Fun! You must be familiar with those little wind bomblets that start around 1PM & arrive w/ no warning ... 45kts from a random direction.

Bet that's interesting if it happens in the middle of a race, too.
Personally, our tactic during those things is to reef the heck out of the sails & forereach for 15-30 minutes until the beast passes. Who knows, racers may keep on truckin.' (It does suck when you run out of lake before the sky runs out of wind, tho.)
