By the evening of June 24, the day this image was taken, Hurricane Celia (04E) had rapidly strengthened into a Category 5 hurricane, making it the first Category 5 hurricane of the 2010 season and only the second such storm ever recorded in the month of June in the eastern Pacific.

It reached its peak intensity of 160 mph (260 km/h) and a pressure of 926 millibars. Upon attaining Category 5 status, Celia was expected to enter cooler waters in the upcoming days.

On June 25, Celia began to weaken as forecast and was downgraded to a Category 4 hurricane, though it had begun to show characteristics of an annular hurricane. Later that day, Celia weakened into a Category 3 hurricane. On June 26, Celia weakened further and was downgraded into a Category 2 hurricane.

It continued to weaken rapidly, and on June 27, it was only a tropical storm. Later that day, Celia winds diminished to minimal tropical storm strength. Early on June 28 it weakened into a tropical depression, and later that day, was downgraded into a remnant low.

Track of Choi-Wan

Typhoon Choi-Wan (15W), located approximately 120 nautical miles west-northwest of Iwo-To, Japan, has crested the western edge of the steering subtropical ridge axis and tracked north-northeastward at 11 knots over the past six hours. Maximum significant wave height is 41 feet.

The strongest storm on the planet has weakened a little since the last time it was observed (click here for previous articles). However, it is still a Category 5 Hurricane on the Saffir-Simpson classification scale, which less than 1% off all hurricanes reach.

As of today, winds speeds are down to 135 knots or 156 mph, although gusts are still measured up to 180 mph. Choi-wan is expected to weaken and turn extratropical over colder water in the next three days.

In contrast to the lull in the Atlantic basin, this storm in the Pacific Ocean had peaked with winds of 160 mph, gusting over 190 mph. Hurricane force winds extended 120 miles away from the center eye, while tropical storm force winds extended 280 miles from the center eye. The highly active and intensive storms in the western Pacific along with the relatively lull Atlantic season are common during an El Nino year, reports the Examiner.
