Spaghetti models are in strong agreement that Teddy will track northwestward across the Atlantic Ocean for the next day or so then curve to the north on days 2 or 3.

The ECMWF European model (orange triangle), UKMET (blue square), GFS American model (purple square), and HWRF model (pink circle) have all become tightly clustered in this forecast.

The new official NHC track (red circle) is close to the previous advisory track and lies in the middle of the track guidance.
