FORT LAUDERDALE, Fla. — Tropical Storm Lisa emerged in the far eastern Atlantic on Tuesday and was forecast to briefly strengthen into a hurricane by Wednesday.

Under the long-range forecast, subject to large error, it was expected to meander generally west over the next five days and weaken back to a tropical storm, the result of wind shear. It otherwise is too early to say where it might go.

At 5 p.m. EDT Wednesday, Lisa was about 525 miles northwest of the Cape Verde Islands, creeping north at 2 mph with sustained winds of 45 mph.

The season now has seen 12 named storms, including six hurricanes, five intense, making it considerably busier than normal. The average six-month season sees 11 named storms, including six hurricanes, two intense.

The National Hurricane Center also was monitoring a disturbance in the eastern Caribbean, saying it could develop into a storm or depression over the next two days.

Hurricane Igor, meanwhile, fell apart after pummeling Newfoundland, Canada, with heavy rains and howling winds.
