A level 1 and level 2 were issued for SE England, BeNeLux, N and E France, Switzerland, central and S Germany, the Czech Republic and Austria mainly for severe wind gusts and to a lesser extent for tornadoes.

A level 1 and level 2 were issued for NE Italy, the N Adriatic Sea, Slovenia, the N parts of Croatia, Bosnia-Hercegovina and Serbia, and the W parts of Hungary and Slovakia mainly for severe wind gusts and tornadoes, and to a lesser extent for excessive precipitation.

A level 1 was issued from Scotland into NW Germany mainly for severe wind gusts.


A strong zonal flow is present across Europe. A first cyclone tracks eastward into Russia and brings wintry conditions into Scandinavia and northeastern Europe in its wake. Behind a transient and progressive ridge over central Europe, the next cyclone (ex-hurricane "Gonzalo") moves from Scotland towards Denmark, and a new trough ejects from the British Isles into central Europe.
Quiescent conditions prevail over southwestern and southern Europe, apart from quickly increasing Mistral and Tramontana winds over the western Mediterranean Sea at the rear flank of the amplifying central European trough.
