Tropical Storm Danielle formed Thursday in the central Atlantic, just one day after August came and went without a named storm for only the third time since 1961, and it’s expected to become a hurricane this week, according to the National Hurricane Center.
Danielle formed from Tropical Depression Five near the Azores. It was moving east Thursday morning at 2 mph about 960 miles west of the Azores, with maximum sustained winds of 40 mph.
Another system near the Caribbean is gradually developing but is expected to remain outside of the Caribbean Sea as it moves generally toward the U.S. East Coast. Forecasters said though the environmental conditions are marginally favorable for development, the system only needs to slightly develop over the next few days in order to become a tropical depression.
As of 8 a.m. Thursday, National Hurricane Center forecasters said it has a 60% chance of developing in the next two days and an 80% chance over the next five days.
The presence of wind shear near the Caribbean could be a hinderance to further development beyond a tropical depression, according to AccuWeather, the private forecasting service.
A third system moved off the coast of Africa and has a moderate chance of strengthening into a tropical depression as it gets further into the central Atlantic, but if it develops, it also will be short-lived, the center’s 8 a.m. update said, as conditions later in the week will be unfavorable for development.
There have only been three other named storms so far this season — Alex, Bonnie and Colin — with the last one, Colin, dissipating on July 3, meaning this 60-day streak is the second-longest time in Atlantic hurricane season history without a named storm since 1995.
Only Alex made its presence known in South Florida by dumping as much as 12 inches of rain in some areas.
The next named storm to form will be Earl.
“It looks like September could really kick off an active period in the tropics. A steady wave train of energy rolling off Africa into the tropical Atlantic is expected to keep things active for a while across the Atlantic basin,” said AccuWeather meteorologist Brandon Buckingham.
The most active part of hurricane season is from mid-August to the end of October, with Sept. 10 the statistical peak of the season.
Forecasters say dry air, Saharan dust and wind shear have been among the reasons there haven’t been more storms this year.
Hurricane season ends Nov. 30.
