For other uses, see Portal (disambiguation).
A Portal Storm is an event that creates a multitude of portals to other dimensions. As seen in Half-Life 2: Episode Two, these portals spread outwards in a storm-like manner, causing havoc wherever they hit.
Since the Resonance Cascade at Black Mesa, Portal Storms have occurred all over the world bringing forth life forms from Xen. They are a highly dangerous and destructive phenomena, capable of inflicting severe structural damage to objects, such as buildings and bridges. A Portal Storm consists of a blue 'wave' which resonates from a portal and moves across the landscape.
In Half-Life 2, when at Black Mesa East, the player can see a newspaper cut-out, titled "Portal" Storm Continues. In Episode Two, a series of Portal Storms originating from the Superportal ravage the surrounding landscape.
