STS Halong Leaves 2 Dead and over a million displaced (Sunday Afternoon Update)

Posted on August 10, 2014 by Robert Speta/ westernpacificweather.com

Severe Tropical Storm Halong tore across Western Japan Sunday Afternoon bringing torrential rain and gale force winds. Now the storm is moving out over the sea of Japan but outer rain bands will continue to impact Japan through Monday.

Two deaths have now been a direct result of the storm, over 1.6 million people have been displaced and millions of dollars in damages have occurred due to flooding.

NHK is reporting a women died due to flood waters in the Takamatsu River Sunday. Saturday morning a 78 year old man was swept away in rising flood waters in Iwate Prefecture.

Furthermore this weekend is the Obon weekend in Japan where millions of people are traveling to visit the graves of ancestors.  With over 400 flights cancelled and Shinkansen lines shut down many of those people are stuck at airports and stations waiting for service to resume.

To cap things off a 6.1M earthquake sent a scare through residents of northern Japan around 1PM JST. The image to the right shows typhoon warnings being aired on NHK with the earthquake warning over laid.

The disaster unfolding across Japan should come as no surprised though, this storm has been slowly working its way north towards Japan for nearly a week now. Following Tropical Storm Nakri which brough torrential rainfall and then a stationary front that lingered over Japan this week the grounds of Shikoku, Kyushu and Western Honshu were already saturated and unable to bring in any more rainfall.

Now in the past 48hrs along Typhoon Nakri has dumped well over 1,000mm in parts of Kochi Prefecture on Shikoku. While other parts of western Japan have seen above 800mm in total. You can find this information at this link. 

For only the second time in 2014 JMA has issued an emergency warning. It was issued in Mie Prefecture for ground loosening rains. This is the highest level on JMAs warning scale and indicates a very serious threat to the loss of life.

In Shimamoto near where Videographer and Westpacwx Team Member James Reynolds is there has been reports of damage to homes after rivers in the Shimamoto river swelled when Halong came ashore. You can follow his twitter account as he documents the storm there below.

Western Pacific Weather first reported on this threat a week ago after the storm passed Guam and started tracked towards Japan.

–

Halong will continue to track over the Sea of Japan Sunday Night through Monday pulling in moisture from the south and eventually getting sheared to the east. What this means in short is heavy rainfall can be expected across Central and Northern Japan to start off the work week.

Over 100mm even in to the Tokyo area is possible as well. Around noon on Sunday Tornado Advisories were issued in the Tokyo Metro area due to strong cells rolling through the city.

For the most part the weather in Tokyo should not be to severe but it will be enough to cause delays on the roads and even localized flooding.

 

COULD RUSSIA GET HIT BY A TYPHOON OR A TS?

The bigger question is could the Russian Far East get impacted by Tropical Storm Strength winds, that seems like a more likely yes, but will Halong maintain its tropical characteristics farther to the north is unlikely. We will continue to track the progression of the storm but even Vladivostok could be looking at rough conditions by Monday and Tuesday of this coming week.
