US: Authorities working to contain wildfire in Mariposa County, Calif., as of early July 5

Crews are working to contain a wildfire burning in Mariposa County, California, as of early July 5. The French Fire broke out early evening July 4 near the community of Mariposa. The fire has burned around 320 hectares (790 acres) and is zero percent contained. The fire has broken out amid an ongoing heatwave in the region and warm, dry, and breezy conditions have aided the fire's growth; further wildfire growth will likely occur in the coming hours and days.

The fire is primarily threatening eastern and northern parts of Mariposa and as of early July 5 authorities have issued evacuation orders and warnings for several roads in the area; full details and maps on the locations of evacuation orders can be found here. Officials have established an emergency shelter at New Life Christian Church on Cole Road in Mariposa.

Depending on the progression of the wildfire, the status of nearby roads could change over the coming hours and days. Authorities may close additional routes within the wildfire complex and evacuate more communities depending on fire activity and the needs of response operators. The return of residents will probably disrupt traffic flows after authorities lift evacuation orders. Power outages are likely in affected areas. Low visibility from smoke and possible ashfall could contribute to traffic delays and congestion in the region.
