Jason,
no, nothing quite like that. Thankfully!
SEPA use lots of data to predict possible outcomes. This is really a worst-case scenario view. But, VERY possible!
Given the positively Biblical rainfall we seem to encounter more and more currently, it may well not be far away.
I don't think we get any MORE rain than I can recall in my lifetime, it just seems to come in greater individual bursts now more than evenly spread over the year.
FBD.
PS can anyone remind me how to shorten that loooooong url???
