THE WESTERN NORTH PACIFIC — KOGUMA STRENGTHENS TOWARD A TYPHOON

Koguma is forecast to strengthen rapidly into a typhoon over very warm open water within about 60 hours. It moves west, then turns north, threatening no land.

2 turning points on record since Oct 6.

Two oceans trade places — the Atlantic's first storm in weeks forms at its record, as the Pacific's storms fade over open water.

The Pacific reshuffles — Choi-wan turns extratropical and Nolo decays, while Koguma heads for typhoon strength, all far from land..
