The storm reached its full strength during the 8 August 2015 in which wind gusts briefly touched 120 knots (Approximately 222 km/h) with peak gusts in excess of 135 knots (Approximately 250 km/h).
The storm started to pass over cooler waters and started to break apart soon after so its peak intensity was brief. The storm currently has wind gusts of 85 km/h (Approximately 157 km/h) and is now weakening. The storm will continue to weaken back to a tropical storm in coming days as it approaches Hawaii.
While there is a threat to Hawaii, by the time the storm reaches the big island it should be nothing more than a weakening tropical storm. In addition, the eye has now filled in and there is no longer any visible eye in any of the satellite photos.
