Yutu

Yutu becomes the 6th Cat 5 of the year in the WPAC. Incredible.

During the next two weeks, there is a moderate potential for additional tropical cyclone development near or east of the current location of Typhoon Yutu.

Not seeing anything developing the next few days according to the models...KW and MJO still raging. Amazing what that can do with el nino with the strongest TC of the year...Yutu.

The record is 13 from the 50's. 12 from the 60's. (Recon)

2017 is the first year since 2011 to not feature one and breaks a 4 year streak.


Let's add Super Typhoon Yutu...

Kong Rey should be on the list.

Since 1987, typhoons have not become weaker. It's the loss of recon and that is making the WPAC look weaker.

Look at the other basins having one of their most intense hurricanes since 2010 occurring yet the WPAC is still stuck with the old record. Sad.

There has been little change to the overall thinking regarding the evolution of the global tropical convective pattern. The indices are being pulled back to the West Pacific, partly due to the base state, and partly due to powerful Typhoon Yutu. The storm, which devastated parts of the Northern Mariana Islands, is helping to generate a substantial westerly wind burst near 140E. Dynamical model MJO index forecasts propagate this signal eastward to the Western Hemisphere, and back to the Indian Ocean, although interference with the low frequency state reduces confidence in this solution.

Recent dynamical model forecasts depict an increase in convection along the East Pacific ITCZ, and there is an increasing potential for tropical cyclone formation well south of Mexico. Additionally, confidence in tropical cyclone formation is substantially higher over the central Atlantic, well northeast of the Lesser Antilles. The outlook has been updated to reflect these increased potentials. Fewer GEFS ensemble members spin up a new tropical cyclone east of Guam; however, given the substantial westerly wind burst near New Guinea, moderate confidence for cyclogenesis is maintained and shifted southwestward. Although not included in the updated forecast's domain, dynamical models continue to indicate a potential for tropical cyclone development over the Arabian Sea.

WPac ACE is now at 324.195. Excluding the obviously hyperactive 2015, this is the highest number for the basin since 2004. An active season for sure, but the last decade or so of typhoon seasons has been particularly below average. This is only the third >300 ACE season since 2006 (and 2012, the other season aside from this one and 2015, made it by less than a unit), and since that time, there has been more seasons <200 ACE than >300. Those seasons are 2008, 2010, 2011, and 2017, by the way. Quite a contrast to the 1990s, when five seasons had >400 units of ACE.

The west Pacific is expected to become more favorable for tropical cyclone development by mid-November if a Kelvin wave progresses east ahead of the MJO entering the Indian Ocean.

Beginning with Jebi's classification in late August, we've only seen 7 JTWC systems/6 JMA named storms, but over half of the season's ~330 units of ACE thus far. That span featured a JTWC depression (29W), a weak tropical storm (Barijat), and five category 5 super typhoons. This has been an impressive El-Nino type stretch recently.

Seems like the ensembles and models are liking an area of disturbance from the Central Pacific to develop west of the dateline, southeast of Guam. Another long tracker?

The name Yutu has finally become a category 5, next name is Toraji, can Toraji finally become a category 5 too? 2018 is still 4 super typhoons away and 4 category 5s away from 1997's record

Still alot of uncertainty. EURO and GFS keeps it weak as it moves towards the Marianas.
