Tropical Storm Dorian, 5 a.m. Thursday advisory
OUTLOOK: After emerging in the eastern Atlantic on Wednesday, Tropical Storm Dorian is projected to arrive near Puerto Rico on Monday. The storm strengthened slightly overnight and currently has top winds of 60 mph.
WHAT FLORIDA CAN EXPECT: It's too early to say whether Florida or the U.S. coast will be affected.
PARTICULARS: Earlier, the National Hurricane Center had said Dorian would have to battle dry air and cooler ocean temperatures.
However, in the most recent advisory, senior hurricane specialist Stacy Stewart said the system should move into an area of low wind shear in about four days, allowing it to strengthen.
Dorian is forecast to aim generally west across the Atlantic, as it is being guided by high pressure north of it. Beyond that, some models predict it will turn northwest.
With Dorian, the 2013 hurricane season is about a month ahead of schedule, as the fourth named storm on average forms on Aug. 23.
LOCATION: 700 miles west of the Cape Verde Islands or more than 3,000 southeast of South Florida.
STRENGTH: 60 mph sustained winds.
MOVEMENT: Northwest at 17 mph
OTHER SYSTEMS: A low-pressure system has developed in the Atlantic about 400 miles east of Bermuda, and it could strengthen in the next few days as it moves northwest at 10 to 15 mph.
So far, the National Hurricane Center is giving it a 20 percent chance of becoming a tropical depression or storm over the next 48 hours.
Models indicate the system will curve east out to sea, possibly brushing Newfoundland, Canada, along the way. The next named storm will be Erin.
