One of the more impressive systems so far this hurricane season - now named 96L - has emerged off the West African coast.
On the heels of weather system which brought heavy rainfall to the British Virgin Islands last week, forecasters are now monitoring a number of waves, notably Disturbance 2. According to the National Hurricane Centre, at 2:00 p.m.,the tropical wave located about 850 miles east of the Lesser Antilles is producing disorganised showers and a few thunderstorms. Environmental conditions are not expected to be favourable for significant development during the next couple of days, but could become more conducive by the end of the week as the system moves westward to west-northwestward at about 15 mph.
Jeff Masters, Weather Underground: "I don't see Bertha being stronger than a 60 mph tropical storm as it affects Puerto RIco and the Dominican Republic. Two of our best intensity models, the GFDL and HWRF, predicted in their 06Z Friday runs that Bertha would have winds of about 40 mph as it passed over Puerto Rico on Saturday."
93L is a more serious threat than Tropical Depression Two of last week, and has the potential to develop into a strong tropical storm before reaching the Lesser Antilles Islands Friday or Saturday.
