They sell some pretty cool PWC goggles at Overtons that work great in those conditions. 2 years ago I was caught 1/2 hour from the launch in a pretty good thunderstorm on my PWC. Even with the painfull sandblasting I was recieving from the downpour, the urge to slow down was far surpased by the motivation from seeing all the lightning strikes all around. Very nerve racking.
