NTSB Safety Recommendation — Aviation
Recommendation text
TO THE NATIONAL WEATHER SERVICE: Revise National Weather Service Instruction 30-2112 to provide operational (forecasting) staff at weather forecast offices the authority to determine whether report processing for an automated surface observing system sensor at an unattended site (or other site not currently being appropriately augmented) should be turned off immediately if the sensor is believed to be reporting erroneously but does not yield flags in its maintenance monitoring data and to include clear instructions for performing this task.
In plain language (FlightFinder summary)
The National Weather Service is asked to update its Instruction 30-2112, granting forecast office staff the authority to immediately turn off report processing for an automated surface observing system sensor at unattended sites if the sensor is believed to be reporting errors, even if maintenance monitoring data shows no flags. The revision must also include clear instructions for performing this task.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
