This attached thread from this morn looks at Typhoon #INFA ("In-fa" TS09W) which is poised to be extraordinarily disruptive to the 2021 Olympics in Japan.

It has since come clearer what we can expect from a dangerous and unusual weather system developing over the West Pacific. Image
This is the story of three storms rather than one, but IN-FA will play the starring role.

1. TD10W currently menacing Hong Kong
2. "IN-FA" which is technically still TS09W (fmrl. #invest98w)

& a 3rd storm which models forecast TD10W & IN-FA will bring about in 5 days time. Image
Here's the latest satellite imagery of TD10W (left) and #INFA (right) ImageImage

Ongoing coverage of Invest 98w, currently south east of the Phillipines and forecast by the GFS to make landfall in China, after formation and swift strengthening over the next few days. Here is a picture as the Sun came up over the west Pacific ocean.
Yesterday's thread linked above.

This cyclone candidate is interesting for two reasons: 1. intrinsically as a potentially dangerous storm and 2. because of the wider set up around it which is detailed in yesterday's thread.

This animation is from this afternoon.
Meanwhile we have a new cyclone candidate in the Atlantic also, #Invest99L which is also stationary and presents visually in a similar manner to #Invest98w. It is developing in a similar spot to the first Tropical Storm of the 2021 Hurricane Season, Ana.

This GFS weather model setup in the West Pacific (next 16 days) looks pretty hazardous beyond #Invest98W which is forecast to become a cyclone within the next three days.
Here as still images.
- 20 July - Impacting China and Southern Japan
- 21 July - Landfall China
- 24 July - Three lows near Japan (1 cyclonic)
- 30 July - Two new lows in typhoon formation zone
The PWAT forecasts show a very significant increase in precipitable water over this period. This is the first 120 hours from GFS Hourly model.
