The east wind has ramped up in the Gorge this morning; peak gusts are around 75 mph at Corbett and 87 (as of 8am) at Vista House. That’s STRONGER than what we saw Monday when Matt Sloan recorded a 115 mph gust on the steps. Since that time it appears a power outage may have put Vista House out of service. Today is definitely a 100+ day out there. Actually last night was too.
East wind has backed off in most of the metro area this morning but as expected the wind is much stronger in the west end of the Gorge as the flow is channeled through a smaller area. A strengthening inversion is the reason for this. I see observations near Estacada and Sandy around 1,500′ and above are about 10 degrees warmer at 10am compared to yesterday at the same time. Pressure gradient is higher than what we saw Monday too, around 11 millibars from PDX to The Dalles.
Everyone else can enjoy the sunshine and mainly calm wind…oh, and don’t start any fires, there’s a Red Flag Warning for the Cascade foothills. It’s getting real weird out there…
