When I lived at the Oregon coast if I didn't smoke in the rain if only get to smoke a couple days a year! Some smokers do better than others in the rain. The WSM family rocks it in the rain. Just smoked a bone in turkey breast a day ago in a complete down pour. The Mini-WSM rocks in the rain. I put my iGrill in a plastic bag to protect the transmitter. Other than that I did nothing else special. Smoker ran at 350 for the 2.5 hour cook. At the end of the cook I closed down all the vents and let the smoker sit in the rain. Easy peasy!
