Porphyry Fire Update
September 25, 2020

The Porphyry Fire is still estimated at 14,486 acres, due to more accurate mapping, as fire progression was slowed thanks to rain and lower temperatures. Friday and Saturday will bring cooler temperatures, higher relative humidity and a chance of rain showers across the Payette National Forest. No season ending event is forecasted for the Payette National Forest area. A season ending event is when wide spread precipitation of a quarter inch is received for three consecutive day.  Temperatures will begin to climb back up Sunday and that will allow fuels to dry back out. Fire spread and activity may increase as the fire area dries out but overall fire activity will be low due to time of season, cooler temperatures and length of daylight. 

Although rain is expected over most of the Payette National Forest, fire season is still present, and all precautions should still be followed.  

The Porphyry Fire will continue to be monitored by air and ground as needed. Crews continue structure protection on 4 bridges and one structure along with mitigating some hazard trees around the Big Creek and Edwardsburg area.

An area closure remains in effect for the Porphyry Fire. Agency administrators urge South Fork boaters to move quickly through the section impacted by the fire, and for hunters to remain away from the closure area. There are no current threats to structures, but Golden Hand Mine is in the current path of the fire. The closure area will be re-evaluated after the weekend.
This will be the last report until Monday, September 28, 2020

Current Weather

Weather Concerns

A cold front moving through the area this morning will bring in showers by mid-morning and continue through mid-afternoon. Gusty west winds on the ridgetops behind the front, then clearing with diminishing winds overnight. On Friday, another upper-level wave moving through the flow will increase winds again, and showers are likely around the area Friday afternoon into early Saturday. Drier and warmer weather, with light winds, expected from later Saturday through at least the middle of next week.
