Includes a video But what if it happened day? The same weather scenario but with the benefit of modern forecasting: though not technically a hurricane, red severe weather warnings out because of the real potential for strong, damaging winds. This big improvement is thanks to much higher resolution computer modelling for weather forecasting.






My memories

Where was I on the night of the Great Storm, Thursday October 15th – Friday October 16th 1987?
 I was in my very very late teens, studying in Southampton, about a fortnight into my second year, living in halls. The autumn term had started unsettled, in weather and in mind. October began with a fine sunny day but then the weather became more changeable. My science degree course was stimulating and I was doing well, yet I felt anxious, apprehensive and down for much of the time. Even more so the following year, my final year. My outlook was invariably bleak, At the time, I thought this was typical student angst. I now know, I was living,completely unknowingly with autoimmune liver disease (AIH) – seeArtyTransplantee blog. Although I didn’t have any obvious physical symptoms, it was affecting my mood for the worse. Relief came partly through praised for doing well in course assignments, but mainy getting out during the weekends and university holidays either solo, with my parents, or as part of the university rambling and hillwalking group
.
Earlier on that Thursday night, I was at the P&B block (now relocated onto the main campus. I think it was a social evening for the freshers, like the one I’d been to at the beginning of my first year. Bored and not making much impression on the first years, I left early and headed back to Halls. It was raining and the wind was getting up, but that was nothing compared to what was to come during the early hours. I was completely unaware of the weather forecast.

I didn’t sleep well on the best of nights (the liver thing probably). That one, though, I woke up in the early hours. I’m wasn’t sure if it was still raining, but the big thing was the roaring wind, like nothing I’d encountered before. The gusts came and went in quick succession, threatening to blow in the aluminium framed window of my fourth floor room. I looked out of the window to the courtyard; leaves and litter swirling in a vortex as the wind howled round it. The lamppost swayed. I think the lights stayed on most of the time, but did go off at least once. I don’t remember seeing or hearing any other people, outside or inside. I think I was awake all through the early hours, listening to the wind outside and cogitating on the highs and lows of the summer.

The wind began dying down just before dawn. With the power still on in my hall, I put the radio on, the Radio 4 Today Programme and news “The whole of the southeast has been devastated…trees down; many roads blocked; vehicles and buildings hit by falling trees; power cuts…walls of roofs ripped off buildings”… The local news said “Don’t ring in to say there’s a tree down, we are being swamped with calls”. No mention of river flooding anywhere, it was all the wind, gusting to over 80 miles per hour in places, including London.

Over breakfast, expressions of shock among my flatmates, otherwise business as usual. I headed off (on foot) to my lectures, on time as if nothing had happened. I don’t remember any trees down (though my walk was through a built-up area) or any other obstructions. I don’t think I felt much more of it until the evening. The only thing was, the trains were still disrupted when I headed off out with the walking group on the Saturday morning. I nearly got left behind on the train at Southampton as no one sure there what was going on; Parkstone misheard by the railway staff as Pokesdown. But we got to Poole Harbour. I think then, we took the Purbeck Ferry to Studland and walked up onto the Purbeck chalk ridge. From there, a view over Poole Harbour, in bright sunshine.

It didn’t occur to me to phone or even write home to tell my parents and grandparents that I was OK, or check up on them. True, phoning home from uni’ was hassly back then: long queues for the one and only payphone in a block of upwards of fifty people; no mobiles / smartphones, texts or email; but the post was fine and I could have written home. I regularly did, with whacky letters, and got them back, eg the Pink Paper Brigade in my first year, to which my father responded to with drawings of our pet golden Labrador unravelling metres of pink loo roll, au Andrex. But not on this occasion. Nothing until a couple of postcards: one from Mum saying “What a wind!”; and one from Grandad asking if I was OK “your mother being particularly anxious”.

