...SYSTEM UPGRADE SERVICE INTERRUPTION JUNE 2-4, 2025...

The WFO National Weather Service office in Flagstaff, AZ will be
undergoing a computer upgrade of their systems that require some
regular products and services to be unavailable between Monday, June
2 and Wednesday, June 4. This includes suspended service of the NOAA
Weather Radio transmitters and some routine climate text products
such as the Daily Climate Report (CLI), Preliminary Monthly Climate
Data (CF6), and Routine Temperature and Precipitation (RTP). These
products and services will become unavailable the morning of Monday,
June 2 and resume Wednesday, June 4, late in the day.

Many of the locally generated graphics and data on weather.gov/fgz
will be temporarily unavailable during this time. This includes the
forecast graphics page, fire weather pages, recreation weather page,
and the Grand Canyon Heat Risk page.

The forecast office will continue regular operations during this
time with all other normally scheduled products and services
continuing uninterrupted.

We apologize for any inconvenience this temporary suspension of
these products and services may cause. The observation data used to
create the impacted climate text products will still be available
for users throughout this timeframe.

We encourage users in the area to have multiple ways to receive
warnings and to ensure they have Wireless Emergency Alerts turned on
on their phones.

If you have any questions, please feel free to email the office at
nws.flagstaff@noaa.gov.
