Ask a meteorologist about the 1996 tornado thriller Twister, and they’ll either find it packed with howl-inducing inaccuracies, or enjoy it despite its flaws. Kathryn Prociv, a meteorologist and storm chaser, wrote in the Washington Post that she counts herself among the camp of weather buffs who love the film despite its scientific inaccuracies. However, that doesn’t stop her from highlighting some of the groaners in store.
