SALT LAKE CITY — It was a year of weather extremes across the state. From dire drought conditions and record heat to extensive flash flooding under torrential rainfall. Utah experienced a variety of weather to make 2021 a memorable year. Here is how we ranked the Top 5 weather related events for 2021.

Due to sporadic snowfall during the winter months of 2021, conditions became ripe for high avalanche danger throughout the winter season. Six deaths were reported for 2021 with four of those fatalities occuring under a single event up in Millcreek Canyon. This is occurred on Febuary 6, 2021. The accident is among the worst in state history.

A huge firefighting force gathered Tuesday to defend Lake Tahoe from the raging wildfire that forced the evacuation of California communities on the south end of the alpine resort and put others across the state line in Nevada on notice to be ready to flee.

For several weeks during July through September, the state experienced poor air quality from the infiltration of smoke due to the wildfires burning in California, Oregon, Washington and Idaho. On August 6, 2021, the air quality was so poor in Salt Lake City that the city was in the top rankings of the worst air quality for that day in the world.

In addition, Salt Lake City tied the record for the hottest temperature ever recorded in SLC on June 15, 2021. The National Weather Service tweeted that it was 107 degrees at Salt Lake City International Airport at 5:43 p.m. The previous recorded hottest temperature for Salt Lake City was 107 degrees in July in 2002 and 1960.

“We just [officially] hit a temperature NEVER before seen in the month of June at Salt Lake City [in] all 147 years of records,” said the NWS earlier in the day, when the temperature hit 106.

Another record was broken when Salt Lake City reached its earliest 100 degree day on June 4, 2021.

Typically, during the summer months, the state of Utah experiences monsoon moisture moving up from the southeast. This provides the development of thunderstorms that can produce significant rainfall and flash flooding across central and southern Utah. The summer of 2021 monsoon season will be one for the history books. Some notable events.
