Detroit residents are experiencing unusually dense fog conditions, prompting comparisons to the climate of London, England. The persistent fog, which began developing several days ago, has significantly reduced visibility, impacting travel and daily life across Metro Detroit.
The phenomenon is attributed to a combination of meteorological factors, according to Kim Adams, a meteorologist with WDIV Local 4. “Fog is basically a cloud that sits on the ground,” Adams explained. “In winter, we spot a few common ways it forms. Radiation fog happens on clear, calm nights when the ground cools and chills the air, leading to saturation. Advection fog occurs when mild, humid air passes over colder surfaces like snow or ice.”
Current conditions are exacerbated by Detroit’s proximity to the Great Lakes – the Detroit River, Lake St. Clair and Lake Erie. Light winds are drawing moisture from these bodies of water into the lower atmosphere, increasing humidity and contributing to fog formation. Recent damp and mild weather, including rain, drizzle, and melting snow, has further saturated the ground, adding to the atmospheric moisture. Visibility has dropped to a quarter mile or less in some areas, triggering Dense Fog Advisories when conditions worsen.
The fog can also create hazardous conditions due to the potential for freezing fog. When temperatures fall below freezing, water droplets can freeze upon contact with surfaces like roads, trees, and power lines, creating a thin coating of ice. This poses a risk to drivers and pedestrians alike.
Even as the current conditions are unusual, the fog is expected to dissipate as drier air moves into the region, winds pick up, or sunshine warms the ground. A shift in weather patterns is anticipated to bring clearer skies and colder temperatures over the weekend, offering some relief from the prolonged fog.
London Fog Chimney Sweeps, a local company established in 1979, has been serving Metro Detroit for decades, offering chimney and fireplace services. The company, which has been featured on local media including WDIV Channel 4’s “Ruth to the Rescue,” emphasizes the importance of chimney safety and maintenance, particularly during periods of damp weather. They serve communities including Livonia, Canton, and Bloomfield Hills.
A separate event, “Fog 17,” is scheduled to take place at TBA in Detroit, according to Resident Advisor, a platform for electronic music events. Details regarding the event are limited.
