5 Significant and widespread inundation is occurring along the lower Tidal Potomac and adjacent tidal tributaries. Numerous roads and structures are affected.
3.5 Water covers roads on St. Georges Island, is in yards, and approaching structures. To the east, inundation is occurring at multiple marinas off St. Mary's River, Smith Creek, and Jutland Creek.
3 Yards are flooded on Saint George Island, and water will begin covering the road leading to the island, especially if there is wave action.
2.7 Water begins to go over a portion of the bulkhead near the Straits Point bridge, and also covers yards in the St Georges Creek and St Marys River areas.
