More hot dry weather is expected to challenge fire fighters this week and even for much of September.Jeree Mills is with the Northwest Fire Coordination Center and she says experts in that center are closely watching the short and long term forecasts. "It’s so bad that the concern, we came in Saturday and put out an extreme weather alert. It’s just rapidly changing fire weather. Takes off like that." Temperatures are expected to rise into the triple digits in some parts of the state, with low humidity and high winds forecasted. The biggest problem with the wind is not even the speed at which it blows, but the unpredictable nature. As for the latest on the Shadow Lake Fire 15 miles from Sisters, it’s still estimated at 4600 acres with no containment yet. The huge fire complex burning near Warm Springs has grown slightly to 107,000 acres. And it's a pivotal day on the Dollar Lake Fire burning near Mt. Hood. Its size is now 7 square miles, and it's 20% contained. That fire is expected to send a lot of smoke into nearby Sandy.
