Utah is on alert for a potentially stunning celestial event. A significant geomagnetic storm may lead to the visibility of the northern lights, or aurora borealis, across the state. However, weather conditions could affect viewing opportunities.
Geomagnetic Storm Watch Issued
The Space Weather Prediction Center has announced a G4 (severe) geomagnetic storm watch. This warning was issued on Tuesday due to a series of coronal mass ejections from the sun. These solar events are expected to impact Earth between Tuesday and Thursday, with early Wednesday anticipated as the peak period for the storm.
Rare Occurrence
G4 watches are considered “very rare,” according to the agency. This is the first such alert in months and only the fourth issued since the solar cycle began in 2019. The heightened activity from the sun may cause disruptions to critical infrastructure across the country.
Visibility of the Northern Lights
Stronger solar flares increase the likelihood of witnessing the northern lights. These beautiful displays happen when solar particles collide with the Earth’s atmosphere, creating vibrant colors in the night sky. The increased geomagnetic activity over the past two years has allowed Utah residents to experience the northern lights multiple times, most notably on May 11, 2024.

As of Tuesday afternoon, experts from the University of Alaska Fairbanks predict the storm could peak between 8 p.m. and 11 p.m. Utahns may be able to see the lights statewide during this timeframe. Matthew Cappucci, a meteorologist from MyRadar and NPR, suggests that if the storm reaches G4 intensity, the lights could even be visible as far south as Oklahoma or northern Georgia.
Weather Conditions and Cloud Cover
Despite the excitement, clouds may hinder visibility. Rainy weather from a storm system off the California coast is expected to arrive in Utah Tuesday night into Wednesday morning. Major cloud cover is likely between 9 p.m. and midnight.
According to KSL meteorologist Matt Johnson, clouds could obscure the northern lights across much of Utah on Wednesday night. However, eastern regions of the state may have better visibility options.
Conclusion
Utah is bracing for a potential celestial spectacle as the geomagnetic storm unfolds. Residents should keep an eye on the sky, as opportunity exists for a rare sighting of the northern lights this week, contingent on weather conditions.