Sheltered from the open sea and some way up the Itchen estuary from Southampton Water and the Solent, this part of Southampton had escaped the worst effects of the storm. It was worst over Surrey, Sussex and Kent. Though I saw the pictures on the TV news and in the papers, I didn’t appreciate the wider extent and impacts until I headed out further afield. In early November I went to Arundel – warnings of loose roof tiles; bare patches in the hillside near the Black Rabbit, where trees had come down; and a big branch of the arbutus tree by the bridge had been torn off. Distinctive for its red bark, it subsequently came down in a storm in autumn 2000; then replaced with a cutting from a similar tree at Kew. It was closer to home in woody Surrey where it was particularly noticeable: the local woods and (Farnham Park) where we walked the dog and played as younger children. Large swathes laid bare of trees at Puttenham Common (Cutmill) and Leith Hill, both along the very wooded ridge of Lower Greensand. “Spring will be a bit blighted this year”, my Dad said one day early in 1988 at Puttenham Common. One of the worst affected areas on the South Downs was Chanctonbury Ring, to the north of Worthing. During a half-term South Downs Way YHA based ramble in the early 1980s, this had been a thick rounded clump of trees, similar to Norfolk Clump, above and east of Arundel now. Blowing in from the SW, the Great Storm brought down most of the trees on the south and western sides, and in the centre. Though the trees have since been replanted and regrown, the evidence was still there when we last looked in 2014; the trees on the north and east sides being much taller.

On the night of the storm, my Dad slept through it all, but not Mum. During the build-up at bedtime, she’d had the feeling that it would “not be a normal wind”. Like me, she lay awake for much of the night, hearing the wind roaring. I don’t think the big tree close to the front of the house and garage dcame down, but the apple tree in the back garden did. I think they were able to replant it, but anchored to the ground for a while. On the Friday evening, they mentioned a difficult journey to and from Guildford along the A31, which runs along the Hogs Back, the narrow chalk ridge at the western end of the North Downs.

In the aftermath of the meteorologal storm, a media storm. Blowing in after the notorious Michael Fish BBC TV forecast before the storm hit on the Thursday, the Met. Office came under fire for failing to forecast it. I was annoyed at lack of understanding here about the complexity of weather forecasting. As the Met.Office say in their recent new release and factfile, though, this prompted an overhaul of how they present weather forecasts / weather warnings to the media and the public. Thirty years on, thanks to big improvements in the resolution of weather modelling by super-computers, forecasts are much more accurate. Compare and contrast Michael Fish’s forecast with the mock forecast, under the same conditions in the video attached to attached to their news release (11th October 2017). There seemed to be a phase during the 1990s through to about the early 2000s, when a storm would be forecast, and probably talked up by the media, only for a What was all that about? moment afterwards when it turned out to be not that bad really. Whenever they’ve said storm / heatwave / snow and ice are coming during the 2010s,  they’ve meant it.

Debate, too – was it wasn’t a hurricane? Technically it wasn’t: the sea surface temperatures in the north Atlantic are too cold for that. Hurricanes are tropical storms. It was a common-or-garden low pressure system (like Ex-Ophelia, Storm Desmond etc). Nonetheless, it was a deep one – the central pressure was just 951 millibars according to the Met. Office. Deeper than Ex-Ophelia (963mb, though not as deep as the Christmas 2013 storm which was around 936mb). Deep enough to generate very damaging winds, certainly hurricane force.

“The worst storms in living memory!” screamed a letter from someone near the River Swale at Richmond, Yorkshire; read out on Radio 4 a few days afterwards. “Why does everyone take the south to be the centre of the universe?”. She went on to remind them of the March 1968 storm which had struck Glasgow. I was too young to remember that one, but by all accounts that was bad. There was also flooding in Carlisle. The flow on the Eden peaked at around 1200 cumecs (NRFA: http://nrfa.ceh.ac.uk/data/station/info/76007), prompting the building of flood defences which held until overtopped by an even bigger flood in January 2005. Nevertheless, I think anyone living and knowing SE England well would agree on the severity of the storm in terms of the tree toll and damage to property. Certainly for me, it’s had a lasting, even if delayed, emotional impact.

In the years after 1987, I was nervous when high winds forecast or heard, eg during a storm in late October 2000 when we had a power cut. We were living in NE Hampshire then. Before our move there, we rented a flat in a multi-storey block in Petersfield. Though the weather while we were there was generally quiet, any wind there was whistled round the courtyard, unsettling me. All the more so with our aluminium window frames reminiscent of  my student hall.

