Does storm hit under dark swarm?

Question

I just wonder what effects does a storm from Templar has under a spell cast by a dark swarm cast by defiler. Does it deal any damage at all? is the damage reduced.

I wanted to test it myself but its hard to control 2 races at once with both of the abilities researched.

Answer 1

All special abilities (like Psionic Storm) hit under the cloud, as well as ranged splash damage (such as indirect siege tank fire) and of course melee attackers.

Blizzard's Starcraft Compendium is a great resource for questions like these.
