16th century weather report?

RIGHT: though I suspected a sub-text, this black letter broadside, printed “at London in the Olde Baily by Richard Lant for Thomas Porefut in Paules Churchyard at the sygne of Lucrese”, seems to offer a straightforward account (in a translation by Renolde Olyver) of a violent storm and consequent disasters that took place at Mechlin [Malines], near Antwerp, in August 1546.
