(Aloha, OR)  --  Tualatin Valley Fire and Rescue currently has a burn ban in place for the areas it services.  That includes various counties including Aloha, Beaverton, Durham, King City and Newberg.  The ban outlaws all but small outdoor fires, which are those just three feet in diameter or less.  Crews say they expect other local state agencies to tighten burning restrictions soon too as warmer and dryer weather is on the way.
