Snow day forecast for Thunder Mountain Middle School

Thunder Mountain Middle School is a middle school in Juneau, Alaska, part of Juneau Borough School District. The forecast above uses the school's own coordinates, so it reflects conditions at this campus rather than an average across the wider area.

Closure decisions for Thunder Mountain Middle School are almost always made at the district level. If Juneau Borough School District closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Juneau Borough School District forecast).

Town area — what that means for closures

Town districts sit between urban and rural conditions: main routes are usually cleared early, but outlying pickups can stay hazardous well past sunrise.

Alaska averages about 75 inches of snow per year. Alaskan schools rarely close for snow alone — extreme wind chill and ice storms are the primary triggers.

How this prediction is calculated

We score the live forecast at this location against the factors that drive closure calls: snowfall total and intensity, when the heaviest accumulation lands relative to the morning commute, ice and freezing rain, wind chill, and how confident the forecast models are. You get a probability for a full closure, a two-hour delay, and an early dismissal.

This is an independent forecast, not an official announcement. Confirm any closure with Juneau Borough School District before acting on it.
