If you'd read your link you'd see that they said that average rainfall alone would not be enough to get drought areas out of drought.
They did indeed. But from the link:Trevor Bishop, Head of Water Resources at the Environment Agency
'A longer term drought, lasting until Christmas and perhaps beyond, now looks more likely – and we are working with businesses, farmers and water companies to plan ahead to meet the challenges of a continued drought.'
According to the OED a drought is "a prolonged period of abnormally low rainfall, leading to a shortage of water."
I don't think there's much doubt about what Mr Bishop meant. And on this occasion he got it wrong, although I don't think that lessens the need to conserve water supplies.
