Forecast valid for Tuesday 16 July from 00:00 until 23:59 utc


    The cold drop, which during the day has affected and is still affecting the Italian central north, moves quickly towards the south, causing a worsening of the weather even in the south Italy.

    The cyclonic vortex will find areas along its path with still a discrete "fuel" convertible into thunderstorms and heavy rains. In fact, peaks of 1600J / kg are expected, especially between Calabria, eastern Sicily and the Ionian Sea.

    Molise and Puglia

    The thunderstorms will move from north-east (Adriatic sea) towards south-west, in fact these regions will be located on the north-eastern edge of the low-pressure structure, and will be more intense between Molise, Foggiano and the province of Barletta Andria Trani, with local accumulations significant and flooding ( level 2).

    Elsewhere more isolated thunderstorms. Waterspouts will be possible both on the Adriatic and Ionian sides of Puglia thanks to the presence of a strong helicity in the first km of atmosphere.

    Calabria and Campania

    On Campania, thunderstorms will tend to develop in the next few hours, resulting very intense in the central-southern part of the region.

    During the night and during most of the day tomorrow a stormy corridor will be created from the Tyrrhenian towards the Ionian Sea that will cross practically all of Calabria (levels 2-3).

    The most intense thunderstorms will hit the open sea but flooding along the coasts caused by the huge rainfall accumulations cannot be excluded.

    The high helicity values ​​in the first km of atmosphere will favor the formation of waterspouts especially on the Tyrrhenian side.

    Sicily and Basilicata

    These two regions will be found respectively in the south-west and north-east of the storm channel that will hit Calabria.

    Phenomena of moderate intensity will be possible but no inconvenience is expected.

    A little more detail for Sicily, where, once again under a strong jet stream, thunderstorms will be more organized but also more mobile.
