Yes, so, there's a lot of commonality in terms of England and Wales in terms of the systems that we use. So, the forecasting platform that we use is the same. The history of the models is the same, and similar. I think there are some differences. I think when colleagues were talking about a gap, they were talking about the potential, I think, of a gap increasing into the future, and divergence, potentially, between the different organisations, and that, potentially, presenting challenges for the Met Office, for example, working on a UK level and in terms of how they provide that data to different organisations.
There's also a gap when it comes to surface-water flooding, and there was a lot of talk in the last session about probabilistic forecasting and ensembles, which is quite complicated but, in essence, it's about looking at how forecasts may evolve and what the range of possibilities are into the future. No organisations are using that probabilistic forecasting for issuing flood warnings; we're all using the same information in terms of issuing flood warnings. So, that probabilistic forecasting is very much something that's being looked at now, for the future and for the potential of it.
I think it's true to say that in England, they have again invested some time to look at that potential. We work really closely with the Environment Agency and share information across the border both ways. We're interested in that work, but that is an example of some work that has been funded by the Met Office and the Environment Agency, and is being taken forward predominantly within England.
There are some differences, though, in terms of the here and now and, again, it gets a bit technical, but there are some differences in terms of how some of that reasonable worst-case information is processed. In essence, in simple terms, in England, they've introduced the ability to process that using computer information. We do it a bit more manually in Wales at the moment, but we're using the same base information. There is an important point here, I think, about the information that is used for the warnings, and the information that is used for the warnings that go out to the public is essentially the same in England and Wales.
So, when people are talking about a gap, I think they're talking about the potential for a gap, going forward. We need to work hard to make sure that that's not necessarily the case. I think it's a case of, there's risk there, but we also need to respect that we're different organisations with different priorities, and we might choose to do things slightly differently. There are other issues that are common across the border, when it comes to radars and radar coverage, and we do want to work collaboratively—and we do work collaboratively—across the border, and with the Met Office, and with the Flood Forecasting Centre.
