*EQUIPMENT CHANGE: Effective October 12 at 0915: Smaller less sensitive Wind Cups replaced the
larger cups on the Anemometer. Readings will show a reduction in the Average Wind Speed and
Total Wind Run during times of intermittent low wind speeds compared to the readings in previous
months and years. High Wind Speed should not have been affected.
