Executive Director for FISA, Mr Matt Smith said the concerns were 1. Extreme heat and worries about intense exposure to sun rays and 2. uncertainty about the arrival of thunderstorms. "It was considered better to get the races completed in the best possible conditions rather than wait for the afternoon," said Smith.
