia will see dry conditions to a dominant ridge of high pressure.
On this date in 1993, a 7.8 magnitude earthquake in the Sea of Japan triggered a large tsunami. Waves up to 90 feet tall swept away people and buildings. While 239 people died, a far more major diaster was avoided due to the Japan Meteorological Agency's timely warnings to residents and businesses.
