Donít put your umbrella and raincoat away just yet ó youíre going to need them.

The storms that have pounded the Tampa Bay area over the past several days are expected to continue Friday and throughout the weekend ó and even into the start of next week.

The wet weekend can be chalked up to increased moisture thatís lingering and stretching east. Thereís a 50 percent chance of thundershowers starting Friday afternoon.

Those looking to spend Labor Day weekend outside should expect afternoon showers to start at about noon Saturday, said National Weather Service meteorologist Tony Hurt.

A deep southeast flow is what has meteorologists forecasting downpours, gusty winds and frequent lightning as it moves across the area.

Almost three inches of rain fell Tuesday and Wednesday, according to the gauge at Tampa International Airport. The total rainfall for the year is at 33.23 inches ó almost half of that rain coming in August.

Another complication is the tropical wave lingering in the Caribbean, which the National Hurricane Center said has less than a 10 percent chance of developing into a tropical system.

It could still affect the bay area, meteorologists said. Depending on its track, the wave could bring some extra rain to the region by Tuesday.

Itís not abnormal to see the wave at this time of year, especially as we enter the peak of what has been a quiet hurricane season so far. However, the weather service doesnít believe the tropical wave poses a threat to the region because itís so disorganized.

Itís expected to dissipate somewhere west of the Gulf of Mexico.

"We get tropical waves that move through quite frequently," said meteorologist Rodney Wynn. "The National Hurricane Center isnít looking at it for any kind of development."

The situation is far different off the coast of Africa, where a tropical cyclone is expected to develop within the next 24 hours near the Cabo Verde Islands. The islands could experience up to eight inches of rain and life-threatening flash floods from whatís known as Tropical Cyclone Six, forecasters said.

The cyclone is then forecast to gradually turn to the west-northwest while passing near the southern islands of Cabo Verde on Friday, when it could strengthen into Tropical Storm Florence, according to the hurricane center.

If the tropical storm forms, it would become the sixth named storm of the Atlantic season.
