Cornwall is not known for being prone to natural hazards , although they do happen . The county experiences droughts and heat waves with the rest of Europe as they happen , but its location close to the ocean dampens their severity . Also , European windstorms in the winter usually make landfall on the west coast of Europe , including Cornwall , resulting in severe gales and flooding . Cornwall 's large amount of valleys also make it prone to rapid flooding when an unusually heavy amount of rainfall occurs , as seen in the Boscastle flood of 2004
