During November, temperatures were slightly below average across large portions of Italy\u2019s mountain areas, creating favorable conditions for snow, particularly toward the end of the month. This enabled an initial growth of the snowpack, which, however, was not supported by adequate precipitation availability, especially in Northwestern Italy, the core region for the Po basin\u2019s snow water resources.  <\/p>\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-7387b849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img data-dominant-color=\"cce2e2\" data-has-transparency=\"false\" style=\"--dominant-color: #cce2e2;\" fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"1009\" src=\"https:\/\/www.cimafoundation.org\/wp-content\/uploads\/2025\/12\/T1-1024x1009.avif\" alt=\"Temperature anomaly - CIMA Research Foundation - Snow report for snow water resources\" class=\"wp-image-16024 not-transparent\" title=\"\" srcset=\"https:\/\/www.cimafoundation.org\/wp-content\/uploads\/2025\/12\/T1-1024x1009.avif 1024w, https:\/\/www.cimafoundation.org\/wp-content\/uploads\/2025\/12\/T1-300x296.avif 300w, https:\/\/www.cimafoundation.org\/wp-content\/uploads\/2025\/12\/T1-768x757.avif 768w, https:\/\/www.cimafoundation.org\/wp-content\/uploads\/2025\/12\/T1-1536x1514.avif 1536w, https:\/\/www.cimafoundation.org\/wp-content\/uploads\/2025\/12\/T1-2048x2018.avif 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Fig. 2.

Across many parts of the country, particularly in Northwestern Italy and the central Apennines, November recorded precipitation totals well below average, with negative anomalies reaching up to -60% compared to climatological values<g id=\"gid_0\"><g id=\"gid_1\">2<\/g><\/g>. In the absence of significant inputs, the potential offered by low temperatures has so far not translated into a sustained and substantial accumulation.  <\/p>\n\n<p class=\"wp-block-paragraph\">This dynamic is clearly visible when examining the evolution of the main Alpine river basins. In the Po basin, the increase observed in November was followed by a phase of substantial stagnation during the first two weeks of December. Such a slowdown at the beginning of the season represents a critical factor, as it introduces a delay that, if not recovered in the following months, may affect the overall winter water balance. As of 13 December, the deficit in the Po basin stood at -48%. New snowfall occurred last Tuesday, particularly in the Cuneo area, where fresh snow accumulations locally exceeded 1 m; in January, it will be possible to assess their contribution and, above all, whether this snow has been able to persist at higher elevations.    <\/p>\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<figure class=\"wp-block-embed is-type-wp-embed is-provider-flourish wp-block-embed-flourish\"><div class=\"wp-block-embed__wrapper\">\n<iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" title=\"Interactive or visual content\" src=\"https:\/\/flo.uri.sh\/visualisation\/26717701\/embed#?secret=EpVoqnOWXI\" data-secret=\"EpVoqnOWXI\" frameborder=\"0\" scrolling=\"no\" height=\"575\" width=\"700\"><\/iframe>\n<\/div><figcaption class=\"wp-element-caption\">Fig. 4.

At higher elevations, above 2500 m, conditions are relatively better, although deficits on the order of -25% to -30% persist.
