According to the JTWC Yagi is now a typhoon and moving SE at 1 knot, is that slow or what! :lol:

. Four to five days out it will be threatening Iwa Jima.

And we now have a typhoon. Forecast takes it very near Iwo Jima in 72 hours.
JTWC track is pointing close to Tokyo, though most likely a close recurve to the east. The JTWC track is further north than the JMA track, so a hit on the home islands cannot yet be ruled out, though Yagi is still a good week away.

yes, this might look like a closer call than Ioke was, and latest forecast still has it a 105kts only a few hundred miles off the coast

Yagi has duel outflow channels from upper-lows to it's southeast and to it's west. Dry air entrainment may hinder the intensifacation somewhat but will be interesting to watch these factors over the next few days.

Yagi is up to 100 knots now and Hurricane Bills post above mine shows a nice symetric system. JTWC peaks storm at 115 knots then begins weakening it as it approaches the Bonin Islands.

Recurve east of Japan is now in the forecast, though Iwo Jima still looks to be getting a direct hit from Yagi.

For comparison, the JTWC, hoever accurate they may be, has this intensifying to Cat 5 less than 12h before reaching Iwo Jima.
