Kilo was first classified as a depression almost 700 miles south-southeast of Hilo, Hawaii, on August 20.
While, thankfully, never getting its convective act together in time to pose a threat to Hawaii, Kilo finally did so roughly one week later well west-southwest of the islands, intensifying to Category 4 strength.
And it's not done yet.
Instead of turning north, getting caught by the jet stream, and turning into a post-tropical storm over the North Pacific Ocean, high pressure aloft over the western Pacific to the east-southeast of Japan is expected to eventually send Kilo westward into next week.
That could bring Kilo uncomfortably close to the Japanese mainland next week, though eventually the jet stream should catch up with Kilo and turn it back northeast.
This means Kilo may live as a strong typhoon well into next week, 10 days from now, or longer.
