Tropical Storm Isaias Sets Eyes on East Coast

The National Hurricane Center in Miami Florida with their forecast is keeping Isaias a tropical storm for the duration of its current 5 day track. After it passes the larger of the islands in the tropical Atlantic I have a feeling that once it get closer to Bermuda and the us mainland Isaias will strengthen into a hurricane. What category of storm is yet to be seen. The Gulf Stream that runs along the east coast of United States can add a lot of fuel to the fire for tropical systems along with non warm core systems like nor easters. This is why my thinking is such on this storm.
