The second typhoon in recent weeks is set to strike Japan and is causing concern for various reasons as it prepares to make landfall.

Typhoon Roke brought evacuation orders and fears of floods to Nagoya city in central Japan last night as it continued to approach the main island of Honshu on a course toward the crippled Fukushima Dai-Ichi nuclear plant.

More than 1 million people in Nagoya have been advised to evacuate because of Roke and almost 80,000 have been ordered to leave due to flood risk, said Katsuya Kobayashi in the city’s disaster prevention center.

That’s more than double the numbers for typhoon Talas earlier this month, which dumped record rainfall on southern Japan, causing mudslides and floods that killed 67 people and left 26 missing.

Talas was the deadliest storm to hit Japan in seven years.

“The major difference between the two typhoons was Talas was slow-moving over the Kii peninsula, dumping rain in the same area, while Roke is fast moving,†Kenji Okada, a forecaster at the Japan Meteorological Agency, said. “Roke is bringing strong gusts and dumping rain in a wide region.â€

The eye of Roke, categorized as “strong†by the agency, was about 928 kilometers (575 miles) southwest of Tokyo at 3 p.m. local time today. It was packing wind speeds of 144 kilometers per hour (89 miles), with gusts of 216 kilometers per hour.

The typhoon, moving northeast at 15 kilometers per hour, is forecast to take three days to pass over Japan and its storm warning area is due to cover most of the country in that time, according to the meteorological agency’s website.

Japan Airlines Co. canceled 49 domestic flights today as of 6 p.m. because of the typhoon, according to the company’s website.
