Two western Pacific tropical storms will affect the Far East during the next few days.
Tropical Storm Maliksi will brush eastern Japan Wednesday into Thursday, narrowly sparing the country a blast of severe wind and rain.
Needless to say, a more westerly track could bring much more significant impacts, both at sea and on land.
Far to the south, meanwhile, Tropical Storm Gaemi, gathering steam as midweek, will target central Vietnam with a potential burst of flooding rain.
Maliksi was centered about 600 miles south of Tokyo as of Wednesday afternoon, local time. The broad storm, tracking northward at nearly 25 mph, had high sustained winds of at least 55 to 60 mph, the Japan Meteorological Agency (JMA) said.
During its nearest brush with eastern Honshu, late Wednesday night and Thursday, the outer heavy rain and strong winds of Maliksi will reach the immediate coast east and northeast of Tokyo.
Late in the week, Maliksi will become a powerful post-tropical storm, eventually targeting the Aleutian Islands and Alaska Peninsula of Alaska.

Meanwhile, the smaller Tropical Storm Gaemi was still hovering over the South China Sea west of northern Philippines. The center was located about 230 miles west of Manila as of Wednesday afternoon, local time.
Highest sustained winds about the tropical cyclone were about 60 mph, according to official forecast advisories.
Gaemi was forecast to begin heading westward, away from the Philippines, on Thursday. Typhoon status was forecast for Gaemi beginning Thursday, according to the Joint Typhoon Warning Center (JTWC).
A landfall on central Vietnam was expected for late Friday into Saturday.
Owing to the topography, a landfalling tropical cyclone would be expected to yield torrential rainfall, threatening flooding.
Normal rainfall for the very wet month of October is more than two feet in parts of central Vietnam. Tropical cyclones sometimes dump as much rain within 24 to 48 hours.
The plum rains are known as "meiyu" in China, the "baiyu" or "tsuyu" in Japan, and the "jangma" in the Koreas. The heart of the plum rain season stretches from early June to mid-July, with a tendency to shift south to north across the affected area.
In the wake of the mid-June cloudbursts, most of Pakistan to northwestern India last week saw a return to dry, hot weather typical of the weeks leading up to the Monsoon onset. It was as if the Monsoon withdrew to its "normal" position for the latter half of June.
The 38.5 degree C (101 degrees F) reading Tuesday in Ajaccio, Corsica, may have been tops in Europe.
Monsoon Onset was June 13th, 2013, in Delhi, almost two weeks earlier than average. The June 15th onset at Karachi and Islamabad was more like three week ahead of schedule.
In Pakistan, hit-or-miss downpours missed the Sindh capital, Karachi. One did hit Pad Idan, where it left 60 mm of rain Wednesday. This was more than 20 times greater than the normal June rainfall.
It is still possible that this scenario is over wrought as to the intensity and spread of rain in Pakistan and northwestern India. However, it is the hunch of the present forecaster that some very unusual weather is going to unfold in the Subcontinent during the next week!
