This is not to fault the site creator(s) at all, but wow this a good example of how using third party viz libraries can be misleading. At default zoom on my device, this shows the all-time high near Portland, OR (Vancouver, WA) registered 330 days ago, while the nearest visible data for Seattle shows 40 years(!) despite the fact that Seattle’s all-time record was broken the same day. I have to zoom in knowing that fact to get accurate data. Limiting data points on a zoomable map is a great reasonable default, but it degrades pretty terribly when it matters.
