Editor’s note: A fire that burned 35 acres near Phoenix on Saturday night was sparked by someone mowing in dry grass, officials said.

“An investigation determined the fire was caused by mowing a fuel break during hot, dry conditions — a well-intentioned activity that nonetheless emphasizes the need for fire safety awareness as wildfire season begins,” the Medford Fire Department said in a statement Monday.

“The fire began in a rural area within Medford Rural Fire District 2 and quickly spread through dry fuels, prompting Level 2 and Level 1 evacuation notices for three Phoenix zones: Zones 12, 14, and 16. Fortunately, crews were able to halt forward progress of the fire at 35.3 acres, with no injuries or property damage reported,” the statement said.
