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.

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.

Dear Ethiopian Twitter followers, and those from the wider region I have been covering with rainfall forecasts for the past few months.

I will no longer be doing these daily. But that does not mean they will stop altogether, as I am hooked on the changing weather in your region.
The image above is this from this morning's satellite pass. And it was the only bit visible through he cloud near the Ethiopian highlands which have been the focus of this effort. I suspect all of Ethiopia was covered but we can't see the bit in the black strip, not certain.
The reason for stopping the daily forecasts is, of course, the filling of the #GERD, that was why they started. But they led to so much more.

Today one of the things I originally started looking for happened in a spectacular way. This is a live rainfall image from 8.15 am today.

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

Congratulations to Ethiopia and Ethiopians everywhere on today's completion of the 2nd filling of the #GERD. It has been a great honour to follow along during this moment.

Today's rainfall forecasts for #NorthAfrica, #HornOfAfrica and #MiddleEast follow.
In honour of the #GERD we will change up the order of today's bulletin and get right to the most important issue, rain over the #Abbay basin, which due to its great quantity and consistency made this possible over such a short time period.
But first a brief explanation, as when it comes to the GERD not all rainfall counts. The first image here shows the path of the #BlueNile / #Abbay from Lake Tana to Khartoum where it meets the White Nile and becomes "The Nile".

The presentation of the #ArabianMonsoonBurst has changed dramatically today with the consolidation of activity over the Arabian Peninsula into a single huge storm which is currently moving into the Red Sea over Makkah and Jeddah.

Today's rainfall forecasts follow.
The scale of the storm over Islam's holiest city is huge, larger than France. Two more huge storms loom over the greater region tonight. One on the Iranian Gulf coast and another supercell thunderstorm complex over New Delhi/Rajastan, India, the size of the United Kingdom.
The last six hours in three animations, first India which is experiencing a massive monsoon day today in the north.

[Here the initial frames show a blank SEA as their was a satellite data outage.]

There has been a sharp increase in discussion of climate change weather extremes in the context of the flood calamity in Western Europe, wildfires in the North West US, and the #ArabianMonsoonBurst

This thread looks at the big picture right now. What's next?
The image above from @Meteoblue shows most of the Northern Hemisphere & rainfall at the moment. The intense blobs of colour indicate high rainfall from thunderstorms.

What is immediately apparent looking at this is that there is an immediate issue now in the West Pacific.
What will soon be Typhoon In-Ha is forecast to make landfall in Taiwan and then stall bringing massive rainfall to the Philippines, China and Taiwan.

There is second tropical storm to the left of what will soon be In-ha which is simultaneously bringing extreme weather to HK.

Today is possibly the apex of this #ArabianMonsoonBurst which began several days ago now. It's hard to imagine it getting bigger than this.

Today's #NorthAfrican #HornOfAfrica and #MiddleEast rainfall forecasts follow.
The animation above is for 12 hours hence the arriving and departing light effect. As always the engine behind this is the Indian Monsoon which you can see here this morning gathering strength.
A close up from the end of today shows how the big storms over #SaudiArabia are generating new atmospheric rivers of moisture, or plumes, over the Sahara, you can see these top right.

[Note: Atmospheric rivers are often invisible, this one becomes visible as night falls.]

This is a long statement, probably a bit too long, but interesting and important. My reading is that Ethiopia has not yet decided to abandon the unilateral ceasefire, but that frustration is going, both with the TPLF and their ongoing offensive....
... and with ongoing one-sided diplomatic/media understanding of the Tigray conflict.
The @NYTimes story from @declanwalsh (see below) has become a lightning rod for public and government concerns that Ethiopia is not being listened to or being given due respect internationally.

The magnitude of #ArabianMonsoonBurst is now apparent. A major storm is about to cross the Red Sea and arrive in the #HornOfAfrica. Behind it are two enormous super-cell thunderstorms.

Today's rainfall forecasts follow.
The rain activity shown in the @zoom_earth animation preceding is only radar based, Saudi radar, and in this case is complementary to the @Meteoblue satellite rainfall estimates you see below. There is likely significantly more rainfall in this than you see here.
Here we see India (the heart of this Monsoon), this morning to 10am East Africa Time. I.E. around seven hours ago.

It's raining cats and dogs in the highlands northern Ethiopia tonight. Across all of Tigray and south into the #Abbay basin which is busy filling the GERD. The #ArabianMonsoonBlast is getting into gear now but it is far from over.

Today's Rainfall forecasts follow.
The Bay of Bengal and Arabian Sea are ultimately responsible for all of this and so we begin with a couple of satellite images of them today. I will post another picture of the #GERD as soon as it reveals itself from under the clouds.
Here's a rainfall map from @Meteoblue which can be followed live at >> meteoblue.com/fr/meteo/curre….

Mekele isn't right under the rain but Aksum and Shire are. Hopefully this will slow down the warriors.
