Narrative:

During rollout after landing; the aircraft accelerated and turned sharply right hitting a runway taxi light. The light tore the skin on the left fuselage side underneath from the cowling to almost the empennage. The aircraft continued rapidly across the taxiway onto the dirt until just before the parallel taxiway before I was able to stop. The light impact and aggressive braking had no effect to slow the aircraft. I believe a 'dust devil;' a swirling wind; struck the aircraft on the left rear quarter pushing the aircraft to speed up and turn right. To prevent a recurrence would for me to be highly alert to such a possibility of an aberrant runway wind and more aggressively add crosswind correction.
