Een tubawolk welke later over zou gaan in een wind/waterhoos.

De water/windhoos die voort kwam uit de bovenstaande tubawolk.
Ik zag deze fenomenen vanaf de straddle carrier op de Maasvlakte
The level 3 region in W Romania and SW Ukraine was downgraded due to high CIN revealed by the 12Z soundings which is likely to keep the storm coverage at a low level. Significant severe weather like very large hail and severe winds above F1 intensity is still possible but the expected coverage is not as high as expected from the previous model runs.
The level 1 over the Netherlands and NW Germany was removed due to stabilization of the boundary layer and therefore less convective activity and a marginal tornado risk. Some slight adaption was made to the lightning areas.
