NAPPI’S NOTES

Nor’easter’s Maine impact day: rain bands and dangerous surf

Monday is Maine’s main impact day. The weakening nor’easter is south of Long Island this morning and will move toward the Gulf of Maine tonight. Rain brings welcome relief where bands set up, while the shoreline remains the sharpest safety concern.

• Coast: High Surf Advisories continue until 6 p.m. from York County through the Midcoast, with 7–12-foot breaking waves and a high risk of rip currents. York County has a Coastal Flood Statement from noon to 3 p.m. for possible splashover and water in the most flood-prone spots near high tide. Stay off rocks, jetties and seawalls.

• Wind: Raw northeast gusts near 25–30 mph at the coast gradually ease tonight. Rough seas and Small Craft Advisory conditions linger on many waters into Tuesday.

• Rain: On-and-off rain continues through this evening, locally heavy in narrow bands. Bangor to Bar Harbor is forecast around 1–1.5 inches for the storm, with far less in northern Maine. This helps dry ground where it falls but does not end the drought.

Remaining showers end early Tuesday, with gradual improvement as the storm pulls away.

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.
