Tropical Weather Updates are 12-hourly outlook bulletins issued during cyclone season by the Liverpool England Meteorological Service Hurricane Prediction Centre that summarises tropical weather activity in The Heartland, and gives a short-term forecast of possible development of tropical cyclones. They are sometimes issued outside-of-season, at a rate of one every 24 hours, when there is (rare) tropical activity.
