”— The Stormfather to Dalinar during the Battle of Narak. THEY CALL FOR A STORM. MY OPPOSITE. DEADLY
The Everstorm is a powerful weather pattern on Roshar similar to a highstorm. The Everstorm was summoned by Stormform Listeners during the Battle of Narak at the end of the War of Reckoning. It appears to be referenced as being the same thing as the True Desolation by Honor in Dalinar's visions, but it is possible the Everstorm is only a part of the True Desolation. According to Sylphrena it has not been summoned in previous Desolations. It may also be referred to as the 'Evernight'.
Where regular highstorms are products of the Stormfather, a splinter of Honor, the Everstorm is not of Honor. It is of Odium. The storm travels from west to east, opposite the direction of traditional highstorms. It attracts stormspren and has the unique physical feature of red lightning.This has obvious and terrible consequences for the other inhabitants of Roshar. Because of the Everstorm's backward path and unexpected summoning, Rosharans will be nearly defenseless against its destruction, as both stormwardens and physical barriers will be useless against it. It is noted that it will round Roshar less frequently than a highstorm. It also has the side effect of releasing Parshman who come in contact with it from Slaveform. The biggest advantage for Odium, however, is the Everstorm allows the Fused (ancient Singers) to be reborn in the next Everstorm when killed instead of returning Damnation as in past Desolations. The characteristics of the Everstorm can vary greatly even within the same passing, for instance, some reports mention red lighting with no wind, while other reports state that burning embers fell instead of rain.
As Alethi forces approached Narak the Listeners awaited them and began singing a new song. Rlain warned Dalinar that the song should not be allowed to be finished under any circumstances. Dalinar subsequently ordered Adolin to stop the song at all costs. A daring attack was launched by Adolin on a group of reserve Listeners, who were leading the song. During the battle, Adolin defeated the Parshendi Shard bearer Eshonai, but they were too late.
The Everstorm crashed into a regular highstorm, which was produced by the Stormfather. The resulting tempest was capable of breaking and throwing entire plateaus from the Shattered Plains into the sky. 
In Yeddaw Lift heard reports that the Everstorm had started to strike countries in the west of Roshar. It was reported to be moving slower than a regular Highstorm. She was present as the storm struck Yeddaw. There was no stormwall as in a regular Highstorm. Nale saw the storm and parshmen wearing Stormform and was convinced that he failed in preventing the return of the desolations.
The Fused are ancestors of the singers. They are bonded with a modern singer, which this kills the singer they bonded with, and have access to powers similar to surgebinding. If a Fused is killed they are reborn during the Everstorm, assuming they can find a parshman body willing to latch onto, or at least one that cannot refuse entry of a Fused.
The Everstorm typically moves at a much slower rate than highstorms, with an average speed about three times slower. Kaladin notes that one has plenty of time to seek shelter after spotting the storm's arrival. At these speeds, the Everstorm takes nearly three days to cross the mainland of Roshar. The Everstorm returns at fairly regular intervals of approximately nine days, seeming to circle the planet. Though the recurrence is much more regular that of the highstorms, the time of arrival does fluxuate slightly, and precise predictions for the arrival time are sometimes inaccurate. It is not yet clear whether the frequency of the Everstorm's arrival is affected by the time of the year or other variables. Odium appears to exert some measure of control over the Everstorm's speed. On the day of the Battle of Thaylen Field, he caused the storm to arrive 4 days earlier than usual--crossing most of Roshar within a day--before stopping it in place until it dissipated at the end of the battle. The Everstorm seems to have resumed it's normal nine day cycle following these events.
