In the event of visibility being reduced to less than 50 metres during market operations (due to dense fog), the market manager will have discretion to cancel or close the market early
Os bydd gwelededd yn cael ei leihau i lai na 50 metr yn ystod amser agor y farchnad (oherwydd niwl trwchus), bydd gan reolwr y farchnad yr hawl i ganslo neu gau'r farchnad yn gynnar
