The National Weather Service has issued a dense fog advisory until 9 a.m. for 12 counties in southern Kansas, including the Wichita metropolitan area.
Visibility was generally a quarter-mile or less, with some spots down to near zero, meteorologists said. A Sedgwick County dispatcher said only one accident had been reported by 7:20 a.m., but that changed within minutes as the morning commute grew in intensity.
Recent rains and little to no wind set the stage for the fog to develop. Fog could again be an issue late tonight and early Saturday, forecasters say.
