Advisory on Potential Closures:
The prevailing northeast tradewinds generally blow fumes from the volcano away from visitor areas. However, during times of weak winds or winds from the south (the opposite direction), volcanic fumes may impact visitor areas, prompting the park to close. Please be flexible and alert.
What should you do when you notice hazy/smoky/smog-like conditions (VOG)?:
Park rangers monitor air quality and will advise visitors when the situation prompts a closure. When a closure is ordered, please leave the area in an orderly manner with everyone's safety in mind. See: Visitor Alert - SO2 Advisory
