[2017 Apr 20] Network maintenance, possible site outage
Continued network maintenance is scheduled for Thursday April 20 from roughly 1000 UTC to about 1800 UTC. The aviationweather.gov website might encounter intermittent outages of both connectivity and data.
[2017 Apr 17] IDP network maintenance, server issues
The web provider, IDP, performed some network maintenance Monday, April 17th. This caused some weird side effects which resulted in the server being down, then an inability to receive live data. The server outage was from 1545 to 1650Z. The server data issues continued until 2030Z when the data flow was fully restored.
[2017 Apr 03] ADDS Database issues, lack of live data
At about 1730Z today, the ADDS database replication stopped. Even though data were getting into the master database, it was not getting to the slave servers, meaning data was frozen at 1730Z. The web IT staff at IDP have reset the database servers to get live data flowing again. As of 2230Z, some data flow has been restored. AWC and IDP will monitor the situation.
[2017 Feb 15] TCF (TFM Convective Forecast) is now available
The NWS Aviation Weather Center (AWC) has begun production of the Traffic Flow Management (TFM) Convective Forecast (TCF). TCF is a high-confidence graphical representation of forecasted convection meeting specific criteria of coverage, intensity, and echo top height. The TCF is used by air traffic management decision makers in support of convective weather mitigation strategies within the National Airspace System. The TCF may be accessed at http://www.AviationWeather.gov/tcf

[2014 Jun 22] Altimeter observation errors
The altimeter observation errors have been resolved from Saturday night except for three sites: Meeker, Colorado - Eagle, Alaska - St Paul Island, Alaska. These will be repaired shortly
[2014 Jun 21] Warning: altimeter observation errors
Please exercise caution when using altimeter observations!
Widespread altimeter observation errors may be possible across the southern United States due to a possible software error. Technicians are currently checking altimeter settings at sites where errant software may have been deployed. The reported error was caused by the trailing zero of the elevation at the observing site being removed. For example, an elevation of 3620 feet was listed as 362 feet. This error will result in incorrect altimeter calculations. While the error was caught before the software was pushed across the country, the National Weather Service Southern Region reports that up to 600 sites may have been impacted.
This error is expected to be fully corrected by Sunday morning.

[2014 May 07] NTSB provides NWS with safety recommendations.
The National Transportation Safety Board has issued a recommendation to both the Federal Aviation Administration and the National Weather Service Tuesday, urging both agencies to work toward placing more weather information in pilots' hands.
The NTSB wants those agencies to do a better job in sharing more real-time weather information with pilots, and do a better job of teaching them about dangerous weather conditions they may face.
The NTSB made the following five recommendations to the NWS:
The full report can be downloaded here
- Modify NWS aviation weather products to make them consistent with NWS nonaviation-specific advisory products when applicable, so that they advise of hazardous conditions including aviation hazards less than 3,000 square miles in area that exist outside of terminal aerodrome forecast coverage areas. (A-14-17)
- Provide a primary aviation weather product that specifically addresses both the potential for and the existence of mountain wave activity and the associated aviation weather hazards (as recommended in Safety Recommendation A-14-14 to the FAA). (A-14-18)
- In cooperation with FAA, revise the Interagency Agreement between the FAA and the NOAA for the CWSU and its accompanying statement of work if needed to add the new responsibilities of CWSU personnel in response to Safety Recommendations A-14-17 and/or A-14-18 to the NWS, which are in addition to the other responsibilities currently performed by the NWS under this agreement. (A-14-19)
- Establish a protocol that will enhance communication among meteorologists at the CWSUs, the AWC, and, as applicable, other NWS facilities to ensure mutual situation awareness of critical aviation weather data among meteorologists at those facilities. (A-14-20)
- Establish standardized guidance for all NWS aviation weather forecasters on the weighting of information reported in pilot reports (PIREPs) that will (1) promote consistent determination of hazard severity reported in a PIREP and (2) assist in aviation weather product issuance. (A-14-21)
