A 2nd theme of today's weather observations is the awesome power of atmospheric water transfer.
Here we can see how a stream of water originating in the Central African Republic is fueling storms in Saudi Arabia & India.

Today's forecasts follow.

The latest GFS North Africa 10-Day Rain forecast.

Here we see atmospheric water leaving north across the Sahara for Europe this afternoon.

And here we see the booster engine for the flow of atmospheric water to India, in the highlands of Ethiopia and the deserts of the Sudan.

It seems likely that the rains will reach Khartoum soon.

May 2nd, 10-day accumulated rain forecasts, for Ethiopia, from the ECMWF, GFS and KMA models.

And a couple of fresh @Arab_Storms eyewitness videos of #ArabianStorms the first from near Makkah.

And the second @Arab_Storms #ArabianStorms tweet contains an eyewitness video showing the formation of part of the storm in the attached animation. [I suspect Zoom.Earth from @zoom_earth incorporates some game design AI.]
