Many cities on Ryloth were protected from these storms by encasing themselves underground, although particularly bad heat storms could make even caves near the surface temporarily uninhabitable. Twi'lek siren whistles were used to warn populations of approaching storms.
In the city of Kala'uun, mothers of Twi'lek children told a tale of two young lovers, Ko'lek and Oo'rha, whose lovestruck wanderings led them right into the path of a heat storm that killed them as they lay in each other's arms. The story was intended to discourage children from wandering in unknown tunnels beneath Ryloth's surface.
In 3986 BBY, the Twi'lek Jedi Tott Doneeta attempted to use the Force to wrangle a heat storm that sprang up to threaten an exiled clan under his protection while they moved amongst the mountains in search for a new home. As a result, he received severe burns to the left side of his face.
