  1. Preparations and planning for the arrival of Storm Jocelyn. There has been disruption and cancellations all day in Scotland on the railways, not enough time to repair, check and secure everything before the next bout.
  2. Scotrail trains will have stopped again by 7pm on Tuesday and not run early on Wednesday
  3. There was so much news going on yesterday, it's been hard to catch up with it all today. So much disruption. Very glad the main part of the storm was overnight, at least many people had got home and retired for the evening.
  4. Maybe that is for the Regional discussion group rather than Storm Jocelyn 24 hours ahead? Also Met Office warnings are not based solely on numerical limits, especially in one location. They look at wider impacts. The process has flaws but it does need some understanding. There can be heavy rain outside of a Rain warning area, Snow the same. This was the matrix for Isha
  5. Storm Isha, this is Jocelyn for Tuesday night. I saw Glencoe mention that exact figure (not official) so ...
  6. IPMA in Portugal show the warnings in timeline style for regions which I think helps imagine a time period for severe weather arriving and clearing. We can have the same warning from Cornwall to Kent and the impacts will shift eastwards with time.
  7. Riding the storm - NATS Blog NATS.AERO It’s very rare for a storm to blanket the whole of the UK and Ireland, as Storm Isha did yesterday. Rarer still for it to deliver the strength of winds that it did. The challenge for the aviation industry is the difficulty for...
  8. But we can't tell where those thousands are located, loads in US seeing it on twitter doesn't count. No national TV broadcast had it in time for their late new and weather broadcasts at 10:30pm
  9. It is worth looking at the matrix for the various warning areas too, they are an important source of info. We have Scotland, N.Irelalnd down to N.Wales. (Medium impacts are possible) South Wales, MIdlands up to Newcastle (very likely to see low impacts here) And the Amber for N & W Scotland - see Pauls' post above. What these 3 levels of impacts are, is on the met office website
  10. Any national Met service can name a storm. They have their own criteria, Met Eireann issue warnings in a different way to the UK Met Office (who use impact based matrix, not numerical limits). The UK , Ireland and Netherlands are in a group (Western naming group) and discuss who will be most affected by a potential storm and then that country tends to name it., Often an Orange (or Amber warning) is issued too but they are separate things. Sometimes a different group name a storm that might still affect the UK, often Meteo France in the SW Naming group. Storm name is a communication tool - Warnings look at specific location/timings and level of Likelihood against Impacts.
  11. Rain by day Tuesday = flooding Gales ramping up Tuesday evening and overnight, disruption possible Weds am N and NE Britain
  12. "Further north conditions just about warranted the Amber warning, but I’ve still seen very few (I don’t think there were any) official gusts over 75mph for lowland stations away from exposed coasts." MO Warnings are about impacts. Our Amber was very much correct, here in Scotland
  13. No trains running in Scotland until after the morning rush hour period. Chaos on the network with fallen trees, damage to overhead wires, a shed on line, flooding. Nothing from Lothian Buses, no update at all this morning
  14. Chaos for the railway network this morning in Scotland which impacts routes south into England along east and west coast. No trains at all in Scotland until after the rush hour whilst the lines are checked in daylight, when it comes. Many incidents reported , trees, overhead wires, fallen wall, rogue shed
  15. So this happened overnight RED WARNING in NE Early Monday 01-05. UKV had the core of winds shown yesterday
  16. Brizlee Wood 99mph gust overnight "Remote Radar Head Brizlee Wood, is an air defence radar station operated by the Royal Air Force located at Brizlee Wood, near Alnwick in Northumberland, England"
  17. GFS shows there is more to come for Irish Sea and northern BRitain as cold front clears SE England
  18. There are quite a few official Flood warnings out from https://check-for-flooding.service.gov.uk/alerts-and-warnings and SEPA . Flood alerts in Wales
