Isaac is now mostly over water near Cuba and showing signs of gaining strength and taking a more westward track.

The threat to Florida's panhandle appears lessened and areas from Alabama to Louisiana are more likely to see the future hurricane make landfall there.  The storm will likely gain strength tomorrow near the Keys and further gains in strength will occur over the very warm Gulf waters.  Upper air conditions will also aid the development of the storm. By Sunday night,  there should be a more certain picture of where the storm will go.

Currently tropical storm winds of about 60 mph are present.  Heavy rains occurred over Hispaniola.  Isaac has the potential to become a dangerous hurricane.
