At that rate, anyone else would be fired! I think that anyone could do as good a job as they can. In fact, there's a guy in New Zealand who predicts the Irish weather months ahead of time and 8 out of 10 times he's right! He had more accuracy than the people here!
But it is funny to watch though. This weather woman here predicted storm three days in a row last year, in the spring, and kept predicting storm at least once a week. We had none of it. Instead, we had 12 weeks of sun, no storm, no rain...LOL, She was getting more frustrated by the day! I think it's mostly guess-work anyways.
