Excessive heat warnings, red flag warnings for wildfire conditions, and monthly temperature records being shattered yet again.

This historic heatwave continues, with temperatures made at least 5× more likely by human-caused climate change today.

As I keep saying, this is easily one of the most anomalous out-of-season heatwaves that I’ve observed. It’s also remarkably large in the extent of area impacted by the record heat.

Its impacts will be far-reaching after an already historic snow drought this winter. Without a pattern change, water concerns will then amplify this summer.

@ZLabe I’ve been through three day heatwaves here in SF but this 5 day was an anomaly.
@ZLabe I saw a toot earlier today from @petergleick that a California irrigation district had been forced to start releasing water two weeks early because of the heat.

@ZLabe We're breaking "since accurate records" records by multiple degrees here in BC, Canada:

In the Salmon Arm area, the temperature of 20 C broke a 112-year-old record, with the previous daily high temperature of 16.7 C recorded in 1914.
The mercury hit 22 C in Penticton, where the last record of 17.8 C was set in 1928.

and we "only" had 130mm of rain, instead of the expected 250mm.

B.C. River Forecast Centre says rivers receding after days of heavy rain

Atmospheric river weather system prompted state of local emergency in Fraser Valley

The Globe and Mail
@ZLabe 61F just before dawn. 17% humidity. Fire risk was mentioned on the news this am. 🤔

@ZLabe 109F today.

No mention of fire danger on our local “news”.

We drove into our mountains to escape our “cave” and in my considered opinion our fire danger is extreme+++. One spark and 1/2 of AZ is burnt toast.

I can just imagine what Colorado is like.

@kplklink Wow that is very surprising to hear!

@ZLabe

The duff in the canyon (4600’+/-) was deep and very very dry, weeds were dry and very dense but easily uprooted.

No further evidence of seasonal runoff (dried up recently).

Interestingly some older white oaks were sprouting nicely. Lots of recently dead old alligator junipers. Younger white oaks are largely dead. Sycamore’s are leafed but small.

Q: Is anyone reporting on Svalbard proper this season? I need a bellwether…

@kplklink Thank you for this report out!

@ZLabe I was in the Sacramento Mountains (Cloudcroft, NM) two weeks ago for #wildfire work and was so sketched out I signed up for emergency alerts for my three nights in town. I used to live in NM, so accustomed to *dry,* but this was different.

Today, I drove over Donner Pass for the #WUI Conference in #Reno, and was shocked at the lack of snow. I knew it was bad, but seeing it was wild. I grew up near here (Plumas County) and know what March is supposed to look like.

@n8dly Ugh! Thanks for the report
@ZLabe This is the coolest March for the rest of your life.
