October 2020 NWPac TC Tracks.

Unfortunately, early November offers no respite from tropical systems that have battered Philippines and Vietnam as Invests 92W and 93W are simultaneously developing near the Philippines.

JMA forecast VP to overspread the whole basin during the month and into December.

This season isn't done yet.

Incredible to think that this season is ongoing and yet people forget that the 2021 season is approaching!

2021 typhoon season starts in less than 2 months!

VP = Velocity potential?

Such rising air motion in the atmosphere tends to increase condensation and rainfall. Cannot rule out a TC.

Too early to worry about next season. The first quarter usually is the quietest. Strong TC's can still develop and has done so in the past.

Models are now quiet and the next activity looks to happen around end of November and into December unless something else develops.

What a way to end this *slow* season with 375 deaths so far.

Dynamical model MJO index forecasts favor continued eastward propagation, with a potential new Indian Ocean MJO event materializing during Week-2. Should this occur, conditions would become increasingly favorable for Indian Ocean tropical cyclogenesis during the outlook period, and may promote renewed West Pacific activity beyond the two-week outlook period.

CPC Tropical Hazards

Enough time for those waters to warm back up and warm even more.

If we're gonna go by GEFS we may see another spark of activity in this basin by the last week of November. I know La Niña/cold ENSO years don't usually extend the typhoon season well into December but it feels like this will be another case like in 2019 when we saw year-end typhoons like Kammuri and Phanfone.

Looks like Philippines and Vietnam will get a much-deserved break from TCs during the next 10 days or so. Risk of TC development in the area may increase again by the end of this month / early-Dec, depending if the MJO signal currently over western Indian Ocean stays strong as it moves east.

JMA has just released its best track for Typhoon Haishen - significant but reasonable changes as follows:

- TS upgrade has been pushed forward by 24 hours, consistent with ASCAT data. Intensities during the rapid development stage have also been bumped up.

- Peak intensity revised to 910hPa/105KT, corresponding to CI7.0 on the Koba scale.

- Intensities during the weakening stage have been smoothed.

The full best track:

The year is almost over but I guess there is one last hurrah of the WPAC season. I am kinda surprised that area east of the Visayas region in the Philippines is not yet tagged as invest.
