An upgrade to MDT has been done over Sicily in south Italy given the conductive environment for explosive supercell development during the following hours. An impressive storm cluster is already ongoing just offshore Sicily this morning. Expect threat with heavy convective rain, large hail, severe winds and even tornadoes.

Upgraded northern Algeria into SLGT given the improved environment later this afternoon/evening for large hail, strong winds and heavy rain threat.

Additionally, given the completed frontal passage over the northern Mediterranean, severe treat is diminished and therefore threat levels have been removed.
