Forecasters closely monitoring tropical disturbance off Atlantic coast

A cluster of showers and thunderstorms off the southern Atlantic Seaboard may become the basin's next tropical depression or storm this week.

The area of disturbed weather, dubbed Invest 98L by the National Hurricane Center, wandered over the Florida Peninsula on Saturday and brought localized downpours to eastern parts of the state.

The center of this disturbance has since moved off the Southeast coast into a more conducive environment for organization.

"As 98L begins to move northeastward away from Florida, conditions should be conducive for further development and organization of this system over the next few days as it moves through a zone of warm water and fairly low wind shear," AccuWeather Senior Meteorologist Dan Pydynowski said.

The next tropical storm in the basin will acquire the name Erin.

A non-tropical system moving into the Eastern states into the middle of the week is expected to largely protect the Atlantic coast states from direct impacts from this brewing tropical system.

"The center of 98L will remain offshore of Georgia and the Carolinas this week as it begins to accelerate northeastward later this week," Pydynowski said.

Invest 98L has been designated a <1 on the AccuWeather RealImpactâ„¢ Scale for Hurricanes.

In comparison to the Saffir-Simpson scale, which has been used by meteorologists for decades and classifies storms by wind speed only, the AccuWeather RealImpactâ„¢ Scale for Hurricanes is based on a broad range of important factors. The scale covers not only wind speed, but flooding rain, storm surge and economic damage and loss.

Rough surf and strong rip currents are likely along the beaches of the Carolinas to the Delmarva Peninsula and New Jersey, as the tropical disturbance swirls offshore into Tuesday. An area of high pressure directing a wind off the ocean to part of the Atlantic coast will also contribute to the enhanced surf.

Operators of small craft are urged to use caution.

Choppy seas are likely to extend northward to part of the New England coast and Canadian Maritimes as this system accelerates northeastward during the middle and latter part of the week.

Cruise and shipping interests should monitor the path of this system and alter course as necessary.

It is possible that this system tracks close enough to the New England coast to bring a period of gusty winds and localized downpours around the middle of the week.

Nova Scotia and Newfoundland will then be next in line to endure locally heavy rainfall and strong winds during the second half of the week.

Elsewhere in the Atlantic, strengthening Tropical Storm Dorian is expected to pass over the Lesser Antilles early this week with strong winds and flooding rainfall.

While it is too early to determine Dorian's exact track beyond the eastern Caribbean, all interests along the Southeast coast should closely monitor this storm heading into Labor Day weekend.
