Tropical storm expected off mid-Atlantic this week

Update 5 p.m.: The National Hurricane Center expects tropical depression eight to become a tropical storm in the next day or two as it moves west toward the Carolinas.

Forecasters are holding off on issuing tropical storm watches, but any intensification may trigger those later tonight.

Labor Day revelers in South Carolina and the Outer Banks may want to be wary of a newly-formed tropical depression, which was just alerted by the National Hurricane Center.

In a special 10:15 a.m. outlook, forecasters said advisories on tropical depression 8 will begin at 11 a.m. Satellite images are showing a closed circulation, and the hurricane center is giving it a 100 percent chance of development over the next two days.

If it gains tropical storm strength, it will be named Hermine. A tropical storm watch may be issued later today, according to the hurricane center.

The depression, which is about 250 miles west of Bermuda, could end up being steered north out into the open ocean.

But AccuWeather forecasters said that doesn’t mean heavy rains from Hilton Head to Nags Head won’t ruin Labor Day vacations.

The storm is moving west at about 9 mph. On this forecast track the center of the cyclone will pass offshore of the Outer Banks of North Carolina on Tuesday.

Unlike dawdling 99-L, which has had South Florida on alert for more than a week, tropical depression 8 formed up quickly after being identified as an area of interest Friday.

An Air Force Reserve Hurricane Hunter is scheduled to investigate the system this afternoon, but initial wind estimates are 35 mph with a minimum central pressure of 1009 mb.

Forecasters don’t think the remnants of Tropical Storm Fiona are having any affect on tropical depression 8, which is why they labeled 8 as a new tropical cyclone instead of a reformation of Fiona.

Tropical depression 8 spins off the coast of the Outer Banks.

For South Florida, rripcurrentain chances have been reduced to near normal amounts through Wednesday, but lifeguards will be on alert for rip currents as increasing east winds whip up the waves rolling onto Palm Beach County’s coastline.

The National Weather Service in Miami has issued a high risk of rip currents through Monday.

Despite Invest 99-L’s glancing blow to South Florida, the National Hurricane Center has increased the chances of it forming into a tropical cyclone to 60 percent over the next five days as it enters the Gulf of Mexico.

It’s been a real  roller coaster ride for the clutch of thunderstorms and showers, which at one point had some forecasters thinking it would spin into a hurricane hitting South Florida.

The National Hurricane Center is now tracking three systems in the Atlantic basin with medium chances to become tropical cyclones, and Hurricane Gaston, which is no threat to land at this point.
