The Austin/San Antonio Texas National Weather Service Office has implemented Advanced Hydrologic Prediction Service (AHPS) for the Guadalupe 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 Guadalupe River at Gonzales has a flood stage of 31 feet. There is a 50 percent chance the Gonzales forecast point will rise above 23.8 feet during the next 90 days.
