Flight Operations received notice on March 17, 2003, from the National Weather Service, that the Montserrat volcano had erupted, sending particulate and ash into the atmosphere. Volcanic ash was transported into populated areas as east to west upper and lower atmospheric wind patterns shifted north by northwest. All aircraft enroute to San Juan, Puerto Rico, St. Croix, St. Thomas, Antigua, Santo Domingo and St. Maarten were immediately contacted by dispatch to try to divert aircraft away from the adverse effects of this meteorological condition. Flight operations were ended for almost 6 hours in San Juan and its surrounding area until a volcanic ash pilot report and Notice to Airmen was rescinded. Major volcanic activity occurred again at Montserrat on July 12, 2003. The dome of the volcano collapsed, spewing particulate and ash into the atmosphere. An Airbus aircraft inbound to San Juan, Puerto Rico came upon an unforeseen cloud of ash at about 6000 feet. The encounter ended up causing damage to the aircraft's forward flight deck windows and engine fan blades.
