Tropical depression has 70 percent chance of forming in Atlantic this week

Eyes on a disturbance that could become tropical storm

Circulation associated with the storm is gradually become better defined, even though the associated thunderstorm activity is not, wrote Hurricane Specialist Lixion Avila in a morning update.

A tropical disturbance in the middle of the Atlantic that's been dubbed "Invest 94L" could become the Atlantic's fourth named tropical storm of the year - Don.

The low pressure hasn't moved much, but will likely begin a west-northwest track at 10 to 15 miles per hour Wednesday, officials said.

The Atlantic Hurricane season begins in June and ends in November each year. Some of the lead hurricane forecasters in the world are now calling for an above average season, and said it'll be busier than they originally expected.

WDSU chief meteorologist Margaret Orr said the reason for the updated forecast is because of the warmer Atlantic waters and the likelihood of a non-existent El Nino, which causes strong upper-level winds that can prevent tropical development. However, the cluster of showers and thunderstorms remains disorganized.

Klotzbach and his team are now predicting 15 named storms, eight of which will become hurricanes and three of which will become major hurricanes - or hurricanes that are Category 3, 4 or 5.

Forecasters are giving the system a 70 percent chance of forming by Friday.

"With the increase in our forecast, the probability for major hurricanes making landfall along the United States coastline and in the Caribbean has increased as well", Klotzbach's report stated.
