VOLCANIC SMOG = VOG

The island of Anatahan one in a chain of islands north of Saipan is a live volcano. It periodically erupts sometimes spewing steam and ash 50,000 feet into the air. This is then carried in any direction the wind chooses to blow. Trade winds normally blow from ENE to WSW sparing the island of Saipan most of the time. Occasionally the winds will shift and leave the island shrouded in VOG. This is not too serious but there are advisories for older people, children and asthmatic patients. The sunny day the sun didn't shine......... Shown is Garapan on Saipan during a vog day. GED