A few days after the 1987 storm, Monday 19th October, though totally unconnected, came the“Black Monday” stockmarket crash.
The stockmarket soon recovered, but not long after the Great Storm, my  suspicions that something was up with the weather and climate (global warming) mounted. Though extreme weather is nothing new (Storms in 1703; cold and flood in winter 1947 etc) but my perception is that it has been getting more common, worldwide. Before the Great Storm, there was major flooding in SE England in mid-September 1968 and the notoriously long hot summer and drought of 1976. Less than three years later was the Burns’ Day Storm, January 1990. As the strong winds hit during the daytime, when more people were out and about, more people were injured and the Europe-wide death toll was about 98 (Wikipedia).
Subsequent notable wind / rain events include: autumn 2000 – there was the windy night of the power cut, but it was mostly notorious for the flooding affecting large parts of Britain, most notably York and the Severn valley. They were the worst floods in SE England since 1968. The Record Flood Level for 7th November still stands on the Arun at Amberley Castle.  Summer 2007 flooding – the Severn again, and the Avon around Tewkesbury; also northern England. The southeast’s again turn in December 2013 (see notes from the time), with gales on 23rd December and flooding along the Mole, Wey, Arun amongst others on Xmas Eve. Even worse in Cumbria / northern Britain, with the  floods in  2005, 2009 and Storm Desmond in 2015.

Memories of the The Great Storm haunted me two years later as I fought, and eventually, but only just pulled through my own internal storms. I left uni’ with a very good degree, yet my mood and outlook were lower and bleaker than I’d ever known. Getting out and about into the countryside and along the rivers of Surrey, Sussex and Hampshire continued to give me some relief from this. It was a fine, warm summer and the woodland was slowly but surely recovering from the storm. Trees had been replanted and were regrowing.  In July 1989, though, I began to feel more definitely unwell. Come September, I was in hospital. I won’t repeat the details here (more in my ArtyTransplantee blog) but I was diagnosed at King’s College Hospital with autoimmune hepatitis (AIH, then called Chronic Active Hepatitis, CAH). Completely unrelated to alcohol, my body had been producing autoantibodies attacking my own lover. In early October, I received some heavy news at my bedside (as did my mother) that the AIH had advanced to the point the damage to my liver was irreparable and irreversible. My only hope was a transplant. As the doctor spoke to me, images from the night of the Great Gale came into my mind (the swaying lamp post at; the bare hillsides in the months afterwards, likened to the scar tissue of my damaged live). I felt as if I’d been struck my own devastating hurricane.

I must have been very near, or at the very top of the waiting list as within hours of being put on it, I got my transplant. Unlike most other people, no time to think about it; I just did what everyone told me to do in preparation (the pre-med) and got on with it. After a massive, ten hour long operation (knocked out and completely oblivious) I woke up in ICU (the transplant room), “It’s all over now.”, was the first thing I heard (from a doctor) when I came round. I couldn’t immediately see, but I was on a ventilator and wired up to lots of drips and tubes. In due course over the next few hours and days, most of these removed, but after such a massive operation, I knew I was in for a long haul. I was lucky to recover quickly, with no complications; but there were risks (infection nd rejection). All told I was in hospital for ten weeks: five before the TP, five afterwards. Coincidentally, I got my TP a few days before the second anniversary of the Great Storm. As I’d been warned beforehand, there were highs and lows. One of the blips came on the night of 15th / 16th October. I had a fever of about 38.9oC, and I felt myself overheating. My suspicion that this was rejection were right, but it subsequenty calmed down / was brought under control by taking more steroids. I was reassured by one of the junior doctors, before drifting off to sleep. I can’t have been asleep for more than about an hour, but in that time, a burst of short but very vivid dreams. My brain translated the fever into images of a stampede in Marks & Spencer, followed by a images of a a tower looking a bit like the Oxo Tower by Thames in London, transplanted to a garage I must have vaguely remembered from childhood holidays in the Forest of Dean; the feeling of overheating / something shooting up and up and about to blow. I woke up just before it did, but I was physically and mentally disorientated. It must have been post-op muscle weakness and exhaustion, through ac of sleep, maybe lingering effects of all the drugs I was on, but I couldn’t move. I thought the nurse watching over me was writing a report about me (the kind of report people tend to write after someone causing trouble) but it was just a letter home to a friend Down Under. I thought I’d been out for much longer – days. When the daylight came, I asked one of the nurses, “Is it Monday the 16th today?”. I thought right, but had to ask. No clocks or calendars visible from the bedside, it was easy to get confused. As the day went on, I felt more alert and re-orientated.

