A big day for #WestAfricaMonsoon observation.

A full plume event is becoming obvious in central & eastern Europe + Russia. We also have thunderstorms over the Red Sea, and a low circulation heading towards a collision with water vapour over Israel.

Today's forecasts follow.
Visually speaking this is the most extraordinary looking satellite observation of the day.

Now into its sixth day the #EastAfricaWaterPlume has been generating lots of rain over the Red Sea, both last night and today, & right now just off the coast of Jeddah. @Arab_Storms
Here we see a wider view while it is not that obvious in this view, the stream of water vapour heading up the Western Sahara coast is running fast and hot. Later I will post an initial post tracking its impact in Europe. But for now its worth looking closer at North Africa.

With Cyclone #Yaas soaking up all the moisture east of the #MiddleEast and #HornOfAfrica it was a relatively calm day. Albeit not without another intense set of storms along the Red Sea Coast in the Jinzan mountains.

Today's rainfall forecasts follow.
The days began relatively quiet on the #WestAfricanMonsoon front thanks to Cyclone #Yaas. This image shows a strip from the Libyan Coast across the Sahara down to the Congo.
And it remained fairly quiet over the great forests of equatorial Africa today. But further West over the Ivory Coast and the West Sahara the #WestAfricaWaterPlume continued to pump water vapour across the Sahara into Europe.

Cyclone #Yaas is just 2 days away from landfall on the North Eastern Indian Coast in the Odisha and once onshore is forecast pass over the ancient city of Jaipur.


Today's #MiddleEast #Sahara and #HornOfAfrica forecasts follow.
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.

This morning's rainfall forecast is actually last nights (I am in the process of moving - a bit stretched. There is a lot going on.

Here we see the ongoing impacts of a #WestAfricaWaterPlume coming into the Middle East and 2 large storms, one over Syria and one over Medina
Here are last night's 10-day rainfall forecasts for North Africa which are nothing short of astonishing with respect especially to what is expected in #Algeria and #Mauritania. The largest forecast #DesertRain event to date.
This animation is from the is morning and shows the current status of both #WestAfricanMonsoon events. The Plume directed at the #MiddleEast is continuing and the one in the west Sahara is strengthening.

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.

The Horn of Africa this morning @NASA worldview, got a great view and more pictures will be included in today's rainfall forecast thread for #Ethiopia #HoA and the #MiddleEast.

Today's forecasts follow.
Here's the first. A view mostly of #Sudan, capturing both the #WhiteNile and #BlueNile as well as part of the Nile below Sudan on its way to Egypt. On the right hand side Lake Tana can be seen through the clouds.

If you look very carefully you may be able to see #GERD.
This view which captures the area below that in the previous image has borders on it to make it easier to see where the abundant green in the firsy image in this thread is located. The rains of the past few weeks appear to be doing God's work in the region.

<< Baltic Faceoff >>

These two storms now look fairly evenly matched.

The storm on the left (over the UK) is powered by the North Atlantic, while the one on the right over Russia is powered by the #WestAfricanMonsoon

& bottom left over the Med. a spoiler is arriving.
I didn't see this earlier but the marked triangular bit in the top left of this image is the reason the UK Storm didn't manage to push the Russian Storm off the mat.

That's a jet of airborn water that has somehow managed to find its way both into & out of the Arctic.
The Nordic interloper is there at the beginning of the sequence before the sun sets.

These four images show the sequence of events.

There is something glorious about the images that @zoom_earth captures. I especially like the large symmetrical and fairly stationary area of cloud in the North Atlantic in this image.

Today's May 1sy Forecasts for #Ethiopia and #MiddleEast rainfall follow.
The main action today was in Europe where the strengthening #WestAfricaMonsoon #WMA has today had a spectacular impact on European Weather.

A detailed thread covering those events can be found here.
Today's North African long range (12 day) rain forecast is taken from the Korean KMA model as it looks to be a lot closer to what we are seeing in the skies today.
