Here's a message from Tim Olk: Frankfort, IL – Box Alarm House Fire – Heavy Fog and No Hydrants, Plus a Box Alarm Fire in the Next Town Over – A 2.5-story frame home was involved in a heavy fire on the first floor. Firefighters had to conduct defensive operations due to limited water supply and challenging conditions caused by thick fog. The fire spread quickly, making it difficult for crews to gain control early on.
