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.

JUN 13 2145 - 3 AM BULLETIN

ACTIVE TROPICAL CYCLONES...
THE MSHPC IS ISSUING ADVISORIES ON HURRICANE GRIEL... LOCATED EAST
OF THE PAX MERIDIAN... AND ON SUBTROPICAL DEPRESSION FOURTEEN
LOCATED NORTHWEST OF ALTHOS, SPAAMANIAN PLIJOUS.

ELSEWHERE... 
THE MSHPC IS MONITORING HURRICANE ALLANI-DAGON IN ATLANTIAN OCEANIA
CURRENTLY WEST OF THE SMALL ISLAND OF CASARI... AND TROPICAL STORM
CHARLES-LYDIA... LOCATED SOUTHWEST OF CHACOR/EAST-NORTHEAST OF
PEDRIANA.

AN AREA OF LOW PRESSURE NEAR LOX LAND ISLAND BEARS WATCHING...
ALTHOUGH IT IS EXPECTED TO MOVE OVER THE ISLAND LATER TODAY AND NOT
DEVELOP FURTHER IN THE COMING TWO DAYS. NONETHELESS... LOCALLY HEAVY
RAINS ARE TO BE EXPECTED OVER THE LOX LAND ISLAND AND SURROUNDING SEAS
AS THE LOW MOVES ONSHORE.

A NON-TROPICAL AREA OF LOW PRESSURE VERY NEAR NORTHEASTERN DASHAKE WAS
THE SUBJECT OF A RECENT SHIP REPORT OF 45 KNOT WINDS. SEA-SURFACE
TEMPERATURES ARE NEAR 27 DEGREES CELSIUS... SO SLOW DEVELOPMENT OF
THIS SYSTEM IS POSSIBLE. THE FACT THAT HURRICANE GRIEL WILL BE NEARBY
IN ABOUT A DAY SIGNIFICANTLY COMPLICATES FORECASTS DUE TO POSSIBLE
FUJIWHARA EFFECT TAKING PLACE. NONETHELESS... HIGH WINDS TO 50 KNOTS
SHOULD BE EXPECTED OFF THE SEAS OF NORTHEASTERN DASHAKE.

OTHERWISE... NO TROPICAL CYCLONE FORMATION IN THE HEARTLAND IS EXPECTED
THROUGH JUNE 20.

NEXT TWU AT 9 AM HPT.
