Less than a week after being hit by the largest typhoon in a decade, Tokyo is bracing for another strong storm that will likely reach the area Saturday, and it may get merged with an even stronger approaching tempest.

Though less powerful than Typhoon Wipha, incoming tropical cyclone Francisco is rated as "strong," the Meteorological Agency said. But on a possible collision course is Typhoon Lekima, considered "more fierce."

As of 3 p.m. Wednesday, Typhoon Francisco, the 27th this year, was located about 180 km south of Minamidaito Island, east of Okinawa, heading northwest at a speed of 15 kph.
