Portland Fire & Rescue officials announced on Tuesday afternoon that the fire marshal had issued a citywide burn ban due to the fire risk posed by imminent hot weather and a lack of forecasted rain.

The burn ban is expected to last through the summer.

The Portland ban applies to backyard fires, burning yard debris and agricultural burns, the Fire Bureau said in a statement. Open burns normally allowed by permits are also banned until further notice, the Fire Bureau said.

Backyard grilling will still be allowed — although grills, smokers and other backyard cookers should be used at least 10 feet from anything flammable such as bushes or fences, according to the Fire Bureau.

Firefighters recommend putting used charcoal briquettes in a covered metal bin to avoid accidentally starting fires, and added that ashes should be kept wet for several days before being thrown away.

All cigarettes or cigars should be extinguished before being thrown away, Fire Bureau officials said.

Washington County issued a narrower burn ban Monday. Portland and other jurisdictions such as Milwaukie and Eugene have also banned fireworks to mitigate fire risk.
