Narrative:
While enroute [to] mmto approximately 15-20 min before top of descent; received following SIGMET for volcanic ash from volcano. SIGMET area depicted on flight explorer was within 20 NM of mmto airport. It was still dark down in mmto; so no way to visually assess actual presence of ash. Flight not tankered due to payload; so out of abundance of caution; coordinated with crew and service recovery to divert flight to filed alternate of mmgl. Shortly after making the turn to mmgl; mmgl forecast amended to ¼ SM for our time of arrival so subsequently amended to add further alternate of MMMY. At time of [reporting]; mmgl weather holding and aircraft X in descent for landing at mmgl. Shift note written and duty officer as well as manager on duty notified.
