As an agricultural town in the central Baja California Sur desert, irrigated by deep wells, Ciudad Constitucion has its own character, but its weather follows the same Baja California Sur pattern as everywhere else in the state: tropical cyclones and hurricane remnants moving up the Pacific coast -- up to half the state's annual rainfall comes from named storms.
Ciudad Constitucion isn't exempt from flash flooding in normally-dry arroyos and washed-out highways, a pattern common enough across Baja California Sur that a live view of the weather beats a general forecast.
Behind the Ciudad Constitucion rain map sits CONAGUA data, refreshed on a 5-minute cycle. That means the map tracks actual precipitation over Ciudad Constitucion, not a statewide estimate.
Like the rest of Baja California Sur, Ciudad Constitucion sees its heaviest rain during a defined stretch of the year, when storms are both more frequent and more intense.

Storms tied to tropical cyclones and hurricane remnants moving up the Pacific coast -- up to half the state's annual rainfall comes from named storms can build faster than a typical commute takes. A quick radar check first beats finding out halfway there.
