Hurricane Arthur may have been, pardon us Jamie Dimon, a "tempest in a teapot" fizzling quietly in the Atlantic, but halfway around the world, a far greater storm is currently picking up speed and barreling toward Japan. As Reuters reports, Typhoon Neoguri, described as a "once in decades storm" is set to rake the Okinawa island chain with heavy rain and powerful winds. Typhoon Neoguri was already gusting at more than 250 km an hour (150 mph) and may pick up still more power as it moves northwest, growing into an "extremely intense" storm by Tuesday, the Japan Meteorological Agency (JMA) said. "In these regions, there is a chance of the kinds of storms, high seas, storm surges and heavy rains that you've never experienced before," a JMA official told a news conference. "This is an extraordinary situation, where a grave danger is approaching."
