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.

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.
#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.

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.

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.
And the corresponding two JTWC Warning Graphic / Track Forecasts
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.
My idealized simulations showed the predictable patterns of such asymmetry induced by friction, and their possible contributions to near-shore intensification of TCs👇
