voornamelijk voor overvloedige regenval. Gisteren was er een level 1 en toen gebeurde er op de buien in zuid België na niks.
Ben benieuwd vandaag. Zie hieronder de voorspelling van estofex. Estofex.org
A level 1 and level 2 are issued for the Netherlands, W and S Germany, Austria, Hungary and parts of the Balkans mainly for excessive convective precipitation and to a lesser degree for large hail.
(3) Netherlands, W and S Germany, Austria, Hungary, Slovenia and Croatia:
Slightly cooler and drier air advances westward, and the convergence zone at its leading edge creates a focus for convective initiation. Downwind of the mid-level ridge axis, a slow storm motion from NW to SE (i.e., parallel to the boundary) enhances the risk of flash floods. A belt of 10-15 m/s upper-tropospheric flow might enhance deep-layer shear just enough to allow marginally large hail or plentiful small hail. In general, the wind and hail risk is kept low by the moist airmass with rather skinny CAPE profiles, though.
Two areas with the strongest lift (either synoptic or orographic) and the expected highest storm coverage around the border of Belgium, the Netherlands and Germany and from the Austrian Alps southeastward are upgraded to a level 2. Otherwise, the less clear position of the convergence zone and the possibility of morning convection with ensuing limited daytime heating enhance the uncertainties, and a level 1 seems more appropriate.
niet goed... te westelijk...
