IRONMAN legend Grant Kenny was struck on the head by a hailstone during a ski paddle.

The damage bill is still being tallied after the Sunshine Coast was bombarded by hailstones the size of tennis balls on Saturday.

The vicious storm carved a trail of destruction through the central parts of the Coast shortly after lunchtime, with Sippy Downs, Buderim, Mooloolaba, Alexandra Headland and Maroochydore among the worst hit.

Nowhere was more affected than Cotton Tree, where campers at the caravan park spent 20 minutes dodging the large balls of ice and watching their vans and cars being pelted.

Mr Kenny was on a ski paddle when the storm hit.

"The storm came over and hail the size of a cricket ball hit me as I paddled home. It drew blood and really hurt,'' Mr Kenny told News Corp.

"I rolled my ski over and hid under it.''

The Bureau of Meteorology forecast for today is partly cloudy with the chance of isolated showers and thunderstorms, mostly in the afternoon.
