Or is it just a monsoon season? When the National Weather Service publishes graphs like the one below, it makes me wonder about the quality and site of their Flagstaff equipment. In reality, I think this is just the character of monsoon seasons.

Flagstaff Airport is just below normal for the season. A few sites in Northern Arizona, like Walnut Canyon, are well above normal. As I have mentioned in the past, I report my rainfall totals to two sites. The University of Arizona operates Rainlog. NOAA runs CoCoRaHS . Rainlog is easier for most people to use because of the required resolution is lower than CoCoRaHS. Also, I like Rainlog’s map feature.

Here is a map of the Flagstaff area with rainfall totals from 6-15-2012 until 8-17-2012 from Rainlog. At least one site appears to have not been reporting all summer. It is right next to my site, on the map. Others may have missed data, but by and large, the people who record their data are diligent about it.

Many locations have reported 5 inches or more. I have reported almost 6 inches in the middle of town. There is string of stations from Kachina Village up to University Heights, including the Airport, which are around 3.5 inches. This is just how monsoons go. The Rainlog map is fun. You can look around Northern Arizona and see how the rest of the state is doing.

It could all change with the next storm. If you want to know what is happening in your neighborhood, you can buy an official CoCoRaHS rain gauge and report your precipitation to both websites. Rainlog also sells a rain gauge, but I am not sure if the resolution is high enough for the CoCoRaHS standard.
