Matthew is increasingly likely to have significant impacts along the Southeast U.S.
Due to wet ground, trees will be even more susceptible to being toppled.
When a hurricane is forecast to take a track roughly parallel to a coastline, as Matthew is forecast to do from Florida through South Carolina, it becomes very difficult to estimate impacts this far in advance.
That is becoming an increasing possibility from eastern Florida to the Carolinas.
While, again, the exact path will determine impacts, at least a chance of tropical storm-force winds and heavy rain is in play up the Mid-Atlantic and New England coast, eventually into Nova Scotia or New Brunswick, Canada.
