The National Weather Service is warning of an increased fire danger on Friday.

The alert is for much of northwest Ohio, including Findlay and Hancock County.

Counties a little more to the west, including Putnam County, are under a Red Flag Warning for critical fire conditions.

Forecasters say minimum relative humidity values will fall to 15 to 25 percent Friday afternoon.

The low relative humidity values in addition to breezy southwest winds of 15 to 20 mph with gusts to 30 mph will result in an increased fire danger on Friday afternoon.

The threat is greatest in rural areas where harvest activities are occurring.

Any fires that start could spread out of control.

Outdoor burning is not recommended.
