Quick answer

Yes, but the United States setup is more selective than Canada tonight. AuroraMe currently lists Akhiok at 28%, Old Harbor at 26%, Bellingham at 25%, Coeur dAlene and Spokane at 22%, Seldovia at 21%, and Yakima at 20%. Treat this as a watch: go only if skies are clear and you have a dark northern horizon.

Prioritize Alaska and the northern inland Northwest. In Washington and Idaho, get outside city glow and look for a clean northern horizon.

Why this alert is selective

Kp 6.7 reaches some US city thresholds, but not everywhere

A Kp 6.7 forecast can push aurora into northern US latitudes, but tonight the stronger city probabilities remain limited. Alaska has the best listed odds, while Bellingham, Coeur dAlene, Spokane and Yakima are watch targets.

This is not a blanket United States forecast. Use the city list as a practical filter, then check live clouds and local darkness before making a long drive.

What to do

A simple plan for tonight

1

Check your exact city forecast before leaving, because a 20-28% city probability still needs clear skies.

2

Avoid streetlights and look north. A faint aurora can be easy to miss from inside town.

3

Use phone night mode or a short camera exposure to detect faint green or red glow near the horizon.
