If you are getting an inaccurate forecast reading we would recommend restarting the display when your local pressure is at 29.92. You would remove the power from the display for about 3-5 minutes. After you power the display back up it will restart the 14-33 day learning mode. During the 14 days while the learning mode icon is on the display you may see some inaccuracies in the pressure and forecasting but once that is complete you should see accurate readings.
I too have experienced problems with the forecasts on my Acurite. Despite going through the 33 day learning period. Also I get a Strom warning regularly despite no storm. I am in the UK so I don't no if that makes a difference. Good luck with customer services I didn't get very far.
