Why doesn't Slopes' snowfall match the resort's report?

Slopes and the resort are measuring different days. Most resorts, and most weather apps, measure new snow first thing in the morning, usually around 6am. That means their total for a day includes the snow that falls the night after you ride. Slopes splits the day at 4pm local time instead, when most resorts close.

Why 4pm?

Snow that falls after the lifts close is snow you'll ride the next day. Splitting the day at 4pm means each day's total includes the snow that fell overnight and the snow that keeps falling while you ride. A 6am report misses anything that falls after it's taken.

That's why Slopes splits each day's snow into two parts:

• Overnight: from 4pm the day before until 6am. This is the fresh snow that's waiting for you first thing.
• While you ride: from 6am until 4pm

For example, if 4 inches falls overnight and another 2 inches falls between 9am and 2pm, a resort's 6am report says 4 inches. Slopes shows 4 inches overnight and 2 inches while you ride, 6 inches for the day.

What you'll see in the app

• After 4pm at the resort, any new snow counts toward tomorrow.
• Slopes always shows both Today and Tomorrow, so you can check either one.
• The time is always the resort's local time, not yours.

So it's normal for the resort's report and Slopes to show different numbers, even when both are right.
