A geomagnetic storm is set to illuminate the night skies of the Pacific Northwest with the potential appearance of the Northern Lights late Tuesday into early Wednesday. However, overcasting clouds may hinder visibility for residents hoping to catch a glimpse of this celestial display.
According to NOAA’s Space Weather Prediction Center, a G4 (Severe) storm watch will be in effect starting November 12, due to a significant coronal mass ejection (CME). This phenomenon involves an eruption of solar material and magnetic fields from the Sun, which can trigger geomagnetic storms upon reaching Earth.
The CME is anticipated to arrive by mid-day on November 12, with experts noting that its effects depend on the orientation of the embedded magnetic field. Should conditions align, the geomagnetic response could produce observable Northern Lights as far south as northern California.
Officials from the Space Weather Prediction Center have indicated that the intensity of the CME will be better assessed once it reaches a point approximately one million miles from Earth, where solar wind observatories will provide critical data for forecasters to make necessary warnings.
While optimism remains high for a chance to witness the Aurora Borealis, particularly on the west side of the Cascades, cloudy conditions could present a challenge. Observers are advised to remain hopeful, as there is still a possibility for clear skies to allow for optimal viewing of this natural wonder.
This situation is developing, and updates will follow as more information becomes available.
