One of the biggest concerns is the electrical hazard of having a grill and electrical appliances near water. It's like playing with fire and water, and not in a good way – think shock therapy, not barbecue therapy. So, if you do decide to grill in the rain, make sure you're using a gas grill and keeping all electrical appliances under cover.
Another thing to consider is the ventilation – or lack thereof. When it's raining, the air is all heavy and humid, which means your grill might not be getting the oxygen it needs to keep on cooking. This can lead to a less-than-stellar grilling experience, and possibly even some food safety issues.
