While Hurricane Joaquin is finally starting to move to the northeast, away from the East coast, secondary impacts continue on the Eastern Seaboard. Very heavy rain, inland and coastal flooding, rough seas, beach erosion and rip currents will be a problem through the weekend. In addition, those with shipping interested in the Western Atlantic will be directly impacted for the next few days.
As of 5 pm ET, Joaquin remains a category 4 storm with winds speeds of 150 mph. Joaquin is moving northeast at 17 mph. Joaquin is forecast to remain a major hurricane through Sunday moving on a northeast trajectory. This path brings Joaquin just west of Bermuda Sunday evening.
Even though Joaquin will remain far off the East Coast, impacts will continue up and down the eastern Seaboard through the weekend. Heavy rain will continue across the Carolina’s as moisture from Joaquin interacts with the stationary front along the east coast.
Additional rainfall amounts of 5 to 8 inches of rain is expected across far southern North Carolina and much of South Carolina through Monday morning.
This additional rainfall will further compound the flooding situation as heavy rain has fallen in many of these areas of over the past few days. The 4 day rainfall totals now stand at widespread 3 to 5 inches in the Carolinas with pockets of 8 to 12+ inches. Some of the hardest hit areas are the coastal regions of South Carolina including Charleston as well as southern North Carolina, just south of Wilmington.
With the forecast rainfall and ongoing flooding, Flash, Area Flood Watches and Warnings are in effect across much of the Carolinas as noted in the green shading in the graphic below. In addition, most coastal areas in the Mid Atlantic are experiencing flooding and beach erosion with each high tide. Thus Coastal flood warnings and advisories are in effect from the Carolina’s north to Long Island.
The graphics below highlights the individual coastal gages and river gauges that are experiencing and or forecast to experience flood levels. The orange indicates minor flooding, red moderate flooding and purple is major flooding.
Those with interests along creeks, river and in lower areas along the coast are urged to remain aware for changing water levels.
