This thread is about Typhoon #INFA, a storm the likes of which the world has never seen before. Enduring, unpredictable, astonishingly wet, massive, slow moving, and never alone.

And 13 days after designation as a storm, #INFA is far from finished in its journey of destruction
My coverage of #INFA began on 14th July after it had formed into a visible and formidable storm, albeit not yet a Typhoon. But by then weather models already showed it was a significant threat.

Not simply as a storm but as a broader weather pattern.
The area in which the storm was expected to form showed up in the models earlier. Here we see it on the 10th of July in the GFS MLSP forecast. But it was probably there even earlier.

A global weather surveillance thread.

We begin in the West Pacific where Typhoon #INFA is now over China bringing rain to 100s of millions.
Here's a closeup of #INFA over the past 12 hours rain bands have now reached the already flooded Henan province.
Some early coverage of the impact here: nypost.com/2021/07/26/chi…

Including more harrowing video of flooding.

This week's rainfall forecasts for the #HornOfAfrica, #NorthAfrica and the #Middle East follow.

Image: Typhoon INFA over China showing the lights of Tokyo where the world is gathered to celebrate youth & excellence and the unity of the nations of the world at the Olympics.
Here we see Japan again and tropical storm #Nepartak which is on route towards the Olympics.

#Nepartak is a child of #INFA's gyre and you can see an atmospheric river coming from #INFA's outflows which leads directly to her.
This weekly thread is the sequel to the daily threads published April-July in solidarity with the efforts to complete the 2nd filling of the #GERD dam under difficult circumstances.

There hasn't been a clear view of the #GERD in the past week sadly, just a glimpse.

This animation shows 24 hours in the life of three storms in the West Pacific. The remnants of former Typhoon #Cempaka bottom left, Typhoon #INFA in the middle and TS #Nepartak far right which is headed to Japan.

Shangai is already receiving rain from In-fa, 650kms away.
A truly extraordinary storm. Maybe illustrative of what tropical storms of the future may look like.

#INFA developed slowly, moves slowly and is not particularly strong, but he/she is orchestrating rain catastrophes from 100s of KMs away in Shangai the Phillipines and Japan.
A big high resolution photo of INFA from this morning from @NASA WorldView. This is a truly huge storm.

A brief pictorial thread of parts of the northern hemisphere where extreme or unusual weather phenomena are underway.

Starting with #eastasia #infa & #3rdStorm which seems to have initiated formation. This is the storm which will crash #Olympics2021, shortly after the opening.
The 1st animation is 120 hours. This version goes for 11 days longer. As on #infa’s path beyond 120 hours, what happens beyond July 26th is pretty uncertain. #infa is also continuously not behaving as expected, totes normal for a heat engine of this magnitude.
Heading west a few thousand miles the lingering impact of the #ArabianMomsoonBurst is set to continue for some time bringing thunderstorms to the Arabian peninsula on a daily basis. See @Arab_Storms for video reports.

#INFA and a widening gyre.

July 22nd #Japan #Olympics2021 weather update, rain, wind, rain and more rain. This is not looking at all ok.

TL/DR: the model forecasts for East Asia have changed. And gotten significantly worse.
Here's a high resolution satellite image of Typhoon #INFA which is continuing to defy all predictions.

But the potential impacts of this storm both for those in its path and for the wider region are getting steadily worse.
Yesterday's thread can be found here >>

TL/DR the only hope at this point is that the models can't compute this right, and what they say will happen doesn't.

It's now time for prayer, and for Japan to prepare for widespread catastrophic rainfall.

Two typhoons getting closer and closer to each other. #INFA on the right is sucking the much smaller #Cempaka into its orbit. Sucking up all its outflow and chucking it out east.

The pair of typhoons current winds are fixed by JTWC at 70 and 65 knots at 06Z.
Here are the current warning graphics from the JTWC. ImageImage
#Cempaka is a midget Typhoon (1). Spinning like a top south west of Hong Kong.

Disregarding its size, #Cempaka is directing rain from Hanoi to Taiwan (2). The forecast (3 & previous tweet) shows Cempaka moving west in a loop, but this hasn't started yet. ImageImageImage

ECMWF ensembles showing the Fujiwhara effect between Typhoon #Cempaka 🌼 and Typhoon #Infa 🎆 as the two storms were forecasted to move around each other 🌀
That is one big monsoon gyre circulation over the northwest Pacific, formed by converging easterly trade winds and westerly monsoons. It gave birth to #Cempaka and #Infa. It might give birth to more typhoons.
Typhoon #In-fa has an eye in formation this morning (meaning: "fireworks" in Cantonese 🎆 name origin: Macao). Improving structure despite some dry air issues. #In-fa is forecasted to detach from its monsoon "tail" and continue to intensify while moving towards Taiwan.

Absolute scenes in South China Sea.Track forecast for Typhoon #Cempaka shows how weird set up of 2 typhoons in the same space is expected to resolve itself. Once #FabianPH / #INFA gets close it will going to drag Cempaka back out, with #Taiwan caught in between.

Typhoon #Cempaka rapidly intensifying while drifting slowly offshore of Guangdong Province, China (#Cempaka name meaning: a type of tree with fragrant flowers 🌼 name origin: Malaysia)
#Cempaka has reached 65 kts, 977 hPa per JTWC and 38 m/s, 965 hPa per CMA, despite initial expectations to remain a tropical storm. The land-sea surface friction contrast has caused #Cempaka's most intense convection to locate in the SW quadrant with a slightly elliptic eye. Image
My idealized simulations showed the predictable patterns of such asymmetry induced by friction, and their possible contributions to near-shore intensification of TCs👇 Image

Today's #FabianPH #INFA, #Olympics, #Olympics2021 disruption update thread.

See yesterday's thread below.

TL/DR: There is a significant typhoon/extreme rainfall threat to Japan in the opening days of the Olympics.
Here's a view of the two storms, #FabianPH / #INFA whose interaction is forecast to produce a 3rd storm in 4 days time which was forecast yesterday to arrive in Tokyo two days after the Olympics opening.

#Olympics, #Olympics2021
In the latest GFS 1hourly simulation model the solution remains the same as of today. A large typhoon like low (in terms of water content) will make landfall in Japan and stay over the country for some time bringing torrential rains during #Olympics2021

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
