When a station suddenly disappears from our site, it is because they have not sent us a data report for over 24 hours. We removed all data over 24 hours old from our site to avoid providing outdated information. When possible we provide data from the next closest reporting station that is currently active. The original station will return to our site when they begin to send data again.
These outages are usually due to communications or equipment failures at the weather station where the data is taken, and the outage can last from a few days to weeks.
