The 15th named storm of the Atlantic hurricane season formed moments ago according to the National Hurricane Center. Subtropical Storm Otto is located about 300 miles to the north of the island of Hispaniola. The exact location as of the 5PM Advisory is 23.2°N 68.3°W. The Maximum sustained winds are at 60 miles per hour, and Otto is currently moving to the north at 5 miles per hour. The minimum central pressure of the storm is 990 millibars.

The National Hurricane Center predicts Otto to become a hurricane by Friday morning. The good thing though about this storm, much like the majority of other tropical systems this year, is that it will likely not affect any land. The projected path from the NHC takes Otto North today, then bends it to the northeast for the remainder of the 5 day forecast.
