A level 1 was issued for a belt from the Netherlands towards the Balkans mainly for excessive precipitation and to a lesser extent for large hail.

A level 1 was issued for a belt from S Italy towards the Turkish West coast mainly for large hail and waterspouts.

A level 1 was issued for Central France for severe wind gusts and tornadoes.


The main frontal zone is distinctly split into two branches, the Southern one running across the Mediterranean region and the Northern one across Scandinavia. In-between, rather low geopotential and weak gradients cover most of Europe. Two upper-level lows are moving from the Channel towards S France and from Central Italy to the Aegean Sea, creating an elongated stretch of unsettled and cool conditions. Warmer but equally moist air is present over Central Europe and over the Balkans, where a broad minimum of surface pressure has formed.
Weak anticyclonic influence creates dry and brighter conditions over Northeastern Europe. However, in the far North a cyclone moves from Finland into adjacent Russia, and a surge of polar air will enter most of Scandinavia in its wake.
