Rainfall Update ~ April 2017

Has 2016-17 Been Our Wettest Water Year? The remarkable rain year continued through April!  The monitoring stations in the Napa County ALERT Rainfall Monitoring System added between 3 – 6 inches to annual rainfall totals, not quite double the long-term average for the month of April.  At the City of Napa Corp Yard, 46.06 inches have now been recorded for Water Year (WY) 2016-17.  Due to malfunctioning equipment, data are not currently available for the other extreme of the watershed, Mt. St. Helena, where we receive the most rainfall; however, the gauge that frequently gets the second-most rainfall, Mt. Veeder, has recorded 83.87 inches this year!  On average, the 17 rain gauges in the Valley indicate that we’ve received 179% of mean annual precipitation, further bolstering this water year’s position as the wettest in the 16-year ALERT System’s historical record. We are currently experiencing an early heat wave in the beginning of May and it seems like the historic rainy season has come to an end, but the historical record tells us that we commonly receive only 95% of our rainfall by the end of April, with 3% falling during May.  In the City of Napa area, the month of May has only been completely dry in 5 of the past 30 years.  So, this means there may be even a little more rain to come! The Napa State Hospital rain gauge has now logged 44.09 inches of rainfall, placing WY 2016-17 at the third wettest year since record keeping began in 1893.  In the number one spot is WY 1982-83 with a recorded total of 50.19 inches.  – Paul Blank, Senior...

Rainfall Update ~ March 2017

It rained, it poured… As of the end of March, the monitoring stations in the Napa County ALERT Rainfall Monitoring System have recorded rainfall totals between 42.74 inches (City of Napa) and 93.06 inches (Mt. St. Helena).  On average, the totals of the 17 rain gauges in the Valley indicate that we’ve received 167% of mean annual precipitation.  Water Year (WY) 2016-17 has now surpassed WY 2005-06 as the wettest in the 16-year ALERT System historical record. As reported in Berry Eberling’s recent Napa Register article, Napa Valley rainfall records are commonly based on the Napa State Hospital rain gauge, which has operated near continuously since 1893.  At this gauge, 40.55 inches of rain have been logged through March making WY 2016-17 so far the seventh wettest in the long-term record.  In the number one spot is WY 1982-83 with a recorded total of 50.19 inches. – Paul Blank, Senior Hydrologist,

Rainfall Update – January 2017

How are we doing so far this Water Year? The Napa County Rainfall and Stream Monitoring System, also called the ALERT System, is a network of automated rain and stream gauges installed throughout the County that provides advanced warning of potential flooding.  Although flood warnings are the primary purpose of the ALERT System, data records from the 17 rain gauges can be assessed to better understand current water conditions in the Valley. Rainfall is measured as a depth, in inches, and rainfall depths vary by location.  So far, rainfall totals for Water Year (WY) 2016-17, from October 1 through January 31, range from ~ 26 inches in the eastern hills at the south end of the Valley to 51.53 inches on Mt. St. Helena.  In order to assess rainfall across the whole Valley, we compare the total for each gauge to the annual average for that specific gauge.  Even though Mt. St. Helena has received twice as much rain so far this year than the southern end of the Valley, both locations are between 105% and 110% of average.  Altogether, the 17 ALERT rain gauges indicate that so far the Napa Valley as a whole has received 110% of its average precipitation for the year. – Paul Blank, Senior Hydrologist,
