Hurricane season officially begins June 1, but a tropical storm does occasionally form before then, including the past three hurricane seasons.
Forecasters expect Suptropical Storm Alberto to move into the Gulf and toward the Gulf Coast this weekend.
Parts of Florida, Georgia, Alabama, Mississippi and Louisiana have already seen heavy rain this week, and further deluges could leave those areas vulnerable to flash flooding and river flooding. Heavy rainfall is expected from western Cuba to Florida an through the northeast Gulf Coast through the weekend. A ridge of high pressure will build in from the southwest, producing the hottest weather of the year so far. It still remains an unorganized mess as it meanders off Mexico's Yucatán Peninsula but is expected to churn northward into the Gulf of Mexico and approach Florida this weekend.
Development looks to take place either late Friday or early Saturday, Hurricane Hunters are expected to fly into the storm Friday afternoon and providing valuable data which will help with the forecast.
"There is a chance that Alberto could be a hurricane before it makes landfall", said Andrew Kennedy, a National Weather Service meteorologist in Jacksonville.More news: Best and worst times to hit the road this Memorial Day weekend
The system is now near the Yucatan Peninsula but could develop in the Southern Gulf by Saturday, ABC News reports. A storm of this type is not unusual for this time period and region. "But we are fairly, highly confident that the main impact is going to be heavy rain, and it could bring enough rains to cause flooding problems".
The NHC predicts that Alberto could reach tropical storm status overnight, although it's too early to predict where that could occur and what magnitude the storm system might achieve.
"The usual low-lying areas will flood", DeCarlo said.
When you break it all down, get ready for more rain over the next seven to ten days.
Forecasters from the US-based National Hurricane Center (NHC) have said there is a 90% chance tropical storm Alberto will develop the within the next five days.
