EURO hops on board and agrees with GFS on a possible typhoon around the Northern Philippines 8/9 next month.

GFS continues with an uptick in activity with 3 TC's first half of October.

Pretty good agreement on the next TC to develop on the 2nd of October.

Icon peak 984 mb

NAVGEM peak 961 mb

CMC peak 985 mb

JMA

So far nothing from EURO. It does show a closed low but no strengthening.

GFS had a strong typhoon but has backed down since.

It seems to form as early as Saturday, so it’s not totally in fantasy land.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

An active monsoon pattern is setting up over the Marianas with the recipient system right behind.

GFS solution past 7 days seems dubious to me. A monsoon gyre in the tropical WPAC in October?

Our calibrated model blend suggests a 40% chance of tropical storm formation in the South China sea during Week-2, so a moderate risk has been posted.

The globals are indicating a significant TC may develop around the 10-11 and impact the Batanes Islands off the Northern coast of Luzon and into China.

GFS is the most aggressive.

I'd be wary if i was in the Philippines.

Past nina events have featured an incredibly record breaking typhoon (+155 knot) impacting the Philippines in October especially after the first week of the Month. Angela in 1995 hit in November.

Examples:

Zeb 1998
Megi 2010

Some pretty strong signals from GEPS and GEFS for more activity during the month.
