The darkness outside seems to amplify the sound of the water treatment plant's machinery, a soothing background noise that helps me focus on the screens in front of me. Current weather: a light drizzle starting to fall over Porto Alegre.

Tonight's calm before the storm, I suppose, as I watch the Guaíba's level, steady as my routine, yet the news of global markets keeps my console ablaze, a reminder that even in still waters, undercurrents run deep. Current weather: a gentle mist covering Porto Alegre.
