Experts had worried that bad weather would prevent them from gathering samples of gas emissions belching from the roiling volcano. But Mother Nature has cooperated with another clear day.
The mountain has been venting steam accompanied by a near-constant series of small eruptions and volcanic tremors since Friday. The latest burst appearing above the volcano's 8,300 -foot rim was thought to be steam and ash and bigger than Monday’s steam burst.
The National Weather Service has issued an ash fall advisory for the south Washington Cascades.
No matter what occurs in the coming days, most experts continue to maintain it won't match the massive eruption in 1980 that killed 57 people and spread ash over much of the Northwest.
