Dangerous Typhoon Roke rapidly strengthens, to rake Japan
By Jason Samenow
Typhoon Roke from the the Japan Meteorological Agency’s MTSAT weather satellite on September 20, 2011 at 0730z. ( NOAA ) Since Monday, Typhoon Roke
has undergone rapid intensification and presents a clear danger to large parts of Japan. Maximum sustained winds have increased from 80 to 130 miles
per hour in just the last 24 hours. Roke is equivalent to a high-end category 3 or low-end category 4 hurricane.
Located about 500 miles southwest of Tokyo, the storm is expected to charge northeast, making landfall near Honshu - just southwest of Tokyo,
Wednesday afternoon local time (or late tonight EDT).
On that track, Tokyo would likely be impacted by the storm’s most severe northeast quandrant and contend with wind gusts over 74 mph. The Original
Weather Blog writes: If the ... forecast verifies, Tokyo will see a potentially devastating combination of storm surge, flooding rainfall and strong,
damaging winds.
Travel to and from Tokyo will almost certainly be severely disrupted Wednesday.
While the Joint Typhoon Warning Center predicts some weakening prior to landfall, Roke won’t have much time to do so given its rapid forward motion.
At present, the JTWC reports that the storm’s convective structure has “quickly improved.”and that it contains a well-defined “symmetric
eyewall surrounding an 18 nautical mile round eye.”
AccuWeather says the storm is currently producing waves to 26 feet. A storm of this intensity is likely to generate a potentially deadly, destructive
storm surge. Ahead of the storm, the BBC reports evacuations are underway:
More than a million people in central and western Japan have been urged to leave their homes as a powerful typhoon approaches.
Flooding rain is forecast to cause additional problems reports Xinhua.net:
Japan’s Meteorological Agency (JMA) warns that heavy rainfall brought by the approaching typhoon Roke could trigger landslides and floods in western
and central Japan, parts of which saw hourly rainfall between 30 and 40 millimeters on Tuesday evening.
AccuWeather expressed concerns about the storm’s impacts on the Fukishima-Dai-Iche nuclear plant:
Workers trying to control leakage into the basements of nuclear reactors at the Fukushima-Dai-Ichi power plant may need to be evacuated ahead of the
storm, with more than 6 inches (150 mm) of rain expected to fall over the reeling prefecture.
