Hurricane Calvin: 1,540 miles east-southeast of Hilo on the Big Island, still moving west-northwest

Saturday’s forecast from the National Hurricane Center said Calvin had begun weakening as it moved over cooler water, with winds dropping below hurricane strength before it approaches the Big Island Tuesday. However, it still could be packing sustained winds of 40 mph or greater, and generate swells that may cause life-threatening surf and rip current conditions.

It is too early to determine the exact location and magnitude of potential impacts, the hurricane center reported. Hawai‘i residents should closely monitor the latest forecast updates.

It makes sense and it’s hard to carry a big binder with all the documents, said Peters-Nguyen. So it’s a lot easier to carry a thumb drive. And then, you know, if you have that, as I said, in a waterproof bag, you’ll be fine.”

Officials said it’s never too early to prepare, and City Mill told they’re more than ready to help with everything from propane to flashlights.

Hurricane Calvin is forecast to weaken over the next couple of days as it passes over cooler water and eventually become a tropical depression — which means winds of less than 39 mph — by the time it passes over Hawaii island and Maui County around Wednesday, hurricane center forecast models show.

Swells generated by Hurricane Calvin are expected to reach the islands early next week and are likely to cause life-threatening surf and rip current conditions, the hurricane center warned.

Calvin was 1,540 miles east-southeast of Hilo and 1,575 miles east-southeast of South Point on the Big Island; 1,610 miles east-southeast of Hāna, Maui; and 1,750 miles from Honolulu. The storm is about 1,529 miles west-southwest of the southern tip of Baja California.

Calvin is forecasted to pass over the state, starting with the Big island, late Tuesday as a tropical storm, into Wednesday, moving down the rest of the island chain as a remnant low pressure system.

All potential impacts are uncertain at this time, but the state, mainly the eastern portion, could see heavy rainfall, possible flooding, gusty winds (or storm force), and high surf. Surf on the east shore is expected to see around 10-15 ft in height. It is likely that a high surf advisory will be issued and potentially a high surf warning.
