Central Indiana woke up to thick, low-visibility fog that prompted multiple school districts to adjust their schedules Monday, with many students beginning the day on a delayed start.
The National Weather Service in Indianapolis issued a Dense Fog Advisory for portions of central Indiana, which remained in effect through the early morning hours. Under the advisory, visibility dropped significantly in many areas often to just a few hundred feet making travel more hazardous for morning commuters and school buses alike.
The fog was most concentrated before sunrise, when calm winds and cool overnight temperatures allowed moisture near the ground to condense into a dense blanket of fog. In some spots, conditions were reported to be so thick that drivers could barely see ahead, raising concerns about safe travel to school and work.
In response to these conditions, many school districts across central Indiana announced delayed start times. Social media traffic and school announcements indicated that a large number of districts implemented two-hour delays for the start of classes so that visibility and travel conditions could improve before buses began rolling and students arrived on campus.
For districts reporting delays, the extra time was intended to give fog a chance to dissipate and reduce risk on roads that were already more difficult to navigate early in the morning. While not all schools were affected, the disruptions were widespread enough to prompt parents and guardians to check local district communications before heading out.
Officials emphasized that the decision to delay school start times was driven by concerns about student safety and transportation conditions. Dense fog can impede school bus routes and increase the likelihood of traffic incidents, especially during peak commute periods.
Parents and drivers were also reminded to use caution and keep headlights on low beam, as high beams can reflect off fog droplets and further reduce visibility.
Typically, dense fog conditions like those seen Monday morning begin to lift after sunrise as temperatures rise and the sun burns off the moisture near the ground. By mid-morning, visibility was expected to improve significantly, allowing schools to resume regular schedules and normal operations.
