In the morning of Friday, July 4th, 2014, there was a stationary front moving eastward ahead of the hurricane into Nova Scotia. Just east of that front, roughly located between Truro and Halifax, a region of localized instability with 70+ dew points and 31.6 degrees Celsius (89 degrees Fahrenheit), forced up a line of convective storms along the boundary producing at least one weak supercell that resulted in some lightning, \pea sized hail, and a brief wall cloud ( See slideshow).

A day before landfall in Nova Scotia, the hurricane degraded into a tropical storm with estimated winds between 63–118 km/h. When the tropical storm finally struck Yarmouth, Nova Scotia, the storm mainly packed high winds and had a lower estimated tidal surge than was predicted when the storm was of hurricane strength. Winds near Yarmouth were mostly in the range of 80 to 100+ km/hr. In Halifax, there were sporadic power outages, mostly caused by large broken tree branches hitting power lines ( See slideshow). In other areas of the province, such wind damage was considerably higher, with entire trees reportedly downed in some areas. At Peggy’s Cove, Nova Scotia, the tropical storm, (with estimated winds between 63–118 km/h), produced a number of waves ranging between 5 meters, and at times reaching as high as 10 meters (See slideshow).
