Signs of autumn are appearing
Autumn has set in, bringing colder weather, especially at night. Drivers should expect ice and slippery patches on roads overnight and into the morning. Road users are encouraged to check weather and traffic updates on trafficinfo.is , be prepared for changing conditions, and drive with caution.
In the coming days, the Icelandic Road and Coastal Administration warns of night frost and hazardous driving conditions on mountain roads on Friday, Saturday, and Sunday nights, extending into the following mornings. Ice or icy patches are likely in many areas, particularly in North, Northwest, and Northeast Iceland, where nighttime temperatures are expected to fall below freezing. On Sunday, however, milder weather is forecast, which may ease road conditions as the day progresses.
Sleet is also expected on Friday and Saturday, especially in the north and northeast. Sleet may reduce visibility and make driving difficult, while slush could form on mountain roads on Friday night and Saturday morning. Because such conditions can develop suddenly, drivers should anticipate slower travel and remain alert to changing road conditions.
The Icelandic Road and Coastal Administration urges all road users to closely monitor weather and road reports before setting out, particularly when traveling over mountain passes. Drivers are advised to take necessary precautions, such as ensuring winter tires are in good condition, and to exercise extra caution on exposed routes and heathlands, where weather and road conditions may change rapidly.
