Large plumes of smoke from a fire in Brooklyn are disrupting subway service on nearby lines.

The fire broke out Tuesday morning in Williamsburg on Hewes Street less than a block away from the elevated subway tracks that run above Broadway.

The fire started at a one-story commercial building that appears to be a lumber storage facility.

Firefighters are still battling the flames and heavy smoke. No injuries have been reported at this time, according to FDNY.

Service on the J and M lines could be disrupted. Commuters should expect delays and try alternative routes to avoid the area.
