Fairbanks, Alaska (AP) - A wildfire that has burned in Delta Junction since April has expanded due to high winds.
The Oregon Lakes Fire in the Delta Junction area expanded along its western perimeter Saturday night.
The Bureau of Land Management's Alaska Fire Service says the fire has not moved northward, but smoke from the southwest area mixed with sand blown up from the Delta River has formed clouds visible from Delta Junction.
Officials say the fire was listed Sunday at 27 square miles and crews are working to protect structures in surrounding communities.
Transportation and observation flights were temporarily canceled due to high winds and poor visibility.
The cause of the fire is believed to be man-made, but is still under investigation.
