Dense Fog Blankets Seminole County, Cold Front Brings Sharp Drop
A dense fog advisory affected Central Florida on Dec. 28 and 29, reducing visibility to a quarter mile or less in parts of Seminole County including Sanford. The fog lifted ahead of a strong cold front that forecasters said would bring a sharp temperature drop and a frigid start to the New Year, creating travel hazards and health risks for vulnerable residents.

A dense fog advisory moved through Central Florida on Dec. 28 and 29, producing pockets of very low visibility in Sanford and surrounding communities in Seminole County. Visibility dropped to a quarter mile or less in many areas, prompting meteorologists to advise drivers to allow extra travel time as the fog lingered. Local forecasts said the fog would be stubborn because of light winds and local atmospheric conditions.
The timing compounded concerns for commuters and emergency responders. Reduced visibility increases the likelihood of vehicle collisions and slows ambulance and fire response times. Drivers were urged to use caution on surface streets and highways, to reduce speed, and to expect longer travel times during morning hours when the fog was thickest.
Once the fog moved out, forecasters warned that a strong cold front would push through the region and bring a sharp temperature drop. Temperatures were expected to fall into the 30s across many inland zones, creating a frigid start to the New Year. Colder air and damp conditions can strain cardiovascular and respiratory systems, and they raise the risk of hypothermia for people without reliable heating.
Those impacts fall hardest on residents already facing housing insecurity, limited access to transportation, or chronic health conditions. People experiencing homelessness, elderly adults living alone, and households that cannot afford adequate heating face increased danger when cold snaps follow weather disruptions. Workers who must travel early in the morning may be exposed both to hazardous driving conditions and to frigid temperatures once the cold front arrives.
Local health providers and community organizations are often the first line of support during these episodes. Residents are advised to allow extra time for travel, keep an eye on elderly neighbors and family members, dress in layers, and check that heating systems are functioning safely. Policy discussions could also focus on bolstering warming shelter capacity and emergency transportation plans so that the county can protect its most vulnerable residents when weather extremes arrive.
For now, Seminole County faces a short window of hazardous driving followed by a rapid temperature change, a combination that underscores the need to link weather response with public health preparedness and equity focused support for those at greatest risk.
