The first night on my trip to a tri-regional AOC rally at Thermopolis, Wyoming, was at an RV park in Winnemucca, Nevada.? The wind blew the rain up into the peak area and I had a waterfall across the Aliner.? Sadly, my vehicle key were directly under that waterfall.? I could not continue on the trip until the vehicle was towed to a nearby Jeep dealership where they could remove the alarm from the vehicle so I could start the vehicle with just the hard key.
So water entering across the peak can happen.
