MIAMI, USA — The fourth named tropical storm of the 2013 hurricane season formed in the tropical Atlantic on Wednesday.
According to the National Hurricane Center in Miami, at 5:00 pm EDT on Wednesday, the centre of Tropical Storm Dorian was located about 505 miles west of the Cape Verde Islands and moving west-northwest at 20 mph and this general motion is expected to continue during the next couple of days.
Maximum sustained winds are near 50 mph, with higher gusts. Slight weakening is possible on Thursday as Dorian moves over cooler water. Tropical-storm-force winds extend outward up to 45 miles from the centre.
Meanwhile, a surface low pressure system has developed beneath an upper-level trough about 500 miles east of Bermuda. Upper-level winds are expected to gradually become more favourable for development over the next couple of days as the disturbance moves northwestward to northward at 10 to 15 mph. This system has a low chance — 20 percent — of becoming a tropical cyclone during the next 48 hours.
