The Burns' Day Storm (also known as Cyclone Daria) was an extremely violent windstorm that took place on 25–26 January 1990 over North-Western Europe. It is one of the strongest European windstorms on record and caused many fatalities in the UK and Europe. This storm has received different names, as there was no official list of such events in Europe at the time.[6] Starting on Burns Day, the birthday of the Scottish poet Robert Burns, it caused widespread damage and hurricane-force winds over a wide area.
The storm began as a cold front over the Northern Atlantic Ocean on 23 January. By 24 January, it had a minimum central pressure of 992mbar and began to undergo explosive cyclogenesis, which was sometimes referred to as a weather bomb.[7] It made landfall on the morning of January 25 over Ireland. It then tracked over to Ayrshire in Scotland. The lowest pressure of 949mbar was estimated near Edinburgh around 16:00. After hitting the United Kingdom, the storm tracked rapidly east towards Denmark causing major damage and a further 30 deaths in the Netherlands and Belgium.[1]
The strongest sustained winds recorded were between 70and, comparable to a weak Category 1 hurricane or Hurricane-force 12 on the Beaufort Scale. Strong gusts of up to 104mph were reported, which caused the most extensive damage. The Great Storm of 1987 contained considerably higher wind speeds across every parameter but affected a smaller area of the UK; both highest recorded sustained wind speeds of 86 mph and highest gust of 135 mph, for example. Sustained periods of high gust speeds were also far higher in 1987. However, during the 1987 storm, many anemometers stopped recording because of power outages, breakages by the excess wind speeds and measurement maxima being exceeded. By 1990, the meteorological community had newer devices that remained independent of external power and could measure higher wind speeds. The general opinion is that wind speeds measured during the Burns' Day Storm provide an accurate picture, but there is a tendency to downplay windspeeds from the 1987 storm because of the patchy data available. In the 1987 storm, it was the counties of Sussex, Surrey, Kent and Essex (i.e. the SE of England) which were worst hit and suffered the most damage. A Met Office forecaster the previous day, Michael Fish, notoriously said he had assured a lady enquirer that "there was not going to be a 'hurricane'".
The Burns' Day Storm of 1990 has been given as an example of when the Met Office "got the prediction right".[8] The model forecast hinged on observations from two ships in the Atlantic near the developing storm the day before it reached the UK.[9]
During the day of the storm, the Royal Netherlands Meteorological Institute (KNMI) increased warnings to force 11 and eventually to hurricane force 12. It conducted research that showed that most of the general public could not understand the severity of the warnings. The storm has led to more awareness and understanding of storminess among the public by the KNMI, which started a teletext page and the introduction of special warnings for extreme weather events in reaction to these findings.[10]
Casualties were much higher than those of the Great Storm of 1987 because the storm hit during the daytime. There were 47 deaths in the UK, most caused by collapsing buildings or falling debris.[11] In one case in Sussex, a class of children was evacuated just minutes before their school building collapsed. The actor Gorden Kaye was also injured during the storm when a plank of an advertising board was blown through his car's windscreen.[12] The storm caused extensive damage, with approximately 3 million trees downed, power disrupted to over 500,000 homes and severe flooding in England and West Germany. The storm cost insurers in the UK £3.37 billion, the UK's most expensive weather event to insurers.[13]
