The center of Hurricane Nolo remains just outside of the far SW
offshore waters boundary today. Nolo will track NW and turn N by
Tuesday, when it will re-enter the far W offshore waters. Strong
high pressure N of the area will maintain fresh to strong trade
winds outside of the Nolo wind field during this time. Nolo will
then turn W on Wednesday and exit the offshore waters by
Thursday. Trade winds decrease as high pressure weakens and Nolo
moves west of the islands.
