St Jude blasts through Wanstead

Much comparison has been made of Monday morning’s storm which claimed the lives of four people and 1987. The origin of both storms was down to a combination of a jet streak interacting with a pool of warm air low down. Both storms followed a similar development but clearly 1987 was more optimum. The 1987 storm was slower and further to the west when it developed. This morning’s storm was too much in the jet stream and raced on with less development.

From the forecasts made at the end of last week into the weekend it was about what I expected in terms of intensity – though I thought the peak of the max gusts (47.2mph at 0653) would have been shorter. Rainfall from the event was unremarkable – just 17.5mm which started falling around 9pm on Sunday and stopped around 5am. Totals north of Watford were far greater. This rainfall radar image at 0645 was taken within 10 minutes of the highest gust in Wanstead.

Stations similar to here in Woodford Wells and Laindon all reported maximum gusts of 47-53mph, though with these being sheltered gardens the reality was probably higher – perhaps severe gale force 9 was reached at the storm’s peak here. Andrewsfield, near Braintree, North Essex, recorded 79mph. An animation of the storm’s track clearly shows the path of the sting jet. The Met Office have also released a satellite sequence of events. Of course the storm is no comparison with the Great Storm of October 1987, where a gust of 122 mph was recorded in Gorleston, Norfolk, but this morning’s storm was probably in the top 5 of storms since – and the most potent since the Burns’ Day storm of January 1990.

The tree damage in Wanstead has been worse than I would have expected with a few down on Christchurch Green. My own back yard in Aldersbrook seems to have got off lightly though a small flowering cherry on the corner of Dover Road succumbed. On closure inspection the inside of the trunk was spongy – testament to the fungus that I’d noted had been growing on it recently. Elsewhere, in Wanstead Park, some trees were sadly lost. Friends of Wanstead Park give a brief account of the damage here.

After it left Suffolk the storm raced across the North Sea, still deepening all the while, and caused havoc in Belgium and the Netherlands. Much has been said about the UK media’s obsession with the storm which chiefly affected the south east but Belgian and Dutch news outlets also focussed on the weather. In Brussels people were virtually blown along the street. Falling trees blocked canals in Amsterdam where a cyclist narrowly escaped being hit by a falling tree. There were no reports of deaths across the Channel and some watersports fanatics took full advantage of the wild conditions. The storm, which at one point developed an ‘eye‘, continued its destruction across Germany where this home was almost totally destroyed.
