East central coast of Florida is taking notice now. From the Indian River County Emergency Management (Nate McCollum):

"Indian River County will remain on the west side of this system as it continues to develop. The confidence on this track is not high because of no distinct movement. The models are not in agreement and vary over 500 miles in potential movement over the next 3 days. The potential for continued strengthening is likely and this may become a hurricane in the next 3-4 days. The biggest problem for our area will be the extension of the tropical storm force winds and the movement. This will be a very tricky forecast and everyone should pay close attention.

This will likely be a big rain event for the entire east coast. Depending on the strengthening, wind preparations may be necessary later in the week. No protective actions are being recommended at this time, but actions may be necessary tomorrow. Hurricane watches may be issued tomorrow if significant strengthening occurs.

This is a brief update because I am waiting for the planes to complete their investigations. I will issue another update this afternoon after the planes complete their investigations."
