Firefighters expect to fully contain the deadly Wine Country wildfires this week, just as a final blow to the burn areas is anticipated from above — in the form of rain. The most vicious blaze to explode across Sonoma and Napa counties three weeks ago, the 36,807-acre Tubbs Fire, was 98 percent contained Sunday, nearing the 100 percent mark when crews are confident they’ve entirely surrounded the burn with fire breaks. The blaze has killed 22 people and leveled 5,300 structures, most in Santa Rosa.
