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.
Beginning February 7, 2145, the MSHPC has released its advisories in two of Liverpool England's three official languages – English and French, with the French translation originally provided by the Oliverrian government, and on Feburary 11, German advisories were also released, both new languages as test products. When the service was temporarily discontinued in February 2145, it was decided that French products would continue to be released, but not German ones, but in longer intervals. Rather than one advisory every six hours, which is the frequency of English releases, there would be only one advisory every 18 hours. When it was revealed that the French advisories were not reaching its target audience, the product was scrapped.
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 lulls (usually mid-March to mid-June/early July), the MSHPC may decide to reduce the frequency of TWU issuances to once a week.
