Ethiopia forecast rainfall update: 21st April 2021
GFS, KMA and ECMWF Model forecasts - all 10 days.
NOTE: There is a significant increase in expected rain over the 10 day period compared to forecasts from earlier in April.
Here is an animation from this afternoon of rain cloud formation over the Blue Nile Basin today. It is picking up speed.
And here is an animation of an explosive burst of convection south of Mogidishu in Somalia. In 5 hours the storm had grown to be larger than the island of Ireland.
The little rainy season is gaining strength over the Horn of Africa. This animation shows storm activity this afternoon and evening in the #BlueNile#Abbay river basin in #Ethiopia, where the waters flowing into the #Gerd originate.

Europe may now have a very wet final 2 weeks of Spring, rather than a very cold one. Question is, how wet? Catastrophically so... or just wet wet. threadreaderapp.com/thread/1384500…
The question posed by the burst of high energy West Africa Monsoon air on Friday which broke the @ECMWF yesterday and surprised the @NOAA GFS today is not related to the actual weather itself.
For 8000 years from 12000 BC to 3000 BC this was normal & Europe didn’t drown. /2
The question posed by this relates to climate change.
The transit of moisture across the Sahara may be a rare event, or it may be the new normal with a stronger WMA. Time will tell. And the weather models will learn.
