Current Status

NWS will remain on the PRIMARY server system until further notice. There will be no monthly transitions as in previous months. There may be outages planned and unplanned due to network re-configurations and "hot-fix" updates to resolve issues impacting NWS systems that may also affect NWWS-OI operation.

If your system is off-line or having trouble reconnecting after an outage, a system reset or restart should clear up the problem. If not, e-mail NWWS.issue@noaa.gov.

Please note that NOTICES for planned outages will be posted when known. Thank you for your understanding.
