A powerful offshore nor’easter is churning up the eastern seaboard, bringing coastal flooding, beach erosion, and gusty winds to Maryland through the weekend of September 27, 2026. While the storm will stay safely off the coastline, its massive size and intensity are driving coastal flood warnings from Anne Arundel County down to the Chesapeake Bay and Ocean City, according to local forecasts.
Coastal Flooding and High Tide Warnings in Maryland
Coastal flood warnings are currently in effect for Anne Arundel County during high tide cycles, where moderate coastal flooding is expected. Forecasters project up to one foot of water above dry ground during early morning high tides on Thursday and Friday. Additional coastal flood warnings cover central and southern Chesapeake Bay areas, Ocean City’s back bays, and the Ocean City inlet, with high-water conditions expected to persist through at least Saturday night.
Along the Atlantic coast, beaches from Assateague Island northward to the Delaware line face a long duration of large waves and persistent beach erosion. In Ocean City, sustained winds gusting between 30 and 40 miles per hour forced organizers to cancel the opening day of the Oceans Calling Festival. WBAL-TV meteorologist Ava Marie noted that severe beach erosion and high winds made it impossible to safely finish assembling stages and tents for the Friday lineup.
Weekend Weather Impacts for Baltimore and Inland Areas
While inland locations across Maryland remain mostly dry, coastal neighborhoods will experience occasional showers through the weekend. Central Maryland and the Baltimore metropolitan area face a low chance of wet weather, with afternoon temperatures holding in the upper 60s and 70s. However, computer model guidance suggests the nor’easter could take a slightly closer track to the coast, which might push rain bands westward over the state on Saturday or Sunday.
A gusty northerly wind will prevail throughout the weekend. Meteorologists indicate that this northerly direction will help pull water out of the Chesapeake Bay, alleviating some coastal flood concerns as the storm progresses. If the system tracks slightly farther east, rain showers will become less likely across central Maryland, leaving the region with breezy and cool conditions rather than a washout.
Power Outage Preparations and Next Week Forecast
Strong winds associated with the offshore system carry the potential to knock down tree limbs onto power lines and electrical equipment. Baltimore Gas and Electric advises residents to monitor local outage maps and report downed lines immediately. Officials remind the public never to approach fallen overhead power lines.
Conditions are expected to improve early next week as the system moves away. A warm-up will bring dry weather through Wednesday, with daytime temperatures climbing back into the middle to upper 70s and near 80 degrees ahead of an approaching cold front on Thursday or Friday.
