Rain in San Bernardino: What You Need to Know
San Bernardino is a smaller community within the State of Mexico, and like the rest of State of Mexico, its weather is shaped by afternoon convective storms across the crowded municipalities ringing Mexico City, several built on the drained bed of former Lake Texcoco.
Practically, that translates into rapid drainage overwhelm within 20-30 minutes of storm onset as a real factor for San Bernardino, something residents plan around rather than get caught by.
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 Bernardino rather than a generic probability for the wider region.
