Introduction
-Objective
The intent of this project is to establish methods to transfer information
between WFO and RFC WFO Hydrometeorological Forecast System (WHFS)
databases.
-Need
The WHFS databases exist at both WFOs and RFCs. Identical hydrologic
stations, and supporting elements that together uniquely identify
each site, exist in multiple offices' databases. NWS offices routinely
add, delete, or modify these elements daily. Communication of these
changes to all interested offices is essential to ensure they are
consistently propagated through the system. Inconsistent entries
can lead to confusion, and damage each office's capabilities to
provide adequate hydrologic products and services.
- Benefits
If an NWS office can be made aware of changes occurring at another
NWS office, all affected offices will know to address inconsistencies
in the system. Thus they can begin to take positive steps to ensure
that identical station definitions at each office is updated in
a reasonable time frame.
