A family in Watford, UK, narrowly escaped a house fire caused by a lightning strike that struck their six-bedroom home while they were asleep. A stranger alerted them to the thick black smoke coming from their roof, and they evacuated just in time. The fire spread to the loft, causing extensive damage and an estimated £60,000 repair cost. The family is appealing for the woman who warned them to come forward.
