What source did the German Met office used that time while here was MRF? If you know Darren, thanks.
It was their own DWD model, which is still going today - we know it as the ICON these days.
There was also the French Arpege model in use, and that was the one that correctly forecast the track of the Great Storm in 1987. It was an outlier, though, compared with our own MetO model... so the Met Office dismissed it. The rest, as they say, is history!
(In reality, all the European weather bureaus back in the 80s/90s would have shared their data, much as is done today. Again, the difference is we didn't get to see any of it, just the overall summary!)
