SEA is amazingly friendly. They get rain but not very intense. What makes it particularly challenging is that it is rain specifically across the path of the link. So a 1km link that follows a typical squall line path will be different than a 1km link that is perpendicular to the typical squall line (partial path with rain vs. full path with rain). It's cool stuff like this that makes it so much fun! :-)
