Frankie MacDonald is a Canadian amateur weather forecaster from Nova Scotia whose loud, enthusiastic storm warnings became viral on YouTube and later spread across TikTok and meme pages. His urgent style, with repeated warnings to stay safe and take cover, turned serious weather forecasts into shareable comedy. Clips pairing his voice with sirens and storm footage are now reused whenever creators want instant alarm, exaggeration or chaos, keeping his distinctive warning voice recognisable long after the original forecasts.
