A strong typhoon is bearing down on Japan and has Tokyo in its sights.

Typhoon Phanfone was churning north Sunday toward Japan’s southern tip with sustained winds as powerful as 185 kph (115 mph).

The storm is expected to then turn to the northeast and hug the country’s southeastern coastline over the next day.

“We’re talking torrential rain and also significant wind,” said Ivan Cabrera, a meteorologist for CNN International.

Phanfone is forecast to weaken before it makes landfall near Tokyo early Monday, with sustained winds as strong as 139 kph (86 mph), according to the U.S. government’s Joint Typhoon Warning Center. That’s the equivalent of a Category 1 hurricane.

NASA’s Earth Observatory tweeted a photo Saturday showing the large typhoon’s bands swirling out from its center.

The storm’s powerful winds could bring storm surges to bays along the southeastern coast, including Tokyo Bay, Cabrera said.

Mudslides are also a risk in mountainous regions, with the typhoon expected to dump 100 millimeters to 200 millimeters of rain on some areas.

Officials have expressed particular concern about the situation at Mount Ontake, a volcano that suddenly erupted last weekend, killing dozens of hikers.

Search efforts have been suspended, because of the approaching typhoon, for around a dozen people who remain missing on the volcano, the Japanese news agency Kyodo reported.

The high accumulation of volcanic ash on the mountain, combined with the forecast of heavy rain, increases the danger of mudslides.
