Churning system to raise surf, downpours along US East Coast

Drenching showers and gusty winds will increase along the mid-Atlantic through midweek as a system brushes the coast.
The main impacts will be locally dangerous surf and rain that slows travel for a while or ruins a day at the beach.
Small craft operators should exercise caution outside of protective inter-coastal waterways as the disturbance kicks up winds and waves.
This system was once referred to as potential Tropical Cyclone 10, but the window for it to develop into a tropical depression or tropical storm has closed.
The tropical disturbance pestered Florida with downpours for nearly a week. Fort Myers, Florida, received 14.1 inches of rain during Aug. 23-28.
The center of the disturbance is currently poorly defined. However, the feature will remain over the warm waters of the Gulf Stream, and a non-tropical system to the north is likely to help generate some spin and increase winds in the region.

Strong winds aloft have helped to prevent the disturbance from developing.
Into Wednesday, a non-tropical system to the north will help add wind along the coast from Virginia to Massachusetts.
These winds may be as punchy as that of a modest nor'easter. Gusts right along the coast will reach between 40 and 50 mph. The wind direction will vary from east to northeast during the storm, then swing into the north and northwest once the storm passes.
The winds will cause seas and surf to build along much of the Atlantic Seaboard. Where the winds blow the strongest, from eastern North Carolina to New Jersey and Long Island, New York, minor beach erosion can occur with minor coastal flooding possible at times of high tide.
The increased wave action will also pose a risk to bathers much of this week. The number and strength of rip currents will be higher than usual. Bathers heed all warnings and only venture into the water where lifeguards are still on duty. Surf conditions may improve from south to north from Wednesday to Friday.
The combination of the disturbance and the non-tropical feature will allow a batch of locally drenching rain to roll northward along the Atlantic Seaboard. In most cases, the rain will last 12-24 hours.
It is possible that enough rain will fall to cause a few incidents of urban flooding that will far pale in comparison to ongoing events in Texas and southwestern Louisiana due to Harvey.
During the latter part of the week, the tropical feature will head out to sea over the North Atlantic. Some additional strengthening may take place several hundred miles southeast of New England and south of Atlantic Canada.
More than 1,000 miles to the southwest, Harvey is beginning to move and will bring drenching rain to the Northeast during part of the Labor Day weekend.
"Elsewhere in the Atlantic, another tropical disturbance, currently near the Cabo Verde Islands, has the potential to develop into a tropical storm late this week," AccuWeather Hurricane Expert Dan Kottlowski said.
This new disturbance may threaten the northern Caribbean islands next week.
The next name on the list of tropical storms for the Atlantic this year is Irma.
