Overnight July 7 to July 8, Hurricane Daniel (04E) rapidly intensified further into a Category 2 hurricane with sustained winds of 105 mph (165 km/h).

Later that day, Daniel reached a peak intensity of 115 mph and a central pressure of 961 millibars, a Category 3 hurricane, although the eye was already over cooler waters. However, Daniel maintained Category 3 status briefly, and six hours later, the eye became less well-defined and the storm weakened back to a Category 2 hurricane. By July 9, Daniel had weakened further to a Category 1. Early on July 10, Daniel continued to weakened into a tropical storm, as the system became smaller in size, over cooler waters.

On July 11, Daniel’s low level circulation center started to became exposed under moderate vertical wind shear. It further weakened into a tropical depression later that day and then degenerated into a remnant low east-southeast of Hawaii. The storm in this last phase can be observed here in these images.
