The Lombardy Region confirms for today Sunday August 30, the “orange” warning for hydrogeological risk and “yellow” in case of severe storms.
These warnings are often cautious, but as yesterday’s case in Val Veddasca demonstrated, flooding and storms don’t need much to create traffic difficulties.
In the next few hours, the transit of the cold front is expected, linked to the vast depression responsible for the episode of strong instability in the region with subsequent weakening of the unstable flow from the southwest between the afternoon and the night of today. In fact, from 6:00 p.m. hydrogeological risk orange, along with that of severe thunderstorms 18.00 for the areas of the lakes and Pre-Alps of Varese.
As for the hydraulic node of Milan, on the other hand, storms and strong winds will be alerted from 13-14.00 today. The hydraulic hazard (“yellow”) starts from 6:00 p.m.
Tomorrow is Monday 31 august, the region will be found within a vast but softer, cooler cavity at high altitude, which will again determine a slight instability that Tuesday September 1st it will move east with a temporal rotation of the northern high-altitude currents. Therefore, for today August 30, the phase of gradual attenuation of the phenomena is confirmed from the afternoon that, however, in an isolated or dispersed way can be present until the night. At night, phenomena generally absent or unlikely isolated rains.
«The region is affected by a very humid and unstable flow from the southwest that generates, on several occasions, showers and storms even of strong intensity throughout the region (medium and large hail, strong gusts of wind). From the start of the event until today, August 30, the accumulated precipitation is quite uneven in Lombardy, higher in the Alps and Pre-Alps where (from the regional rainfall network) maximums of 266 mm are registered in the province of Varese, 265 mm in the province of Como; It also exceeded 200 mm in the province of Sondrio. In the flat strip, a maximum of 88 mm in the province of Brescia. In the Alps and Pre-Alps, in the last 24 hours they have fallen locally to 100-140 mm ”, reads the document released by the Region.
