Quality reporting from a Republican congressional candidate from Idaho...who runs a blog called "The Economic Collapse."

8pm advisory holds at 185mph, pressure down to 916mb.

 

I think we reach or surpass 190mph by the 11pm advisory.

Slowly improving by TTSEA.

 

Down to 274 AQ index.

Only topped 86 here. So traded the heat for the smoke today.

Hard to tell for sure... but watching the visible satellite loop it appears that the smoke from the Jolly Mountain fire has shifted from blowing from east to west (which has been pumping smoke into the Seattle area) to now blowing from the SW to NE in the last couple hours.   This should help the situation here in the foothills.

Good for this area.

Can't help but notice all the smoke heading towards Salem and Portland from down south.

Which will also be rotating up through us eventually.

Let's be honest here... someone's political stance has absolutely nothing to do with their opinion on the storm. The whole cat 6 thing wasn't thought up by some republican or democrat or any other politician. As a matter of fact, according to what I've read on this forum, the cat 6 thing was drummed up by amateur meteorologists posting to social media....

 

Little discussion on the cat 6 deal in another part of the forum I lurk around...

True.

 

Into the unhealthy category for you now.

Sun is looking more red as it gets lower in the sky.

Always happy when the air quality improves dramatically to just "Unhealthy".   :)

You're right, I shouldn't have brought politics into it. But you gotta admit it's pretty funny when a politician in Idaho writes up sensational headlines about a hurricane on the East Coast. It's not about to become a Category 6, and it's not about to wipe cities off the map.

This weather station is directly in the path of the eye wall. Let's see how high winds get before the station (most likely) blows away.

Definitely improving here.   It no longer smells like a campfire outside.  

 

Yeah I can't smell smoke anymore. Sun disappeared a bit ago behind some clouds - I think.

Indeed. I agree.

SW winds made it to McMinnville!

What has been up with the consistently high dew points the last couple days? Is that related to the smoke inversion at all? Because at face value we should be in a fairly dry airmass. At least for yesterday and today.

I was going to ask the same thing.

I'm sure it's a product of the inversion that set in yesterday. Air mass never even came close to mixing out dry adiabatic in the valleys.

My preferences can beat up your preferences’ dad.

Yeah that station will end up going down. Anguilla looks like it will be next.

Sustained winds just jumped to near 40kts. Should be gusting over 100kts within 45mins:

Irma's eyewall is only about 20 miles away looking at radar. Once that big rainband moves in, there's gonna be a huge spike in wind.

00Z GFS is not good for Miami... Irma does not travel over land in Cuba and heads right for South Florida.   It has trended a little east of the 12Z run though.    

 

Update... looking dicey for Charleston again on this run.   Running right up the east coast of Florida.
