VA SIGNAL IN SATELLITE IMAGES REMAINS STRONG SO CONFIDENCE IS HIGH
IN INITIAL AND SHORT TERM FORECAST OF VA. AIRCRAFT REPORT OF SO2 AT
FL470 OVER CENTRAL PORTION OF SIGMET AREA BUT WE BELIEVE VA DOES
NOT EXTEND TO THAT LEVEL. AT LEAST A PORTION OF THIS VA WILL LIKELY
PERSIST FOR AT LEAST ANOTHER 12 HOURS.
