The Austin/San Antonio Texas National Weather Service Office has implemented Advanced Hydrologic Prediction Service (AHPS) for the San Antonio River Basin in South Central Texas. AHPS enables the National Weather Service to provide long-range probabilistic outlooks. This service is also available on the Internet. In the table below, the 90 through 10 percent columns indicate The chance the river could rise above the listed stage levels in the next 90 days. Example: The San Antonio River at Elmendorf has a flood stage of 35 feet. There is a 50 percent chance the Elmendorf forecast point will rise above 30.5 feet during the next 90 days.
