City staff are preparing for a nor'easter forecasted to bring rain, gusty winds, and storm surge to Portsmouth beginning Friday evening September 25, 2026. While updated forecasts have shown some variability in the track and intensity of this storm, the public should expect rain beginning Friday evening and continuing through Sunday, with rainfall totals ranging anywhere from 2 - 6" inches. 

Coastal and low-lying areas could see flooding due to rain, storm surge, and astronomically high tides.
