The tropical storm force wind field was between 587 and 656 miles wide as of the 11pm EDT Friday advisory.
I haven't posted too much lately about it as the details kind of haven't changed much. It's just a really big storm.
Tidal stations don't show much tidal change so far. For the U.S., it would be less than in parts of Canada. But so far, it's not very high, not much more than a foot in places where there is data available. There aren't too many stations with real time data (red triangles) in Canada near the area with the site below.

But in Halifax for example, they are at low tide right now, so later we'll see what the water level is when the surge later on comes in closer to high tide.

They give information in their general discussion here that is like the NHC's public advisory

For Surge/Waves:
High waves and elevated water levels will be widespread due to the large size of the storm - the most impacted areas are expected to cover much of the Atlantic coast of mainland Nova Scotia and to a much lesser extent, the Fundy coast of New Brunswick. Wave conditions will also become rough in areas in the western Gulf of St Lawrence / western Northumberland Strait but should remain below warning criteria. This includes all of the east coast of New Brunswick.
For Atlantic coastal Nova Scotia breaking waves of 4 to 6 metres (15 to 20 feet) are likely in areas facing the open ocean. Elevated water levels (storm surge) combined with waves will result in coastal flooding during the high tide late morning to noon Saturday from Shelburne County to Guysborough County then again during the high tide late Saturday evening. Water levels up to 1.5 metre (5 feet) above high tide is possible. Storm surge warnings are in effect from Shelburne County eastward to Guysborough County, giving a threat of damage to coastal infrastructure along with beach erosion.
