Warmer and drier weather mixed with extremely steep terrain has helped fuel the Nohomin Creek Fire near Lytton.

The BC Wildfire Service says the out-of-control blaze now covers more than 22-square kilometres.

“Fire activity has significantly increased on the northern portion of the western flank, located north of the Stein River,” it said, in an update late on Thursday night. “Planned ignitions may be utilized as early as [today] to remove fuel between the fire and preidentified natural control lines.

“The containment lines the crews have been building on the south, east, and north flanks continue to hold up well against gusting afternoon winds.”

The Wildfire Service also says lower humidity will cause fuel to dry out, creating potentially volatile conditions during peak burning times.

In all, it says 1,500 feet of sprinklers and hoselay has been installed along the Stein Valley walking path to add moisture into the valley bottom ahead of the anticipated hot and dry afternoon conditions.

“A coordinated approach in the response and protection of the Stein Valley Nlaka’pamux Heritage Park will continue to be a priority for Lytton First Nation, BC Parks and the BC Wildfire Service,” the statement added.

“A representative from Lytton First Nation that specializes in archeological site and cultural values is working with structure protection specialists and BCWS crews to identify cultural values and provide guidance and recommendations on the best options for protection of those values.”

The Wildfire Service says there are currently over 175 personnel assigned to this fire, with support from eleven helicopters and multiple water tenders.

The Nohomin Creek Fire, which started on June 14, has destroyed at least six properties and forced more than 100 people from their homes on the west side of the Fraser River.
