As a market town at the base of the Pico de Orizaba, on the Puebla side of the volcano, Ciudad Serdan has its own character, but its weather follows the same Puebla pattern as everywhere else in the state: afternoon convective storms off the Sierra Nevada volcanoes, Popocatepetl and Iztaccihuatl.
Flash flooding in historic centers and valley towns shows up often enough in this part of Puebla that it's built into how people in Ciudad Serdan think about the weather, not treated as a rare event.
Ciudad Serdan's radar coverage draws on Mexico's national water authority, CONAGUA, with scans updating every 5 minutes. What lands on the map is the rain itself over Ciudad Serdan — not an averaged forecast for the surrounding region.
Ciudad Serdan's busiest stretch for rain lines up with the rest of Puebla — this is when storm activity peaks for the year.
