Liverpool England MSHPC Tropical Weather Updates

Before a depression is recognised, it is usually tagged an "INVEST" storm - an area of low pressure with the potential to strengthen into a cyclone. INVESTs are tracked by the MSHPC's satellite bureau in Kompa Ru or the Warning sub-bureau in Cyclonesville with advisories, called Tropical Weather Updates effective 2144 (formerly known as INVEST tracker), on potential systems every 6 hours.

A trial run took place during February 2145 of issuances in Liverpool England's two other official languages, French and German, but both were rejected.

During the off-season, TWUs are only issued when there are active tropical cyclones or a high chance (above 50%) of formation of one. During the season, especially during anti-peaks of the season, the MSHPC may decide to reduce the frequency of TWU issuances to once a week.
