I'm an air traffic controller at HCF Center (the airspace that has this aviation red warning). I wish I was working there right now to see this firsthand, but I'm currently in Oklahoma City at the FAA center. If anyone has any questions, I'll do my best to answer them.<p>The summary says the ash cloud is drifting southwest which would put it on the south end of the Big Island. Almost no one flies that way so it shouldn't have a big impact on aviation traffic.
