The National Weather Service has issued a dense fog advisory for Coffee, Dale, and Henry counties in Southeast Alabama, effective until 9 a.m. on Sunday. Drivers should expect visibility to drop to less than half a mile, creating hazardous driving conditions. To ensure safety, the weather service advises motorists to slow down, use low-beam headlights, and maintain a safe distance from other vehicles. In cases of extremely low visibility, drivers should activate their hazard lights and find a safe place to stop, turning off all lights except for the hazard flashers to avoid accidents. Following these guidelines can help mitigate risks associated with foggy driving conditions.
