Unlike Yellowstone, Alaska's Mt Redoubt volcano really is likely to blow in the next few days. Lots of siesmic activity of late. How much of an explosion is anyone's guess. The towns across the bay could get a few inches of ash. My step-mom lives in Soldotna, but she's not too worried, as she's been through them before. At least one in the chain blows every 5-10 years. Today she stocked up on propane and picked up her BP meds.
