Heavy snow impacted Italy and the Balkans with record snows on both sides of the Adriatic. 100.8” of snow fell in 18 hours. Pescocostanzo, Italy – 21 miles away – picked up 94.5”. The WMO will confirm whether the snowfall did indeed surpass the current 24 hour snowfall record (75.8” at Silver Lake, Colorado set in 1921).

Heavy snow impacted Italy and the Balkans with record snows on both sides of the Adriatic. 100.8” of snow fell in 18 hours. Pescocostanzo, Italy – 21 miles away – picked up 94.5”. The WMO will confirm whether the snowfall did indeed surpass the current 24 hour snowfall record (75.8” at Silver Lake, Colorado set in 1921).
Capracotta record snowfall setup
• Due to the terrain near Capracotta, this village is most susceptible to weather coming from the northeast. As noted in the upper air and surface pressure, wind, temperature, and precipitable water (PWAT) patterns attached, this event provided a near-perfect setup for heavy snow. The center of the low pressure system formed to the southwest of the area; resulting in strong northeast winds over the town. These winds channeled high PWAT air over Capracotta and temperatures continued to drop during the event.
