Description of Central Region Hydrologic Service Areas

Table of Contents: Page 1. Purpose ...... 2 2. Description of Hydrologic Service Areas ...... 2

1. Purpose: Each Weather Forecast Office (WFO) is responsible for a Hydrologic Service Area (HSA). These areas are typically the same as the County Warning and Forecast Areas (CWA) however, there are some differences. The purpose of this supplement is to provide detailed descriptions of the HSAs for each WFO and to cite where there are differences between the HSA and CWA. Each WFO is responsible for communicating these differences to emergency managers to ensure they know from which WFO they will receive river forecasts and warnings. 2. Description of Hydrologic Service Areas: In Central Region, most WFO HSAs align with their respective CWAs. Where rivers form the county line and border between two adjacent CWAs, that stretch of river is assigned to one of those WFO’s HSAs as noted in the HSA descriptions that follow. Where HSA and CWAs have minor differences, a reference to the other CWA is noted. The few minor differences that exist are justified hydrologically (e.g., a WFO has an entire river in their CWA except for a small portion at the mouth of the river, which is retained in their HSA). Forecast and warning products for points or reaches of a river are provided for the HSA while hydrologic products for counties or portions of counties are provided for the CWA.
