That puts us at 9.61" for the month (it's only the 12th!) and 80" YTD. We're making a run for 100"! The longer Snoqualmie River looks it will be about half of the predicted flow from 24 hours ago: NOW: YESTERDAY: I wonder what Even the current predicted peak flow seems way off, I wonder what went wrong? Their probability graph did way better, where yesterday afternoon it said the most likely range of peak flow would be between ~20,000 cfs and ~42,000 cfs. Here is the max it predicts as of 7:30 AM: Seems more reasonable. It doesn't seem like either is concerned about flooding for early next week. This event was drawn out with pulses of rain rather than continuous heavy rain. Makes a big difference. We can get 2 inches a day forever and never have flooding issues on the Snoqualmie. Also there was very little snow in the mountains to add to the flow. Those extreme flow predictions never made sense to me given the situation. 3 Quote **REPORTED CONDITIONS AND ANOMALIES ARE NOT MEANT TO IMPLY ANYTHING ON A REGIONAL LEVEL UNLESS SPECIFICALLY STATED** Link to comment Share on other sites More sharing options...

Could it mean we finally dry out for longer than 12 hours? Gotta be too good to be true. Not trusting the maps, even the trusty EPS. It will find a way to continue to rain for eternity. That ridge will probably retrograde into the GOA next month, marking the inception of winter in the West. Degree of amplification still questionable though. Could be a close call. Keep the vortex out of Alaska and I think it’ll work. 1 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

TT-SEA Posted November 12, 2021 Report Share Posted November 12, 2021 2 minutes ago, 1000'NorthBend said: Right, but then why was it forecast that way? Were they anticipating more continuous heavy rain but that didn't end up happening? Seems like the rain forecasts weren't showing that and they knew how much mountain snow we had. Maybe the river forecasts are often quite wrong and I just haven't been paying enough attention. Not sure... if we got 5 inches in 12 hours then it would have been bad. But 5 inches over 2 days with pulses of rain and lighter rain in between is typically not going to be a problem unless there massive snow melt involved. 1 Quote **REPORTED CONDITIONS AND ANOMALIES ARE NOT MEANT TO IMPLY ANYTHING ON A REGIONAL LEVEL UNLESS SPECIFICALLY STATED** Link to comment Share on other sites More sharing options...

Phil Posted November 12, 2021 Report Share Posted November 12, 2021 29 minutes ago, 1000'NorthBend said: The most annoying thing about my Ambient Weather Station is how it calculates the rainfall rate. At the start of every hour it resets the rainfall rate to 0.00 in/hour and then it just ticks up as rain falls, eventually resetting at 0.00 in/hour at the start of the next hour. So if we get 0.25" between 1:00 and 1:15 and then 0.01" between 1:15 and 2:00, the rainfall rate at 1:59 (even though it's basically dry) is displayed as 0.26 in/hour. Pointless. It seems like instead it should be taking the rainfall amount from the most recent 1 minute and multiply it by 60 to get in/hour. You can’t switch to the alternative rain rate?
