Anytime a tropical cyclone (TC) is in the WFO Guam Area of Responsibility, WFO Guam issues increasing
information regarding the TC(s). At a minimum, Public Advisories are issued every 6 hours, but as TC
watches/warnings are issued for islands (lead times of 48hr/24hr of the arrival of damaging winds (39 mph / 34
kt)), Public Advisories increase to every 3 hours, as well as the 6-hourly issuance of the Local Statements. More
information about our special TC text products is below, as well as a 12-hour clock cycle of our TC operational
schedule.
