This symbol means Disruption Hagalaz: (H: Hail.)
If we get this glyph it could be interpreted to mean,
Area of possible crisis leading to transformation. Stormy weather ahead leading to sunshine. Wrath of nature, destructive, uncontrolled forces, especially the weather, or within the unconscious. Some confusion before order. Tempering, testing, trial. Controlled crisis, leading to completion, inner harmony. Uncomfortable beneficial adjustments. Hail is frozen water—as it melts it nourishes the Earth. A temporary disruption before order and replenishment returns.
Hagalaz Merkstave (Hagalaz cannot be reversed.)
Drawing this Rune shows us that we might experience some disruption of events that seem to be totally beyond our control. It might take many forms: a relationship may fail, plans go awry, a source of supply dries up. We need not be dismayed. We are with power in this situation even though we might have created the disruption ourselves – we have our own inner strength for our support in this present or approaching challenge – an opportunity for growth! Life is going to get uncomfortable – this Rune is a good omen for it promises better times to come.
