An image of thunderstorm activity in the Ethiopian #Abbay #BlueNile basin this afternoon, also showing significant rains South #Yemen and over most of #Somalia.

Todays, 27th April, accumulated rain forecasts for the #MiddleEast & #HornOfAfrica follow in the thread below.
#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
This process strengthened over the day, on a day which has seen an astonishing level of Storm Activity across the Kingdom of #SaudiArabia and has seen significant rainfall on the @HolyKaaba in Mecca / Makkah.

This made me cry …. Tears streaming down my face. This is so very sad.

#Gazaunderattack
#GazaUnderFire
If @realDonaldTrump chooses to join Netanyahu’s genocidal campaign if he is not obeyed …. he WILL find himself indicted in the international criminal court in The Hague.

And he will then have to make a decision on whether he is willing to remain in the U.S.
@realDonaldTrump Should he proceed as he has intimated that he should now be pursued by protestors everywhere he goes.

The best outcome of this would be if it turned into a Dunkirk result for the injured and wounded of Gaza to be taken to Europe for medical treatment.
There is a lot of concern about evacuations of civilians from Gaza in the flotilla as anyone leaving may not be able to return any time soon. /2
But the moral hazard here is palpable. There are thousands of injured and starving mostly women and children. And we saw the young babies dying in the hospitals in the early stages of this war. /3

More and more naval vessels from Europe and the Middle East are being deployed to protect the Global Samir Flotilla as it moves slowly but surely towards Gaza where it intends to deliver aid and global attention. /1
Attacks from drones on the flotilla have resumed and Israel is presumably responsible for this. It is because of this that naval vessels from Europe are now joining the flotilla to protect their citizens rights of travel in international waters. /2
The escalation appears fairly slow at present and the flotilla is still within Greek waters at present /3

The #Samud #GazaFlotilla is currently sailing across the Ionian Sea towards the island archipelago south east of Athens in the Western Mediterranean. Conditions appear good for this leg that departed from Sicily after leaving Tunisia. The Flotilla set off from Barcelona. Image
2/ this current leg is 860 kms roughly and lead boats in the 51 vessel flotilla are currently approaching south western Greece. You can follow the flotillas progress here >> flotilla-orpin.vercel.appImage

3/ After two drone attacks on flotilla boats in Tunisia the flotilla sailed first to Sicily where it was joined by several more boats. And this map shows the path of the flotilla so far. The numbers in the dots indicate more vessels joining #GazaFlotilla Image
