The reason they asked about wet weather was to determine if the belt to the power steering pump was slipping. If the pump stops spinning, then the power assist to the steering is lost.

And this is an interference engine, meaning a snapped timing belt could ruin the engine. Consider this and get the accessory belts replaced with the timing belt. On this engine (1.7L 4-cyl), the water pump should also be replaced with the timing belt.
