Flames engulfed a marina in Seattle’s University District, burning dozens of boats early Wednesday.

The two-alarm fire in the 700 block of Northeast Northlake Way on Portage Bay was reported shortly after 2 a.m.

According to the Seattle Fire Department, as many as 30 boats at a dry rack storage facility were burning when firefighters arrived and the fire had spread to an adjacent warehouse.

Firefighters confirmed no one was inside the warehouse.

Smoke from the fire could be seen from miles away and caused parts of the Seattle area to have air quality in the moderate to unhealthy for sensitive groups range. At one point there were 100 firefighters at the scene as well as a fireboat.
