Drought continues with fear of fire throughout Western Washington

Severe drought is settling in across most of Western Washington — including Kitsap County — where dry conditions raise the risks of wildfire, and low streamflows could impair salmon spawning this fall.

Western Washington is one of the few places in the country with “severe” drought.

Scattered showers and drizzle the past few days have done little to reverse a drying trend as we go into what is normally the driest period of the year, from now through August. As of today, the fire danger is moderate, but warmer weather could increase the risk substantially within a day or two.

The topsy-turvy weather that I observed across the Kitsap Peninsula last quarter (Water Ways, April 2) continued through June. Normally, the southwest corner of the peninsula near Holly receives twice the precipitation as the north end near Hansville. But that didn’t happen last month, when the monthly rainfall total was 0.61 inches in Holly and 0.83 inches in Hansville. Silverdale, about halfway between, received 1.11 inches in June.

Kitsap weather shifts to unusual patterns over past three months

“Average, very average.” That’s how things were going for the first quarter of Water Year 2019, which began in October and ran through the end of last year (Water Ways, Jan. 4). But the second quarter, which began in January, presented an uncharacteristic upheaval, as various portions of the Kitsap Peninsula went their own way.

We’ve talked before about how Southwest Kitsap typically has twice the rainfall as North Kitsap. But even the patterns of rainfall have been different the past three months, and you can’t compare these areas to anywhere else. Let’s take them one at a time:

Hansville: Representing the north end of the peninsula, Hansville received 2.5 inches of precipitation in January, well below the 4.4-inch average for the month. February followed with a little below average, 2.8 compared to 3.2 inches. Like January, March was quite low, with 1.1 inches compared to a 3.5-inch average. In the first chart (click to enlarge), you can see this water year’s rainfall total (blue line) slipping below average (pink line).

The word is ‘average’ for the first three months of Water Year 2019

Average, very average. That was my first reaction as I looked over the rainfall data for the first quarter of Water Year 2019, which began Oct. 1.

The point was driven home when I looked at the rainfall totals for Silverdale on the website of the Kitsap Public Utility District. October’s rainfall total was 3.23 inches, compared to a median average of 3.74 inches. November’s total was 5.51, compared to a 6.83 average. And December’s total was 9.31, lining up perfectly with a 9.31 average. (Exactly the same! What’s the chance of that happening?)

Ongoing lack of rainfall raises concerns for chum, coho salmon

We’ve just gone through one of the driest five-month periods on record in Kitsap County, yet the total precipitation for entire water year was fairly close to average.

Water year 2018, which ended Sunday, offers a superb example of the extreme differences in precipitation from one part of the Kitsap Peninsula to another:

  • In Hansville — at the north end of the peninsula — the total rainfall for the year reached 35.2 inches, about 3.5 inches above average.
  • In Silverdale — about midway from north to south — the total rainfall was recorded as 43.1 inches, about 5 inches below average.
  • In Holly — near the south end — the total rainfall came in at 82 inches, about 3.3 inches above average.

The graphs of precipitation for the three areas show how this year’s rainfall tracked with the average rainfall through the entire year. The orange line depicts accumulated rainfall for water year 2018, while the pink line represents the average. Click on the images to enlarge and get a better view.

Amusing Monday: Words cannot dampen the essence of rain and snow

After I woke up one morning last week, I noticed that there was a thin layer of water coating the outdoor furniture and concrete around our house. I stepped outside and felt a fine mist in the air. I wondered, could this be the “scattered showers” that weather forecasters had talked about?

Surely, a “mist” is different from “showers,” which is also different from “rain.” But where does one end and another begin according to the experts? A little help from the glossary of the American Meteorological Society revealed that the proper term for a very light precipitation is “drizzle.”

My curiosity got the better of me, and I found myself going deeper and deeper into the terminology for precipitation, both official and unofficial, first in English and then in other languages.
