Daily And Monthly Rainfall Totals

[Abby_wx]

With yesterday's rainfall I managed to add about 8 mm. That brings me to 42.5 mm, or basically normal. There is still a large deficit when looking at the last three months.

I'm at 52.3 mm for July.

With only 439.4 mm, the period January-August in YVR is the 9th driest of all time [rain only].

Record is 363.4 mm in 1949, then 389.1 mm in 1985.

You are throwing out some big winter analogs there. 1949-50. 1985-86. Legendary stuff

The records you show are lower than than the 439.4 mm. So is 439.4 mm a new record? Or did I misunderstand something?

Record low. 2019 is the 9th driest year so far.

Wow, I had no idea it was this dry year to date! It feels so wet here in the interior this year, but I am so wrong that I guess it's appropriate to quote Ben Shapiro now: "Facts don't care about my feelings."

Same here relative to average... this year has only felt wet due to the persistent cloud cover.

Most of the traditionally wet months have been below average here. Only April and September have been above average. July was near average. All others were below average.

112.2 mm here in September so far.

I looked at YXX... they're at 723.8 mm for the year to date. The average for the year is 1537.8 mm, meaning they need 814 mm to catch up to average. The average for Oct-Nov-Dec is 565.1 mm.

Another interesting tidbit: we've been getting drier over the years. The 1971-2000 climate normals showed 1573.2 mm for the annual precipitation at YXX, compared to 1537.8 mm for the 1981-2000 normals. That's a drop of 35.4 mm or 2.25% over 10 years.

24.2 mm of the difference can be attributed to lower rainfall, but the remaining 11.2 mm is due to lower snowfall. Average annual snowfall declined by 8.3 cm over 10 years.

The warm season months; June, July, August and September, have all seen declines in precipitation. December and February have both seen substantial declines (-22.0 mm and -28.0 mm, respectively). Other months, such as January, October and November have seen modest increases.

Pick any random weather station in BC and you'll find that precipitation peaked in the 1990s. Here is one random example...

Buried deep, deep in the Environment Canada's website is this graph. How population has grown by 5 times with 10 times the number of tax payers (largely because women work too), and yet we can't afford to maintain 1/4 the number of weather stations.

Sherriff Goofs will get right on it, it should be an election issue to fix.

I'm at 164.8 mm for the month.

I'm at 164.8 mm for the month.

With last night's rain, I'm just under 140 mm for the month (have to check the manual gauge for the exact total).

Crazy... that's the opposite of the direction we need to be going. A major aspect of climate change is increasing or decreasing precipitation (not debating the cause, just acknowledging that the climate is changing). You'd think that such information would be valuable for planning agriculture and flood prevention.
