I think this storm is on steroids or something since about 24 hours ago it was still a tropical storm, and it has since exploded, gotten its act together and as of 11 am EST today, is a strong Category 3 storm, almost Category 4, on the Saffir-Simpson scale.

The National Hurricane Center has tons of interesting maps and also updates its advisories every few hours with the latest on the the storm. It's looking increasingly likely that this storm is going to make a turn to the north and ride up the east coast of the US, and possible even make landfall in the mid-Atlantic or even New England, which means I am potentially in its path. As it moves north it will probably weaken, but that means it can still dump a huge amount of rain and bring quite a storm surge with it.
