As indicated in the Spring 2025 MesoWest Product Change Notice, MesoWest will have a downtime on Tuesday, February 25, to change how it receives data into its legacy database. The data will come entirely from Synoptic Data PBC that bundles all the data into a single data stream. While this change should not impact the majority of weather stations available in our displays, we will reduce our support for some stations outside of North America and multiple same-sensor measurements (e.g., two wind sensors) at the same station. Some other minor changes in data feeds and availability may take place as well. There may be a short gap in data collected into our system on Tuesday, February 25, while the downtime takes place.

These changes will have no impact on the actual reception of data by Synoptic Data PBC. Users who require continuous records, or have multiple sensor systems, are encouraged to rely on Synoptic Data's Viewer (https://viewer.synopticdata.com/) as well as Weather API Services (https://docs.synopticdata.com/services/weather-data-api) for accessing complete data from the weather stations that have been available from MesoWest. These changes also will have no impact on data availability for the NWS Weather and Hazards Data Viewer (https://www.wrh.noaa.gov/map/), as observational data on that resource originates from Synoptic Data PBC.
