Nathan Gunter : I like the big , full clouds , but watch them closely for signs of trouble . Gunter : But a small , ground-floor room with no exterior walls will do if the tornado is n't too strong . Green clouds are bad ; swirl at edge of a storm pattern means take cover . We ' ve had our share of disaster , he says : Murrah storm , previous tornadoes . Nathan : We make sense of it by helping out , finding meaning in acts of kindness .
