A level 2 was issued for the north-west Mediterranean mainly for large hail, excessive precipitation and severe wind gusts.

A level 1 was issued for the western Mediterranean mainly for large hail and excessive precipitation.


A ridge is present across central and northern Europe. Its northern flank will weaken due to a cut-off low moving east across the southern Baltic Sea. The ridge is flanked by a deep quasi-stationary trough centred west of the Bay of Biscay, yielding a strong south-westerly flow over the west Mediterranean. At lower levels, a plume of warm air has spread into western Europe, with an axis from the central west Mediterranean to western France. In the same region, rich low-level moisture is present, whereas dry boundary layer air masses dominate across eastern Europe.
