Note regarding "Approx. Precipitation / Rain Total"
The "Approx. Precipitation / Rain Total" is calculated in whole based on the last measurement from each hour reported - which is accumulative and reset at the beginning of each hour - ideally. However, some stations reset at the wrong time, such as a few minutes after the hour. We have tried to account for this issue. Most gauges report multiple times per hour. For example, a measurement of precipitation at 8:15am could be 0.04 in. of water - then when a measurement is taken at 8:30am might be 0.06 in. - and at 8:56am might be 0.08 in. So, the accumulative total for that hour would be 0.08 in. - not calculated together to equal 0.18 in. of precipitation. Finally, each hourly total for the day is summed to provide the "Approx. Precipitation / Rain Total" figure.
One other note: if the total is 0, but there was obviously rain - then the instrument is not properly distributing its data from the station. The issue could be temporary or permanent.
