A cloud of smoke unfold over the lowlands of western Washington final evening as fireworks returned to the area.
The outcome was a profound degradation in air high quality, paying homage to the consequences of wildfire smoke intrusions of previous summers.
Contemplate the air high quality round Seattle from the EPA AirNow community for the central Puget Sound space. Air high quality was fairly good yesterday afternoon, however went quickly downhill round 10 PM, declining to unhealthy ranges (purple colour) by 11 PM. You understand what occurred round 10 PM.
The determine under from the PurpleAir air high quality community round 10 AM exhibits that the air high quality this morning was nonetheless poor for delicate teams, with some locations within the south Sound being unhealthy for all. Air high quality declines in the direction of the east and south, reflecting the northwesterly winds this morning.
The smoke and poor high quality resulted from the huge return of fireworks to our area, each official and personal.
The smoky haze, abetted by some fog formation, was very evident within the lowlands this morning (see Seattle PanoCam picture under round 9AM)
However if you wish to see some smoke pictures that may shock you, take a look at the SeattlePanoCam pictures final evening.
Right here is a picture at 10:40 PM….you’ll be able to even see a few of the fireworks! Fairly a smoke plume blowing to the south…. I fear for folk dwelling within the downtown highrises!
And the smoke continued southward, well past downtown.
The excellent news is that our air high quality will enhance as we speak, notably after floor warming enhances vertical mixing.
