The dense fog advisory poses significant risks to drivers in central, north central, and northeast Wisconsin. Visibility reductions to a quarter-mile or less can lead to dangerous driving conditions, increasing the likelihood of accidents. Patchy drizzle may exacerbate the situation by making roads slick, further heightening the risk for motorists. Those traveling early Monday morning should be particularly cautious, as the fog is expected to persist until 9 a.m. The advisory underscores the importance of vigilance and preparedness for those in the affected areas.
