UA!! Got Rain!!

With an El Nino year like this has been, we have almost lost track of the number of fully formed, named hurricanes that have swept close to the Big Island this year -- 13 or 14 and counting.

Last week we watched as "OHO" blew by dropping a ton of rain...we had four inches in four hours.  Then, during the night, Phil got curious and trudged out with umbrella and flashlight to check the rain gauges again.

In the morning we checked again -- 7.2 inches in 24 hours...and only one small puddle!

When we retired from Humboldt County and relocated to the Big Island, we made a thorough investigation of rainfall so we knew what to expect.  Just south of Pahoa, we get approximately 120-140 inches a year.  We continue to be delighted that 80% of that falls during the night.

CLICK to enlarge map.  Beginning at Hilo, and going mauka (toward the mountain) rainfall increases fast--from 100'/year to 300++ in only 15 miles!  Altitude directly affects rainfall,  especially on the East side.
