Today's rainfall/weather update for the #NorthAfrica #HornOfAfrica and #MiddleEast follows.

The short version is that the peak of the rainy season may have passed, but there are signs of another Indian Monsoon surge coming in 10-12 days in long range forecasts.
Here is the long-range GFS model PWAT forecast for the Indian Monsoon. Towards the end it strengthens and we see high levels of moisture heading for the #HornOfAfrica.
Here is a big picture view of the greater region including all the areas that this weekly bulletin will cover.

A review of the past week showed that Sahel-Sahara rainfall has continued, as has rainfall in northern Sudan. The northerly rain is however not particularly heavy.

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.

🧵I love #football

Have done since the 1980's ⚽️

Nowadays though, the off-field stuff seems to get as much coverage & column inches as the game itself 🗞️📺📱

Competition isn't just about trophies - it's about eyeballs, soft power, geo-politics, PR and #money

Quick tale...
Did you see that news report from the #US this week about the #billionaire financier #TomBarrack being arrested? ($250m bail)

In the weird (but fun) world we live in, that incident ties to #NewcastleUnited & the #PremierLeague

Say what?! 🧐

#FollowTheMoney #Networks #Power 💸
We have;

- Billionaires acting as back-channel diplomats (💰)
- Political actors orchestrating things but pretending they're not
- Qatar buy rights to #EPL for region
- Saudi pirate them #AJ #BeIn #BeOut
- SA try to buy NUFC
- Qatar say "No Way"

#Rights ✍️/👨‍👩‍👧‍👦

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.

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.]

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.

Today's Big Pictures provide a view of the entire planet today in three images.

1. The Atlantic
2. The Pacific
3. Asia

Sometimes its helpful to take a broad view and remember that we are all on this planet together. And that we share the one amazing life giving biosphere.
I found another #MonsoonBurst in the pipeline, this time over the Western Pacific. One which shows very clearly that weird weather is now a universal phenomena in the Northern Hemisphere. And it all started with another Typhoon...

Thread attached...

There are many different types of stone structures in #KSA and it is easy to be confused by all the different shapes and what they were used for. In this thread, we will present the main types of structures our project has documented, the names we use, and some basic information. Image
Mustatil- these large structures are generally rectangular(ish) in shape and consist of two thick platforms at either end connected by 2-5 long walls. These are ritual structures dating to the #Neolithic i.e 7000 years ago. #MustatilMonday. Image
Kite- A kite is a large animal hunting trap. They are found in a range of different shapes and sizes, from simple V-shape constructions to much more elaborate structures, like those found around #Khaybar. These date from the #Neolithic onwards. ImageImage

The next two weeks promise to bring astonishing weather to both sides of the Red Sea & across the Sahara. In this weather bulletin I will explain what the models are forecasting.

Today's #NorthAfrica #HornOfAfrica and #MiddleEast rainfall forecasts follow.
In the image above we see part of Arabia and part of the #NileBasin storms - those which feed the Blue Nile/Abbay and the Tekeze basins the source of most of the Nile's flow.
Below we see:
1. All Nile Basin rainfall as of this evening
2. All of this evenings #ArabianStorms
The rainfall we see on both sides of the Red Sea comes mostly from the same source - the monsoon over the Arabian Sea, India and South East Asia.
A satellite image from this morning shows what we currently think to be the cradle of humanity. Where we all come from.

As the UNSC met tonight to discuss the #GERD storms continued to form over Ethiopia's highlands the source of the water which is currently filling the dam.

Today's #NorthAfrica #HornOfAfrica and #MiddleEast rainfall forecasts follow.
During the UNSC meeting. Ethiopia's water minister explained how this works. "The filling of the dam is part of the construction process.... When the dam is filled the water either flows over the dam or through the bottom outlets."
The Minister later spoke to media :

Q: (@AJEnglish): Why don't you stop filling the dam?

A: All dams are filling. Why? Because it is the rainy season. In fact it is good to protect from floods. We have bountiful water. It doesn't hurt anyone.

Rain forecasts will follow.

Thread contains rainfall update.
I jumped the gun calling the beginning of #GERD filling on1 July - as the big rainy season began.
Official news of filling came yesterday in the form of an objection to the filling from Egypt after being notified by #Ethiopia that it is underway.
#GERD filling is expected to be less than 13.5 Billion Cubic Meters as time ran out to raise the dam to the height needed to hold this amount of water.

When the filling is completed spilling over the center of the dam will resume as you can see in this image below from 2020.
