Rainfall Update ~ November 2017

What does Water Year 2017-18 looks like so far? Annual rainfall totals measured last year (Water Year 2016-17) at the Napa County ALERT rain monitoring stations were the highest in the system’s history, as opposed to Water Year 2006-07 being the lowest.  Totals between 44 -100 inches of rainfall were recorded, compared to averages between 25 -52 inches for the stations.  These amounts equate to approximately 180% of mean annual precipitation.  Long-term rainfall data reveal that it was the third wettest year in the 114-year record for the Napa area, right behind the 1981-82 and 1982-83 water years. October 1, 2017 marked the start of Water Year 2017-18, and so far, rainfall totals recorded at the stations range between 3.33 inches (Lake Hennessey) and 7.14 inches (Mt. Veeder), approximately 14% of mean annual rainfall.  On average, the Napa Valley receives approximately 5% of its annual rain during the month of October, and 10% during November.  We had a dry October this year, receiving only 0.7% of mean annual rainfall; however, November was above average at 13.6%. Overall, totals are only slightly below average for the year. – Paul Blank, Senior Hydrologist,...

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,
