Weather situation
An Atlantic depression is causing an influx of humid air at altitude from the south-west, while in the lowlands there is a convergence between the north-east which blows on the Friulian plain and the Sirocco which affects the entire Adriatic. During the night and the first part of the morning the convergence remained on the Adriatic, opposite the coasts of Friuli Venezia Giulia and eastern Veneto, triggering showers and thunderstorms moving towards the north-east.
From around 9am the storm gradually moved northwards due to the strengthening of the Sirocco. The rainfall was light to moderate on the coast, abundant to intense on the eastern side, intense in the west.
Forecasts
Thursday 16 May: stationary rain, including thunderstorms, intense or very intense, possible during the night and in the morning, especially on the Pordenone and Udine plains and the Carnic Prealps.
In the next few hours the rain will tend to ease. From mid-afternoon, new intensification of rain, with locally strong showers and thunderstorms, associated with the passage of a front. The rains are expected to gradually stop after midnight.
Friday 17 May: cloudy sky in the mountainous area, variable in the plains, slightly cloudy on the coast. Scattered showers and thunderstorms during the day, more likely between the Pre-Alps and the plain in the afternoon. Rainfall will generally be moderate or locally heavy.
Saturday 18 May: sky generally not very cloudy with more substantial cloud cover towards the mountain area. During the day, scattered and intermittent showers, including thunderstorms, are more likely in the afternoon towards the mountain area. Breezy winds will blow.
