Bimba Sjöholm was completing her second lap during the Q3 shoot-out for qualification for the second round of the UIM F2 World Championship when she dramatically blew her Molgaard hull over.
The Swedish driver who crashed out of round one while leading the race had posted the second fastest time of the session when the wind suddenly got up.
With white horses appearing on top of the Portuguese river Bimba was caught by the gusts.
The popular driver walked away from the accident in good health.
The session was immediately postponed until tomorrow.
A full qualifying report will follow.
