After curving more east than north for a while, now PTC ONE is being forecast to take a more northeasterly track, going just barely offshore along the Texas coast.
If a track just offshore of most of if not the entirety of the Texas coastline verifies, ONE would likely have sufficient time over water to be able to organize into
Arthur. This would also lead to several days of additional deep tropical moisture being rotated around the Low into the south.
