Tropical cyclones are named differently based on region: hurricanes in the North Atlantic and central/eastern Pacific, typhoons in the Northwest Pacific, and tropical cyclones in the South Pacific and Indian Ocean.
MIAMI -- Nolo is no longer a hurricane. The powerful storm remains about as strong, but it changed names Sunday to a typhoon as it crossed the international dateline in the Pacific Ocean.
Now Typhoon Nolo is located about 395 miles (640 kilometers) west-southwest of Lisianski Island and moving west at 17 mph (28 kph), according to the U.S. National Hurricane Center.
The storm underwent rapid strengthening Saturday becoming a Category 3 hurricane. As it changed names, Nolo had maximum sustained winds of 115 mph (185 kph), the Miami-based hurricane center said Sunday in its final advisory on the storm.
“The good news is there’s a large, vast ocean, so even though it is still going to be strong, it’s not near any land,” said John Cangialosi, a senior hurricane specialist with the center.
Tropical cyclones with winds over 74 mph (119 kph) have different names across the world depending on where they form. They are called hurricanes in the North Atlantic Ocean and the central and eastern Pacific. They get the name typhoon in the Northwest Pacific, while the South Pacific and Indian Ocean use just the generic term tropical cyclone no matter the strength of the storm, according to the hurricane center.
Nolo is expected to keep moving west across the Pacific and is not forecast to threaten any land through Friday, forecasters said.
Nolo skirted Hawaii as a hurricane a week ago. It then lost some of its punch and became a tropical storm, before regaining hurricane strength on Friday.
Elsewhere in the Pacific, Hurricane Rachel continued heading westward on a path away from Mexico.
As the storm moved further out to sea, it was sending dangerous waves and swells back to the coast of west-central Mexico and the Baja California Peninsula, according to the hurricane center.

Tropical Storm Nolo intensified into a hurricane in the Pacific Ocean on Friday, moving west toward the Papahanaumokuakea Marine National Monument and posing risks of flash floods, dangerous winds, and extreme surf to Hawaii, which is still recovering from Hurricane Lala. Officials issued warnings, activated the National Guard, and coordinated federal emergency assistance.

Remnants of Hurricane Polo triggered flooding and evacuations across the U.S. Southwest, with road closures, water rescues, and dam failure concerns in New Mexico, while heavy rain spread to Texas, Oklahoma, and other central states by midweek.

A nor'easter brought heavy rain and high winds to the Northeast U.S. on Sunday, causing over 300 flight cancellations at Boston Logan and more than 660 delays at LaGuardia Airport. Airlines offered fee-free changes for affected passengers through midweek.

Hurricane Polo, an extremely dangerous storm, is expected to bring heavy rain and life-threatening flooding to Mexico's Guerrero state without making landfall, while Tropical Storm Nolo strengthens toward Hawaii with potential for catastrophic flooding on the Big Island. Meanwhile, Hurricane Odalys strengthens in the Pacific but poses no land threat.

Hurricane Marie, located hundreds of miles off California's Pacific coast, generated life-threatening surf conditions with waves up to 10 feet and strong rip currents over Labor Day weekend, prompting beach closures, swim advisories, and numerous rescues across Southern California, including 177 rescues in Newport Beach on Saturday, while bringing rain to Los Angeles County and raising coastal flooding risks.

Hawaii officials urged residents and visitors to prepare for heavy rains, flooding and possible mudslides as Hurricane Lowell, a Category 3 storm, prompted a tropical storm warning for Kauai and Niihau. Forecasts predict 6-10 inches of rain with up to 14 inches possible, while Hurricane Marie created dangerous surf conditions off Mexico and California.
