MIAMI (AP) - Forecasters say a fraying Tropical Storm Nicole could still drop heavy rains over South Florida and the Keys.

Nicole developed Wednesday over Cuba after soaking the island with downpours as a tropical depression.

By early Wednesday evening, the storm's center was about 165 miles west of Nassau, Bahamas, and moving north-northeast at 12 mph. The National Hurricane Center expects the storm to dissipate by Thursday.

Forecasters say four to eight inches of rain were possible across South Florida and the Keys as the storm pushes into the Atlantic near the Bahamas.

The Florida Panthers canceled their preseason hockey game against the Carolina Hurricanes, but schools were open Wednesday.
