Hurricane Lowell has become one of the most powerful storms ever recorded near Hawaii. The storm rapidly intensified into a Category 5 hurricane on Wednesday. It now has maximum sustained winds of 160 miles per hour. Category 5 hurricanes are extremely rare in the central Pacific Ocean. Lowell is only the seventh hurricane to reach this strength in this region.

As of Wednesday, the storm was located about 445 miles south of Hilo. It was moving west at roughly 10 miles per hour. Forecasters said the storm is expected to slow down over the next few days. Then, it could make a sharp turn toward the north or northeast. This possible change in direction is what concerns officials the most.

Swells generated by Lowell are already spreading toward the Hawaiian Islands. These swells could cause life-threatening surf and dangerous rip currents along southern shores. A wind advisory has been issued for parts of Maui and the Big Island. Gusts could reach up to 55 miles per hour in some areas. However, the strongest impacts are not expected until early next week.

Honolulu's mayor has urged all residents to stay vigilant and prepare their families. Officials said people should make a plan and use the extra time wisely. There is still considerable uncertainty about how close Lowell will actually come. Warm ocean temperatures, strengthened by El Niño, have fueled this extraordinary storm season. If the storm turned directly toward the islands, the damage would be devastating.
