Two typhoons getting closer and closer to each other. #INFA on the right is sucking the much smaller #Cempaka into its orbit. Sucking up all its outflow and chucking it out east.

The pair of typhoons current winds are fixed by JTWC at 70 and 65 knots at 06Z.
Here are the current warning graphics from the JTWC. ImageImage
#Cempaka is a midget Typhoon (1). Spinning like a top south west of Hong Kong.

Disregarding its size, #Cempaka is directing rain from Hanoi to Taiwan (2). The forecast (3 & previous tweet) shows Cempaka moving west in a loop, but this hasn't started yet. ImageImageImage
#Cempaka above

These views show us what these storms looked like before nightfall.

These two images are trying to capture the relative scale but do not really do so effectively. ImageImage
So what's about to happen. This is the 20 06 GFS PWAT run for 180 hours. Landfall in Japan for the third storm is forecast overnight on the 24th-25th with high winds possibly arriving in time for the Olympics Opening Ceremony on the 23rd.
In this forecast the second phase of super moisture over Japan continues till August 1st.
Then in the final 4 days of the forecast things remain relatively benign. Over Japan.
1. Tokyo forecast rainfall before the storm 24th July

2. Tokyo forecast rainfall after the storm 29th July ImageImage
1. Japan forecast rainfall before storm 24th July (108hrs)

2. Japan forecast rainfall after storm 29th July (240hrs)

3. Japan forecast rainfall after atmospheric moisture has cleared. 1 August (300 hrs)

Once again today we had the peculiar site of a large storm at sunrise over the Arabian Peninsula and Horn of Africa.
And here's a view of the Indian Monsoon this evening India time.
In this image, also from @NASA, we can see the entire Nile. The GERD can be seen in there if you know where to look. With this mass of cloud it was a minor miracle that the dam was partially visible. Image
Today's big pictureshows a view across all of Asia and Africa in which the Indian & East Asian Monsoon are peaking. on the right there are two typhoons, #Cembaka and #INHA which are about to become one after they collide over Taiwan in a couple of days. Image
Today's 10-Day Rainfall forecasts for North Africa from July 20th through July 31st. The #ArabianMonsoonBurst is ongoing and can be seen on the far right of each rainfall forecast. ImageImageImageImage
48-hour rainfall forecasts (today and tomorrow from our standard four models: the European @ECMWF, @NOAA's GFS, Canada's CMC and the Korean KMA models. ImageImageImageImage
Finally for #NorthAfrica we have the long-range 16-day (GFS) and 12-day (KMA) forecasts which continue to show significant #DesertRain in the central Sahara. ImageImage
Here we see a wider angle view of today's cloud movements over the Arabian Peninsula and the Horn of Africa from early this afternoon.
And this corresponding image shows us where the rain was this afternoon. There was a very big storm directly over Khartoum, and a lot of rain over Sudan. For a time there were also clouds covering most of the Aswan Dam. Image
And here's a closeup view of live rainstorms in this storm, which contained - as you can see - a lot of rain today. Image
Today's July 20th 10-day rainfall forecasts for #Ethiopia (+1 12-day from KMA) and the #HornOfAfrica: #Somalia, #Somaliland, east #SouthSudan, south east parts of Sudan, #Djbouti and #Eritrea.

Purple heaviest rain covers #Tigray, & #Abbay (#GERD) & #TekezeAtbara basins. ImageImageImageImage
Before the #MiddleEast forecasts here are a couple of #ArabSotrms observation tweets from today. In this first one I am not entirely sure what I am looking at. But it definitely looks dangerous. Its in #SaudiArabia today.
This one appears to show view from a car which looks a lot like a view from a boat, at Narjan #SaudiArabia.
Check out @ArabStorms for more extreme weather observations.
July 20th 10-Day accumulated rain forecasts for the #MiddleEast from the GFS, CMC, KMA & ACG weather models.

And to conclude the regular elements, a big picture view. North Western Hemisphere zero hour simulation data (i.e. now).

2. PWAT (potential rain + energy)
3. MLSP (Mean Sea Level Pressure)
4. 250Hpa (jet stream winds approx 11-15 kms high) ImageImageImageImage

At this point following the Qatar obscenity Israel is now breaking the internet and the world.

something decisive is needed to break Israel - a peaceful action that will work and show the world that justice still exists and that peace is possible.
A wise friend proposed a brilliant idea. Every nation on earth which is willing and able should send a frigate to the Mediterranean Sea and take a message to Israel that it cannot ignore.
The foundations of the United Nations itself are now crumbling under the weight of the Gaza Obscenity and nations like Britain that seem to have been turned are facing protest and resistance of epic proportions from their citizens.

The center cannot hold.

I’ll be posting videos and news here on Twitter from the flotilla which is about to depart from Majorca for Tunis on the first leg of the journey to Gaza.
More boats are expected to join the flotilla from Europe and North Africa along the way as it moves west across the Mediterranean. @GretaThunberg is making the voyage again and Israel will not be able to contain or stop this flotilla most likely. And definitely not the publicity.
This first video is of a wind squall hitting one of the boats as it departs Barcelona.

Netanyahu has proposed a pathway to end the war in Gaza under pressure primarily from the U.S. UK, France & Germany. Spain and Ireland and several other European nations & the European Commission.

LIVE: PM Netanyahu Holds a Press conference youtube.com/live/1ebXvF9MO…
The @israelipm sounds defeated. Hopefully this is the beginning of the end. The deal being offered to Gaza is far from perfect but it sounds workable in Netanyahus outline.
@IsraeliPM Whether it will be approved by Hamas however is unclear and rather complicated - as it’s unclear who inside Gaza would be in a position to respond to the offer. Many of Hamas’s fighters may prefer to die as martyrs also than to agree to any deal.

Guess who has the most to lose if/when @realDonaldTrump discovers he’s now a lame duck President.

He is now so deep under water both in polling and with his base that it’s very hard to imagine him bouncing back.
I’ll answer my question shortly buts it’s well worth pondering…. In the meantime consider this.

Trump is now a laughing stock. And not only is everyone in America now laughing at him. But he has also been abandoned by his base and his party.
The bonfire of vanity that belongs to Donald Trump is iridescent, a signal to the world that his presidency has ended before it even started.

This is pathetic from @realDonaldTrump he’s lashing out like an angry teenager. Jerome Powell says he’s included a the costs of a building that was completed years ago in his very public attack on the FED Chair.
Trump has completely lost the plot. The single most damaging thing that he could do to undermine confidence in the U.S. dollar (which he publicly claims to want to deflate and there by make all Americans poorer - is to attack the Federal Reserve and the SEC.
@realDonaldTrump Trump is setting fire to the dollar to distract from his Epstein mess what a complete baby.

I attended the Bonn climate talks. They were very disappointing to everyone. The elephant in the room was (of course) the U.S. decision to withdraw from the talks altogether.

open.spotify.com/episode/3YV0SU…
Unfortunately.. perhaps intentionally in advance of the continuation of climate talks regardless of #US_Disintigration the talks were also very sparsely attended particularly by activists and NGOs. The reason for this was @elonmusk destroying @-USAID.
@elonmusk As you can see the USAID Twitter account is now dead - deleted which is an appalling act of vandalism executed by Elon and his tech-bro team of teenagers.
