HONOLULU (HawaiiNewsNow) – Hurricane Nolo has weakened very slightly but is still a major category 4 system that is threatening the Papahānaumokuakea Marine National Monument.

The National Hurricane Center said at 11 a.m. Monday, Nolo was 420 miles southwest of Honolulu, or 475 miles south-southeast of French Frigate Shoals, and was moving to the west-northwest at 12 miles per hour.

Nolo’s maximum sustained winds decreased slightly to 145 miles per hour. Hurricane force winds extend up to 35 miles from the center, while tropical storm force winds extend outward up to 150 miles,

Nolo is anticipated to gradually weaken starting Monday night, with more rapid weakening through the middle of the week as it turns toward the northwest later Monday, followed by a turn to the north.

A hurricane warning has been issued for the islands of Nihoa westward through French Frigate Shoals.

Potential threats

WIND: Hurricane conditions are possible in the hurricane warning area of Papahānaumokuakea Marine National Monument by Wednesday, with tropical storm conditions possible by Tuesday.

SURF: Swells generated by Nolo are affecting south-facing shores of the main Hawaiian Islands through the next few days.

Large surf associated with Nolo will affect the Papahanaumokuakea Marine National Monument beginning on Monday. These large waves will likely inundate some of the low-lying atolls, especially from French Frigate Shoals to Nihoa.

Weather Alerts

A Hurricane Warning is in effect for the Papahānaumokuakea Marine National Monument from Nihoa to French Frigate Shoals.

A High Surf Advisory is in effect for the south shores of all islands and the west shores of Hawaii Island.
