I made it back to camp with only a few sprinkles. About 10 minutes after getting back to camp and securing the Hex 2 for rain the downpour of rain and hail began, along with lightning. Dave and Jim were still out there, so I radioed them to make sure they were okay (some of the thunder echoed in a way that sounded like rockfall. Considering the slope we had just been on, this made me nervous). They got back about 10 minutes later, soaked. The storm only lasted about 20 minutes, then it was time for the sky to clear and dry us out.
