Even with gear, you may get soaked! My sister and I had rain boots, rain pants, and full-length rain ponchos/coats with hoods. We'd seen weather reports of a huge storm expected during our trip so we shopped the night before we flew down. The storm hit before our first day and it was a doozy! We were heading from GCH to the DLH for our afternoon tea reservation, fully decked out, but the wind was freakish and the rain torrential. We got completely soaked in spite of our gear. On the plus side, Christmas-themed afternoon tea at DLH was worth the trouble!
BTW, before we arrived in Anaheim, Main St flooded and there were ducks swimming in the hub
