Known as a community in the Zumpango area of the northern state, San Juan Zitlaltepec sits within a broader State of Mexico climate pattern driven by afternoon convective storms across the crowded municipalities ringing Mexico City, several built on the drained bed of former Lake Texcoco.
For a place like San Juan Zitlaltepec, the consequence is rapid drainage overwhelm within 20-30 minutes of storm onset — a documented pattern across State of Mexico that a same-day forecast tends to miss.
RainViewer's radar data for Mexico comes from the Comisión Nacional del Agua (CONAGUA) — Mexico's National Water Commission. The map updates every 5 minutes, showing the actual rain over San Juan Zitlaltepec rather than a generic probability for the wider region.
