The Canadian Hurricane Centre is warning of top wind speeds up to 130 kilometres per hour.
Program Supervisor Chris Fogarty says Earl is likely to maintain its wind speed because of it's track over warm waters and in tropical air mass.
He says they are still following a track that has it hitting the Bay of Fundy north of the Annapolis Valley and into the Gulf of St. Lawrence.
Fogarty estimates rainfall of about an inch of rain an hour across Nova Scotia, Cape Breton and Prince Edward Island and he adds those wind speeds will cause tree branches to break, roofing materials to blow away and damage signs.
