On day 2 of official #GERD filling we have glimpse through the clouds and what looks like a nearly full GERD lake in a recent photograph taken after the spillways were commissioned this year.
This morning's rainfall update thread is attached here.
The thread also looks at a major #DesertRain event to the west of the Horn, over Sudan, Chad and Niger where August/September like rains appear to have come early.
Here's an update from this afternoon with satellite estimated rainfall over the last 24 hours showing 14-35mms of rain over the #Abbay basin.
Here's the @NASA Modis satellite image from this morning (which contained the glimpse of the #GERD in the OP). To the west of the Horn there is a very large and growing area of rainfall which is about to get stronger.
Today's big picture contains all the usual elements. Black Sea low. West European storms and of course the Indian and West African Monsoons and the latest daily #ArabianStorms.
Today's 10-Day Rainfall forecasts for North Africa from July 7th through July 18th.
All models are now forecasting widespread rainfall over #Yemen towards the end of the forecast period. Note also the rainfall in the Sahel. The CMC model may be a over playing this a bit though.
Here's a live satellite detected precipitation map showing current storms across the region.
48-hour rainfall forecasts (today and tomorrow from the same four models: the Euro @ECMWF, U.S. @NOAA's GFS, Canada's CMC and the Korean KMA models.
And finally for #NorthAfrica we have the long-range 16-day (GFS) and 12-day (KMA) forecasts - which remain remarkably well aligned.
Here we see a nearly live image of today's intense storms over the #Abbay.
This zoomed out perspective shows the winds bringing the rain from the storms over India on the right hand side and their consequences, the strengthening monsoon over East and Central Africa and #ArabianStorms
Two of the three models are now forecasting rain for Somalia.
48 Hour forecasts (today and tomorrow) from the same three models. Over this period significant rainfall is not yet forecast for #Somaliland, but it does appear to be coming soon. #Tigray and #Eritrea continue to have rain though, modest amounts in the former.
Today's #ArabianStorms are interesting in their configuration, the rain band that forms over Yemen extending north west into Saudi Arabia in particular.
As sunset approached the #ArabianStorms in the middle of the Arabian Peninsula grew stronger. The second image is from half an hour after the first one. #DesertRain
The 10-Day accumulated rain forecasts for the #MiddleEast from the GFS, CMC, KMA & ACG weather models are showing increasingly more #DesertRain in #Yemen and #Oman.
The rainfall forecasts are long-range July 7th rainfall forecasts. The16-day GFS & GEFS models, the 12 day KMA and the 15 day EPS (Euro ensemble) model forecasts for the #MiddleEast.
THREAD: Some thoughts on October 7th and the importance of their being global transparency over what we know about what really happened on that terrible day.
1/ This (see screenshots in the first few posts in this thread) is one of the most important pieces of conflict related journalism published in recent years.
It relates to the orders given to soldiers on October 7th to fire on any vehicle seeking to return to the Gaza Strip to prevent the taking of hostages and was published on July 7th, 10 months later in Haaretz.
2/ As @IsraeliPM Benjamin Netanyahu prepares to address congress it is vital that the public in the US, Israel and globally is fully aware of what exactly happened on October 7th in Gaza.
3/ The account in this story published by Haaretz is at this time still behind a paywall and it has therefore not been read by the very large number of people who ought to have done so. I have not seen very many reports containing the detail of this report elsewhere though I presume there are many.
OK so clearly #HurricaneBeryl is not the same as #HurricaneHarvey. But there are some striking similarities in terms of what has made it so much more persistent than either forecast or as modeled.
This thread is going to look at this issue a bit more deeply.
- The overall cloud mass of the #HurricaneBeryl thunderstorm complex proved much more resilient than expected once it came over land. Why?
- Also Like #Harvey Beryl did slow down after making landfall and continued to spin over land. Why?
- I think the answer to both questions relates to the very warm waters of the Gulf of Mexico. Like Harvey back in 2017, Beryl has been fueled by a constant stream of warm wet atmospheric flows of energy off of the Gulf of Mexico.
- This is obvious in part simply from observing the astonishing expansion of the cloud field after #Beryl made landfall early this morning.
A clue to understanding this can be found in looking at the the astonishing growth progression of #HurricaneBeryl's cloud field over landafter Beryl strengthened and formed itself into a Hurricane in the period after making landfall south of Houston.
Over the course of the rest of the morning you can see in these images how much the wind field expanded.
Like Harvey #Beryl also grew and strengthened itself by feeding off of the gulf of mexico, specifically the area between the Texas coastline and what looks like the outer boundary of the convection field which expanded extremely strongly to the north.
The only source for all this additional atmospheric moisture can be the oceanic convection which took place in what is a fairly clearly bounded 136,000 km2 area of ocean which as you can see in this animation is very closely bound to the rest of the circulation.
This is a much much larger area than the area of active rainfall which settled over the city and metropolis of Houston for the morning and which is finally starting to move off to the north now.
This version of the graphic shows the comparative sizes of the area of water which is responsible for the astonitising growth of post landfall #HurricaneBeryl - and the area of the storm that remained over the ocean and which is almost certainly responsible for both why this storm was so persistent and why it (like Harvey) slowed down after coming ashore.
#HurricaneBerylis not expected to give up lightly as it moves onshore and turns north eastward over Texas and then heads north east across the great planes towards the great lakes.
Typically we expect hurricanes to weaken rapidly over land - especially wind wise. But #Berylis not forecast to behave as normal - probably because like Harvey, its tail over the Gulf is keeping it fueled. - the currently forecast pattern from Fox News's exclusive model shown in these images was present in some of the simulations of Beryl after it crossed the Yucutan a couple of days ago.
To my mind questions ought to be asked about the accuracy of the forecasting for this storm, as - like the last super destructive Texas Hurricane, Harvey in 2017 [] Beryl is proving to be a LOT more destructive in its impacts than initially forecast.en.wikipedia.org/wiki/Hurricane…
The final image in this sequence of screenshots of Fox Weather Graphics is worth drawing attention to as it shows how much broader the impacts of this hurricane are expected to be as it moves across the great planes roughly speaking heading up the Mississippi river, and continuing to dump potential flooding rain as it goes.
This image shows the forecast expected severe weather threat from the remnants of #HurricaneBeryl in Arkansas and Missouri up as far as Saint Louis.
ALERT: High Target News Environment in play - numerous consequential news events with global implications.
1. British elections - (Thursday July 4th-Friday July 5th): Delivering an unprecedented landslide win to the left's @UKLabour Party + strong showings for the Liberals and Greens . The UK Chancellor @RachelReevesMP will shortly set out her economic policy in a speech.
2. French elections (Sunday July 7th) deliver a remarkable 2nd big win for the left in politics in France - dashing the hopes of Marine le Pen's hard right wing "Rassemblement National" of first parliamentary victory
3. Overnight (7th-8th July): an unprecedented huge Hurricane , #Hurricane Beryl - makes landfall in Houston as a Category 1 Hurricane, its main threat to the epicenter of the global fossil fuel industry will be flooding. It is still night in Houston at present.

This report also addresses the widening rift between Israeli PM Netanyahu and the U.S. Government. True to form Netanyahu is showing no sign of backing down. But this tweet showing former Defence Minister Yoav Gallant leaving on a U.S. flight for the U.S. speaks volumes in this very intense moment.
