Station ID 5447 - Tzouhalem-Maple Bay Weather
For some unknown reasons, the sea level pressure of my WeatherFlow station has dropped from 1012.1 hPa (at 21:35 PST on December 7, 2019) to 435.1 hPa (at 21:40 PST on December 7, 2019) - the pressure has remained in the four hundreds since then.
Other than replacing the SPA on the SKY unit, nothing was done to the AIR unit (it was not touched, it was not moved, no settings were changed).
What could have caused this sudden drop of pressure in the WeatherFlow weather station - there has not be any major drop of the pressure on my Davis Instruments Vantage Pro2 weather station.
Any suggestion on options to try (I have contacted WeatherFlow support earlier but I have not received a reply yet).
