Subtropical Storm Karen, the 11th named storm of 2025, is embedded in a large upper-level low and, as of Friday morning, moving northeast near 9 mph. Over cool waters and facing hostile conditions, it is expected to lose its thunderstorms by early Saturday and be absorbed by a front, posing little danger to land. Meanwhile, a developing East Coast nor’easter could flood coasts from North Carolina to Cape Cod, whip 40–60 mph gusts and build 10–20-foot waves, with a worst-case jump to hurricane force. AccuWeather says the system could be named Lorenzo, though impacts may mirror a powerful nor’easter.
