Storms are ok, and I'll probably always keep them on, though I do have two issues with them.
The first is that the storms hit too quickly. If you are between towns, 60 seconds isn't always enough time to make it to a POI, and having to rapidly construct a tiny shelter is possible, but also incredibly boring to sit inside while waiting the storm to eventually subside. This sudden hazard onset makes me want to avoid non-forest biomes. I think a 2-minute or possibly even 90-second warning time would be much better.
The second issue is the huge amount of damage each tick does. I think taking damage is fine, but if it is this lethal, then a way to reduce it would be nice. Currently, badges do nothing, but I think they should offer some resistance against the damage. Alternatively, add an armor padding mod to replace the removed insulating and cooling mesh mods that reduces storm damage and give back the explosion resistance that those former mods also had.
