Dense Fog Advisory Affects Morning Commute
A dense fog advisory is currently in effect for Upstate South Carolina and is expected to expire at 11 a.m. today, Wednesday, January 7, 2026. The advisory warns of significantly reduced visibility across the region, creating hazardous conditions for morning commuters. Drivers should anticipate areas where visibility could drop to a quarter-mile or even less, making travel particularly challenging.
Recurring Fog Conditions Prompt Ongoing Caution
This period of dense fog marks a continuation of similar atmospheric conditions experienced over the past few days in Upstate South Carolina. Authorities had previously issued a dense fog advisory for the region, including Oconee, which was in effect until 11 a.m. on Monday, January 5, 2026. Prior to that, another dense fog advisory was active for Upstate SC on Sunday morning, January 4, 2026, also resulting in limited visibility for travelers. The frequent occurrence of these foggy conditions emphasizes the importance of consistent vigilance from drivers and residents in the affected areas.
Understanding Dense Fog Hazards and Safe Driving Practices
Dense fog presents a considerable threat to road safety due to its ability to severely limit a driver’s perception of the road ahead, other vehicles, pedestrians, and potential hazards. This drastic reduction in visibility can lead to delayed reaction times, difficulty in accurately judging distances, and an increased risk of collisions, including multi-vehicle incidents.
When driving in foggy conditions, the National Weather Service and other safety organizations recommend a series of precautions to mitigate risks. Drivers should immediately reduce their speed to ensure they can stop within the limited distance they can see ahead. It is crucial to use low-beam headlights, as high-beam lights reflect off the water droplets in the fog, creating glare that can further worsen visibility. If a vehicle is equipped with fog lights, these should also be activated.
Maintaining a much greater following distance between vehicles is also essential to allow ample time to react to sudden stops or changes in traffic patterns. Motorists should avoid sudden braking or steering maneuvers, which can be particularly dangerous in low-visibility conditions. To help stay in the proper lane, drivers are advised to follow the lines on the road with their eyes. Special attention should be paid at intersections, highway exits, and railroad crossings where visibility challenges are compounded.
In situations where fog becomes so dense that visibility is near zero, the safest course of action is to pull off the road to a safe location, such as a parking lot or driveway. If no such area is available, pull as far off the side of the road as possible. Once stopped, drivers should turn on their hazard lights and turn off all other lights, including taillights, to prevent other drivers from mistakenly running into a stationary vehicle. Waiting for conditions to improve is often the most prudent decision in extremely dense fog.
