Ferrari boss Stefano Domenicali admitted his team made an error of judgement during qualifying for the Malaysian Grand Prix.
Both Fernando Alonso and team-mate Felipe Massa were knocked out in Q1 after waiting too long to set their first timed lap.
The drivers took to the track when the conditions had worsened and so it was impossible for them to set competitive times.
Domenicali conceded the team had simply made a mistake, putting too much trust on the weather forecast.
"We are very disappointed with the way qualifying went," said Domenicali. "We made an error of judgement in trusting the weather forecast: when we went out on track the rain, rather than dying down, suddenly got even stronger.
"With hindsight, it is easy to say we should have gone out immediately. It's a real shame because all the signs were that we could have done well and now we will have to prepare for an uphill fight in the race.
"But there's no point in crying about things before they have even happened, because the race is not until tomorrow. And as we saw today, anything could happen. We will try and pick up as many points as possible, making the most of any opportunity that presents itself."
