UPDATE: 11 p.m.

Hurricane Calvin continued to weaken as it moved toward the Central Pacific this evening.

Calvin, with maximum sustained winds of 105 mph, is located 1,850 miles southeast of Hilo. The hurricane is moving toward the west-northwest near 16 mph and this general motion is expected to continue for the next several days.

Further weakening is expected through the middle part of next week. The National Hurricane Center said swells generated by Calvin are expected to reach Hawaii early next week, and “are likely to cause life-threatening surf and rip current conditions.”

5:15 p.m.

Hurricane Calvin’s wind speeds fell slightly this afternoon but it remained a major hurricane as it heads toward the Central Pacific where it is expected to continue weakening.

Although Calvin is forecast to be a post-tropical remnant low when it nears the Hawaii islands next week, the storm still threatens to bring heavy rain, dangerous surf and gusty winds to the state.

Before 5 p.m. today, the National Weather Service in Miami said the storm had maximum sustained winds of 120 mph and was centered about 1,955 miles southeast of Hilo, moving west-northwest at 16 mph. Hurricane-force winds extend up to 35 miles from the center and tropical storm-force winds extend up to 115 miles, NHC forecasters said.

The hurricane center said swells generated by Calvin are expected to reach Hawaii early next week, and “are likely to cause life-threatening surf and rip current conditions.” There are no coastal watches or warnings in effect due to Calvin.

”Calvin is forecast to move across the central Pacific Ocean and approach the Hawaiian islands early next week,” forecasters said. “It is too early to determine the exact location and magnitude of potential impacts given uncertainties in the track, intensity, and structure of Calvin as it approaches the islands. Interests in Hawaii should closely monitor the latest forecast updates.”

The storm is expected to cross into the Central Pacific late Sunday or early Monday, and be a weak tropical storm or tropical depression with maximum sustained winds of 40 mph on Tuesday when it nears the Big Island.

By Wednesday, the end of the latest five-day forecast, the storm is supposed to be a post-tropical remnant low with top winds of 35 mph as it moves south of Oahu.

The National Weather Service in Honolulu, “Calvin or its remnants … could bring impacts as early as Tuesday but most likely late Tuesday into Wednesday.”

Honolulu Department of Facility Maintenance crews spent today preparing for the possibility of heavy rain and assessing streams and drains that need attention before Calvin’s arrival, city officials said.

Hawaii County officials encouraged residents to remain vigilant and prepare for potential hazards, which may include flooding rains, high surf, and high winds.

“We urge all residents to be proactive and take appropriate preventive measures to safeguard themselves and their property before conditions become hazardous. Residents can stay informed about the latest updates by following guidance from public messaging channels. For the most reliable information, we encourage everyone to regularly check the Civil Defense web page,” county officials said.

11:20 a.m.

Calvin, a major hurricane far from Hawaii in the Eastern Pacific, continued to strengthen today on a path that will bring it near the islands as a much-weaker storm early next week, forecasters said.

As of 11 a.m., the National Hurricane Center in Miami said Calvin was a Category 3 hurricane about 2,050 miles southeast of Hilo, with maximum sustained winds of 125 mph, and moving west-northwest at 16 mph. Hurricane-force winds extend up to 35 miles from the center and tropical storm-force winds extend up to 115 miles.

“Weakening is forecast to commence tomorrow and continue through early next week,” the hurricane center said.

Calvin is expected to move into the Central Pacific late Sunday as a weakening tropical storm, according to forecasters. At the end of the current five-day forecast period, Calvin is expected to be a “post-tropical” storm with maximum winds of 40 mph, and could still bring heavy rain and strong gusts to the islands.

“Calvin or its remnants will then continue to move closer to the Hawaiian islands and could bring impacts as early as Tuesday but most likely late Tuesday into Wednesday,” said the National Weather Service in Honolulu. “However, it remains too early for specifics at this time, so interests are encouraged to continue monitoring the forecast as details become more clear over the next few days.”

The hurricane center said swells generated by Calvin are expected to reach Hawaii early next week, and “are likely to cause life-threatening surf and rip current conditions.” There are no coastal watches or warnings in effect due to Calvin.

In the meantime, NWS forecasters said Hawaii will enjoy moderate to breezy trade winds into early next week.

Hurricane Calvin continued to strengthen overnight and is now a major hurricane in the East Pacific.

Located about 2,140 miles east-southeast of Hilo as of 5 a.m. today, Calvin was packing maximum sustained winds of 120 mph and was moving west at 16 mph, according to the National Hurricane Center in Miami.

Now a Category 3 hurricane, forecasters say Calvin could continue to strengthen before weakening tomorrow through next week. The storm is expected to track west to west-northwest over the next several days and reach the Central Pacific late Sunday.

“Given uncertainties about the status and intensity of Calvin near the end of the 5-day period, interests in Hawaii should closely monitor the latest forecast updates,” the hurricane center said.

Hurricane-force winds extend up to 30 miles from Calvin’s center and tropical storm-force winds extend up to 115 miles.

By the end of the five-day forecast period early Wednesday, the storm is projected to be a post-tropical storm with winds of 40 mph as it nears the Big Island.

The National Weather Service in Honolulu says Calvin will likely affect the state beginning Tuesday, “but it is too early for details.”
