I remember monsoon season from Vietnam. 40 straight hours of deafening rain, then 3 days of 100 degree, humid days. Then 40 more hours of rain. And 4 days of hot and humid to soak the water back up into the clouds. Then, yep. 40 more hours of rain. What we DIDN'T see was 185 mph winds! And there was nothing even resembling a sewer system so the who base camp had boardwalks that were 18 to 20 inches high so we had somewhere to walk to work. Trucks could move, but jeeps were too low to handle the water. The snorkel air intake was fine but the body was not built like a boat hull. LOL!
Chulaivet was there too and I am sure remembers monsoons.
