NAPPI’S NOTES

Nor’easter: dangerous surf Friday, coastal wind this weekend

Thursday stays mostly dry. Dangerous surf and rip currents build Friday. Northeast wind could gust over 35 mph for more than two days along the southern Maine coast, with the strongest winds Sunday. Rain may linger into Monday, but Maine’s totals still depend on the storm’s loop; the strongest heavy-rain signal remains over southern New England. Watch for splashover and avoid rocks, jetties and seawalls. Open More → Nor’easter Center for updates, and Premium for my detailed Maine forecast.

Translating Kp and the solar wind into a practical Northern Lights outlook.

KP INDEX · 0–9—LOADINGGlobal geomagnetic activity. Kp 5 begins a NOAA G1 storm. BZ · MAGNETIC FIELD—Direction · nTNegative (southward) is favorable because it helps solar energy enter Earth’s magnetic field. SOLAR-WIND DENSITY—particles / cm³More particles can add intensity, but density alone does not predict visibility.

This latitude-based guide is approximate, not a guarantee. Earth’s magnetic geography and the aurora oval vary; confirm on NOAA’s live map. Darkness, clear skies and low light pollution are still required.
