Narrative:

Shortly before normal landing [tower] announced wind 090 at 8 kts. I proceeded with a crosswind landing approaching the runway with crosswind correction of left aileron and right rudder. All was a normal landing up and until shortly before left wheel touch down. I can only guess it was a gust. Left wing dipped dramatically down. Fearing a strike I corrected right and the right wheel touched down. I over corrected left and aircraft veered left and stopped to the left of the runway in the grass.
