Italy and Malta

Small upper/mid-level disturbances associated with the long-wave trough will provide lift to very unstable air masses. Storms will fire up even before noon and slow storm motions show a high threat for flash floods. Moreover, weak wind field and very unstable air masses over the sea, along with very warm SSTs increase the threat for waterspouts near the coasts of Italy and Malta, as well as in the east coasts of Corsica and the Adriatic Sea later on Wed 04/09.

A broad, subtropic ridge filled with very warm to hot air covers most of Europe. It is flanked by small cut-off lows near Ireland and Portugal and by a long-wave trough over Russia. The main frontal zone is deflected to the far north and runs across the Norwegian Sea and Scandinavia.
