A stunned homeowner captured this stunning lightning flash in the skies above his home in Penzance, Cornwall, this morning. A fork of lightning can be see flashing across the sky before a deafening thunderclap startles dozing residents and a flock of seagulls who take to the air in fright. The thunderstorm came as the UK experiences a massive heatwave with temperatures soaring to their highest since records began. Twitter user @MyWifeDave captioned the video: "Forked lightning and seagulls going mad in #penzance #cornwall #storm #lightning where was the weather warning @metoffice"
