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.

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.

The convective storms over Ethiopia and Sudanese Nile Basins tonight is remarkably intense. Bringing massive amounts of rain across a huge area, including the #Abbay /#BlueNile basin, on the 4th day of #GERD filling.

In this wider view you can see the full size of today's rain areas which extended deep into Sudan later in the afternoon.
These two images are at sunset the sizes of the two large convective areas, the eastern one extends well north into Eritrea and covers Tigray and the entire #Abbay Basin. The first image provides an idea of size. Each storm area is larger than the UK and Ireland.
Heavy rains fell over the Horn of Africa today as the world turns its attention towards the area, following a tumultuous week since the election last Monday.

There was a second day of big rains over the horn today. In this image on the right hand side you can see the incoming water baring winds from across the Arabian Sea from the Indian Monsoon.

Here's a wider angle view. The water bearing mid-altitude jets provide much of the moisture that fuels the West African Monsoon, and its East African extension.

We have a stunningly clear image of the #NileBasin this morning from @NASA Modis from Cairo to Lake Victoria showing the impact of the April and May rains on the landscape.
In today's 10-Day North Africa rain forecasts the European @ECMWF model remains unconvinced about the impact of #WestAfricaWaterPlumes on the Sahara, which as you will soon see are once again having a spectacular impact on European weather.
We have another large #ArabianStorm which was not anticipated by the global weather models. And like those before it, it is fueled by the #WestAfricaMonsoon and a #WestAfricaWaterPlume. This time across the Red Sea in the vicinity of #Makkah.

The origin of this event is very similar to that which caused several days of extremely severe thunderstorms in #Oman earlier in the month. This animation is from May 18th shortly after it first appeared in the @zoom_earth satellite imagery.

This satellite image (@NASA Modis ) shows the area in the Arabian Sea which computer models indicate could generate two cyclones in coming days. You can see the latest GFS forecast runs for those cyclones in the attached thread.

First up today, long range @NOAA forecast models are now forecasting a cyclone may form in the Arabian Sea, providing a timely warning of the risk to those in the region. See thread here >>
The most important thing about these forecasts is to understand they are an early warning system about the possibility of a cyclone forming, not a forecast that one will do so.
If a threat materialises you will see official advice and warnings here >>

I am beginning to think that this sudden climate change business is getting a bit out of hand. Especially as nobody seems to be noticing except those in Yemen and Somalia watching their cars being washed away down the roads and rivers.
I have been tweeting a lot about the weather in the Horn of Africa lately.
Including asking for images of flooding from eyewitnesses.
I received a response on April 24th the day after the Norwegian Refugee Service published there article about droughts.

Today two streams of monsoon energy appeared to come together over the south end to send a stream of atmospheric moisture to Oman and on to India.
The interconnections between global weather systems is becoming a trend of a fascinating voyage of metereological discovery that started in The #WestSahara in March, moved focus to #Ethiopia and #ArabianStorms in April and has now widened to include Europe and India.
Around lunch I did a wrap up thread about #EuropeanStorms activity caused by Round 1 of the #WestAfricaWaterPlume.
And to see what happened in Round 1 yesterday, this thread is the best place to start.
Dawn breaks on the Middle East and Horn of Africa on 28 April with numerous active storms in play.

#ArabianStorms activity was boosted today by moisture flowing from the #Ethiopian monsoon rains in the Ethiopian Highlands, the watershed of the #Abbay #BlueNile catchment.
Below you see a 10-day GFS forecast of accumulated rain over North Africa.

This animation shows the flows of moisture from this morning across the Red Sea. A process which is called the "Southern Gate" by Saudi weather entusiasts. #ArabianStorms #Abbay #BlueNile #GERD
There was a lot of cloud, #DesertRain #ArabianStorm and #AfricanMonsoon activity in and around the Middle East today.
