The situation around Arco

A rainy week around Trento: rain fell on several of the last seven days. Leading for the Arco area over the last 14 days is Apple Weather. Looking at rain only, first place in the provincial capital goes to iLMeteo.it. Wind was the defining feature of the week, with strong gusts almost every day. Yesterday's report card reshuffled the order: the week's No. 3 finished No. 2. Nearby municipalities (Ronzo-Chienis, Drena) have the same service in first place. A curious detail: yesterday the service ranked last overall was among the two most accurate on the provincial capital's report card. Rain makes up three quarters of the score and temperature one quarter: in a week this wet, rain is what makes the difference.
