Super Typhoon Trami exploded in intensity from a tropical storm on Saturday to the verge of Category 5 intensity on Monday. The storm is slowly moving northwestward, spinning closer to Taiwan and southwestern Japan.
The big picture: Super Typhoon Trami is expected to reach the equivalent of Category 5 intensity as it moves slowly over some of the warmest waters in the Northern Hemisphere. By Sept. 29, it will be nearing Japan's Ryukyu Islands and northern Taiwan. Given the track uncertainty this far in advance, the storm is considered a landfall threat to Taiwan.
