Data about the amount of rainfall recorded during the 36 hours before 9am each day, along with recently recorded hourly and daily rainfall totals and a running annual total, will be displayed. Station searchĮnter the station/rain gauge name into the search box. Clicking on a dot reveals hourly, daily and monthly data of recently recorded rainfall totals, along with the running annual total at that gauge. The colour of the dot indicates the amount of rainfall recorded in the 36 hours before the time indicated in the pop-up information. Moving the cursor over a dot will reveal the gauge name and the amount of recorded rainfall. Map searchĮach dot on the map represents a rain gauge. We can't say exactly how much higher they should be.Select a map point or search for a particular rainfall station to view rainfall data by hour, day or month.ĭata shown is real time rainfall data from SEPA’s automated rain gauges. But remember that it can easily rain twice as much up there as in town, so you should expect higher values over Ripinsky than compared to the 20 events. For this reason, the current rainfall amounts over Ripinsky are highly relevant. So in general, the storm could have been far worse if snow levels were higher and more rain fell over Ripinsky instead of snow. Also, much of the rain that did fall up there above 2500ft was absorbed by the snowpack. In December 2020, most of the precipitation that fell on Ripinsky was in the form of snow. Ripinsky rainfall data and the record precipitation values from 20 (which were measured in town, not on Ripinsky)? This is a tricky one. Can a one-to-one comparison be made between the Mt.All this page can do is provide the raw data and inform you to make your own decisions. Ripinsky, but not so much in town.should I be worried? We don't know how much rain needs to fall on the mountain to cause issues like flooding, landslides, and debris flows/erosion on the slopes below. This is important because in warmer months, the rain that falls over the mountain runs off towards Cathedral View, Piedad, and Lutak, and contributes to groundwater pressure at the base of the mountain. Ripinsky? Steep mountain slopes can easily double or even triple the amount of rain that falls on the mountain, as rising air is lifted over the slopes. Why does it sometimes rain so much more on Mt.If anything, we suspect it should be raining *more* on Riley than on Beach road. Is this because it is raining less on top of Riley than it is on Beach road? We can't answer that question for sure, but we suspect that the gauge on Riley tends to under-report rainfall due to wind effects on top of the mountain. The Mount Riley gauge has consistently reported less precipitation than the other gauges nearby.For this reason, the airport data is not very representative of impactful precipitation in town. Precipitation at the airport is often 20 - 50% less than that recorded in town. Why does it generally rain less at the Airport and at Lutak? These are well known drier microclimates in our area. During times of below-freezing weather, they are the only gauges that offer an accurate view of precipitation.
