As a smaller community in the Toluca Valley, San Francisco Coaxusco has its own character, but its weather follows the same State of Mexico pattern as everywhere else in the state: afternoon convective storms across the crowded municipalities ringing Mexico City, several built on the drained bed of former Lake Texcoco.
The stakes are concrete — rapid drainage overwhelm within 20-30 minutes of storm onset is a known issue here, and for San Francisco Coaxusco specifically, knowing a storm is building matters more than knowing it's merely 'possible'.
