Yes! It might take you by surprise, but rain is possible over the cooler winter months in Doha, Qatar (or it could stay completely dry!) We wouldn't recommend packing your umbrella just in case - but do expect sheer pandamonium if it does as buildings are put to the water-tight test; roads become easily flooded and most drivers don't know how to react. Best to stay in place if a rainstorm does hit, it will soon pass.
