After a few days of double storms spawning, it seems like we have a clear weather forecast, as storms are once again down to one at time, sometimes down to zero.
This is like a bug and not intentional. This issue started Friday around the daily reset time. Friday is also the mid-week World Quest reset day, but it is unsure if something then caused it. Checking the Primal Storm Tracking spredsheet you can see that storms started having issues on both issues around the same time relative to the weekly reset.
Another evidence that the issue is the same in both regions is that the storm supposed to spawn 84h after the weekly reset on both regions didn't spawn, leaving that window stormless.
