Moderate to Major coastal flooding is LIKELY across the Lower Chesapeake Bay, Lower James and York Rivers, and portions of Hampton Roads and the Eastern Shore, from late Friday evening through Monday. As Sally departs and becomes a low pressure system, attached with a front, strong high pressure will build in across New England, which will produce a persistent Northeast wind Friday night into the weekend. The combination will push water from the Atlantic and Chesapeake Bay into coastal communities.
MODERATE TO MAJOR COASTAL FLOODING:
2 to 3 FEET of water inundation is likely along the Mouth of the Chesapeake Bay into the Hampton area, Mouth of the York River and Yorktown area, Lower James River to include the Jamestown area, and Norfolk area, including the Elizabeth River at Money Point – South Bridge. Water inundation will likely cause many roads near the shore to be under water, and reaching many homes and businesses along the shoreline. Property damage from water inundation is possible.
1 to 2 FEET of water inundation is likely across the Central Chesapeake Bay, Tangier Island, and the Lower Potomac River near Colonial Beach and points southeast.
1 FOOT OR LESS of water inundation is likely inland from these areas, including the Upper portions of the James and Potomac Rivers. Some docks/piers may be underwater, but very minor impacts are expected.
WIND: North winds Friday evening, sustained winds 20 to 25 mph and gusts 30 to 40 mph, will switch to the Northeast by Friday Night through Monday. Winds will be sustained 15 to 25 mph and gusts up to 30 mph. Winds will slowly subside on Monday.
WAVES: Large waves will be likely across the Chesapeake Bay and Coastal Atlantic. Wave heights are expected to range 3 to 6 feet through the weekend along the Chesapeake Bay, with wave heights larger than 8 feet along the Coastal Atlantic.
RIP CURRENTS: There is a HIGH and DANGEROUS rip current risk through the weekend along the Coastal Atlantic. It is recommended to AVOID going out into the water this weekend.
NEVER fight a rip current. Doing so will make you exhausted and pose a higher risk of drowning. If caught in a rip current, swim parallel to the coast. Remember to always stay calm and raise your arm to attract attention. Always conserve your energy as waves can assist you back to the beach. Most importantly, if red flags are posted, stay out of the water — This is for your safety!
