Round two of #WestAfricaWaterPlume vs #EuropeClimate is about begin. As dawn breaks round one continues to play out over Poland.

Meanwhile in the Middle East the 13th consecutive day of #ArabianStorms ovrer the Arabian Peninsula has begun.

#ClimateChange

If you are new to this very rapidly unfolding, and rather epic story a good place to get up to speed is this #WestAfricaWaterPlume vs #EuropeClimate thread from yesterday.

As the sun went down last night plume driven storms were underway across Spain, France, Italy, Switzerland, Austria Germany and Czechia.

Over night a lot of people in central Europe had a noisy night as these storms moved north and consolidated. Here we see the storms crossing the alps, French, Swiss and Austrian from 7-10pm CET.

This shows the consolidated storms progression north through to 1.15am CET this morning.

.. by 5.15am the storm was over Warsaw.

... by the time the sun came up a couple of hours ago it was covering more than half of Poland.

Over 13 hours the storm traveled 1300kms growing, and developing into a powerful low pressure system on way,

As of 9am this morning the cloud circulation diameter is now 1000 kms.

The storm is continuing to move northwards rapidly as it rotates relatively slowly.

Importantly, none of what is happening is in the weather forecasts. Weather models have not been able to keep up with the pace of change, nor (I suspect) the complexity of the interactions.
