MIAMI, FL -- Tropical Storm Nicole forms in the Atlantic; no current threat to land.

Meanwhile, National Hurricane Center Director Rick Knabb says Hurricane Matthew will continue to have a devastating impact on Haiti, even after landfall.
Knabb says the storm is about to emerge back over water but there'll still be heavy rainfall that's likely to cause flash floods and mudslides, along with strong winds and storm surges.
The hurricane is heading to eastern Cuba, but Knabb says the island's mountains aren't expected to have much effect on the storm.
Knabb says tropical storm or hurricane watches may be issued for parts of southeastern Florida later Tuesday. A high pressure ridge is nudging Matthew toward Florida and blocking its path due north from the Bahamas.
