Pour the concrete onto the existing damaged concrete in the same way and trowel to a smooth finish and hopefully there is no more rain to cause any damage.

The reason why builders avoid pouring concrete in rain deals with the overall strength of the concrete. The integrity of the slab depends on keeping the water ratio in the concrete mix low.
