Alta ski season snowfall record!

The Alta ski season (October 1st-April 30th) snowfall record of 748" from the 1981-1982 season has been destroyed and replace by 903" from the 2022-2023 season! This record is from the Alta Collins study plot at 9662' in elevation.

*According to the Western Region Climate Center the maximum winter (October 1st- September 30th) snowfall record for the town of Alta is 846.8" during the 1982-1983 season, we need to wait until September 30th to see if that record will be broken as well. 

Utah Snow Water Equivalent is 214% of Normal

Here is today's Utah statewide snow water equivalent (30.0" which is a record) chart and basin map which might be the peak for the year.

Alta snow depth record!

 On April 5th 2023 Alta hit its all time snow depth record of 248"! The previous record was 236" on May 19th 1983.

Utah Snow Water Equivalent is 196% of Normal.

 

Looking at the above chart is shows an average of 28.0" of snow water equivalent from all of the SNOTEL stations around Utah which is a record!

Alta snowfall record?

With all of the snowfall record talk this year at Alta I wanted to clarify things a little due to some confusion. The all time Alta ski resort record for snowfall has been smashed (800"+ and counting) this year with one month to go. The Alta ski resort snowfall season includes all snowfall between October 1st and April 30th at the Collins study plot which is at 9662' in elevation.

The all time season (includes all months) snowfall record for the town of Alta is 846.8" from the 1982-83 season. For this record the snowfall data was taken from a study plot at or near the current Alta guard study plot which is at 8799' in elevation.

This is just an educated guess but if someone had been around to measure snowfall at the Alta Collins study plot for the entire water year in 1982-83 and 1983-84 one or both could have topped 900".

Possible new Utah low pressure record!

 Looking at the below Vernal airport observations from today it looks like the 28.94" Hg (980 mb) could be a new Utah State record for the lowest pressure ever recorded!

Peter Sinks

Peter Sinks in Utah (near Logan summit) has hit -62F this morning! Link to the current temperature at http://weather.gov/wrh/timeseries?site=PSINK The on-minute average low occurred between the 15 minutes observations listed. This is the lowest temperature recorded in Utah since -62F at Middle Sinks (very close to Peter Sinks) on January 30th 2002.

Peter Sinks is a natural sink hole at 8,164 feet in elevation, it is about 1/2 mile in diameter. Cold air sinks at night and pools into this natural sink hole making it much colder than nearby areas, also no one lives there. On February 1st 1985 Peter Sinks was -69.3F which is the record low for Utah. More information about Peter Sinks at https://climate.usu.edu/PeterSinks/index.php
