Isaac remains on a collision course with the Florida Keys for later today with widespread impacts expected throughout South Florida to close out the weekend. While this story details those impacts, here they are in graphical form:
Widespread flooding is a serious concern with 4 to 8 inches of rain expected in Miami, Naples and Key West.
The strength of the strongest winds could cause minor structural damage, widespread tree damage and power outages.
The expected storm surge of 3 to 6 feet along Florida's southwestern coast will not occur until after Isaac's center passes by to the north.
A more detailed track map of Isaac can be found on the AccuWeather Hurricane Center.