While my parents were visiting a few days later, we talked with one of the other nurses remembering the night of the storm. She’d been on night duty. That October (1989) a windy night a night or two later. It didn’t help that one of the windows in the side room I was in was in a state of repair and taped up, but the nurse looking after me was anxious. She called someone in to check the window. No problems, though like now (2017) a very mild autumn, the high one day that October was 19oC. Heating on in the hospital on October, whatever. Though the fever had gone, I still felt hot all the time.

Strange Skies

Monday 16th October 2017

Ex-Hurricane Ophelia lashes Ireland - Red suns and eerie skyglow - darkness in the balmy (barmey) early afternoon - Heatwave and wildfires on the continent

On this day, 30 years ago, 1987 - The Great Storm
October 15th / 16th

I started writing all this just before 2.00pm on Monday afternoon; blissfully unaware of the infernal car trouble my other half was involved in up the A3. Thankfully he was OK, but I'm glad I didn't know about it at the time. Meanwhile a sketching friend of  got out and about solo for the first time in a long while as his confidence began rising again a prolonged low earlier in the year.

Outside, the sky has been darkening over the past couple of hours. It’s dark enough now to feel more like dusk in November.. This follows the “red sun” around midday. After a cloudy, misty morning with some sunshine coming through, I noticed around midday, the sunlight coming into the artroom was weak and pink. The feel of light at sunset on a calm, misty midwinter day. Outside a pale pink sun shining through a hazy sky.  I have all the lights on downstairs. Ireland and Northern Ireland have been bearing the brunt of Ex-Ophelia today.

 This started off as Hurricane Ophelia in the Azores. It weakened into an “ordinary” low pressure system as it moved north into the cooler north Atlantic waters around the British Isles; but still the potential for very strong winds. The track of the storm is to the west of the British Isles. The Met.Office have an amber warning out over Northern Ireland, Galloway, north and west Wales; and a yellow warning throughout western Britain up to Loch Linnhe at the SE end of the Great Glen. Subject to refinements, the yellow warning has been there since the weekend. 

Being well east of the storm's track and outside the warning areas, I  wasn’t expecting much to happen here; just breezy-to-blowy; wind speeds in the Southampton area  to be around 20mph,  gusting to upto 37mph – noticeable, but not exceptional or damaging); and continuing very mild. A high of 20oC forecast for Southampton today. 

According to BBC News, the red sun has been seen around large parts of England: they say mainly the north and west. Photos from various places initially northern and western parts of England, later the south coast and London. One from Portsmouth, with the Spinnaker Tower against a dark sky with a hint of yellow glow "I promise, no filters".  Apparently, as Ex-Ophelia has tracked north, it’s picked up dust from the Sahara and debris from forest fires in Spain and Portugal. The dust in the air scatters the blue light, making the sun appear red.

14.10 – sky cloudy, still grey but brightening again
My other half meanwhile has hopped across The Channel for work, where  There it’s 25C. Yet again, like last autumn and the one before that, continental Europe is stuck under high pressure and western Europe, certainly very dry. Though weather forecasting has come on in great strides compared to 30 years ago, they still can’t be sure what the weather over the winter would be like. It could go either way. At the moment I’m concerned simultaneously about another floody winter in the north, which we could all do without; and the Loire amongst other rivers in western Europe continuing to be afflicted by chronic drought. For three or four successive autumns and winters now, western Europe has been stuck under high pressure for months on end. Last winter, as noted in my earlier blogs, it persisted over the UK, too. Thanks to rain during the summer and early autumn, the water outlook in the UK has improved in the short term, though for the most part, the track of the jetstream has been carrying the low pressures mainly over northern and western areas, missing the SE and the western continental Europe. It has also been very mild. From a river perspective, then, the further north the better. During our Scottish Borders stay last month, the Tweed was running well. Likewise the Greta and the Derwent around Keswick. Last week (10th - 11th October), there was a flood warning on the Cocker after heavy rain in Cumbria, along with flood alerts throughout Cumbria and the north Pennines. As usual for these rivers, they dropped back quickly after the rain stopped and I didn't hear of any flood related problems. The soils in the area, however are saturated / close to saturattion, meaning the rivers are responsive to any further rain. In southern England, flows on the Itchen and Test have stabilised, though as I suspected from trips to Salisbury over the summer, the Avon is still quite low. In the Canterbury area, the Great Stour has been bumping along the bottom. Groundwater levels in the Chalk have still been falling. Recharge this season will be from a low base.
