Hurricane Watch is still in effect for the central and northwest Bahamas.

A Tropical Storm Watch is now in effect further north along Florida’s east coast to Flagler Beach. The watch continues for the southern Bahamas and the Upper Florida Keys from Ocean Reef to Craig Key and Florida Bay.

The National Hurricane Center forecasts that Sandy will move near or over eastern Cuba Wednesday night and Thursday morning, then approach the central Bahamas on Thursday.

Beyond Thursday, forecasts suggest Sandy might expand in size. If that happens, the storm’s strong winds would affect areas farther away from the center. Such a scenario would put coastal South Florida in the area of tropical-storm-force winds Thursday night and Friday. Stay tuned to CBS 4 weather forecasts and for updates.

Sandy is expected to produce total rainfall amounts of 6 to 12 inches across Jamaica, Haiti, the Dominican Republic, and Eastern Cuba.  Some areas could see up to 20 inches of rain. These rains may produce life threatening flash floods and mudslides.
