Data errors

There are a few reasons why this might be happening. One could be a planned or unplanned outage with a particular radar station. See ECCC's outages and maintenance webpage. For US radar stations you can check the status here.

If you are experiencing the data error with more than one station and other people or apps are not, please try clearing your browser cache.
