\u00c0 la mi-mars 2026, de fortes pr\u00e9cipitations combin\u00e9es \u00e0 une hausse rapide des temp\u00e9ratures ont entra\u00een\u00e9 une activit\u00e9 avalancheuse exceptionnellement \u00e9lev\u00e9e dans les Columbia Mountains, \u00e0 l\u2019int\u00e9rieur de la Colombie-Britannique \u2013 le plus grand cycle naturel d\u2019avalanches de la saison.<\/p>

Depuis 2018, les pr\u00e9visionnistes et techniciens de Parks Canada utilisent les syst\u00e8mes de d\u00e9tection d\u2019avalanches IDA\u00ae<\/a> et LARA\u00ae<\/a> de Wyssen Avalanche Control comme \u00e9l\u00e9ment central de leur travail quotidien dans le parc national des Glaciers. Au cours de ce cycle intense de cinq jours, le r\u00e9seau de d\u00e9tection d\u2019avalanches (ADN)<\/a> a enregistr\u00e9 \u00e0 lui seul plus de 850 \u00e9v\u00e9nements d\u2019avalanche dans le parc national des Glaciers \u2013 soit plus de 25 % de toutes les d\u00e9tections enregistr\u00e9es cet hiver.
Cet hiver, nous avons enregistr\u00e9 jusqu\u2019\u00e0 pr\u00e9sent un total de 3096 d\u00e9tections d\u2019avalanches<\/strong>. Ce cycle en repr\u00e9sentait 27 %<\/strong>. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Les pr\u00e9visionnistes se sont appuy\u00e9s sur ce flux continu de donn\u00e9es en temps r\u00e9el via la plateforme web WAC.3\u00ae<\/a>, ainsi que sur les donn\u00e9es int\u00e9gr\u00e9es des stations m\u00e9t\u00e9orologiques, afin de suivre l\u2019\u00e9volution temporelle de l\u2019activit\u00e9 avalancheuse, d\u2019identifier les tendances et de soutenir des d\u00e9cisions op\u00e9rationnelles cl\u00e9s \u2013 y compris le d\u00e9clenchement \u00e0 distance d\u2019avalanches \u00e0 l\u2019aide des m\u00e2ts de d\u00e9clenchement Wyssen, qui ont \u00e9t\u00e9 activ\u00e9s \u00e0 trois reprises durant ce cycle dans le cadre de mesures coordonn\u00e9es de gestion du risque.<\/p>

Ces donn\u00e9es aident les autorit\u00e9s \u00e0 mieux comprendre l\u2019ampleur de l\u2019activit\u00e9 avalancheuse tout en minimisant l\u2019exposition directe aux dangers d\u2019avalanche.<\/p>
