Earlier coverage

Hurricane twins, Erick and Flossie, are sliding west in the Pacific Ocean.

Both hurricanes are forecast to weaken before reaching Hawaii late this week and early next week. Therefore the risk is not in the wind speeds, although the leftover swirl may cause enhanced rainfall and high surf in the island chain.

Swells generated by Erick are forecast to arrive in the Hawaiian Islands over the next couple of days, potentially producing dangerous surf conditions, mainly along east facing shores.

Moisture associated with Erick is forecast to spread over the Hawaiian Islands by Thursday afternoon and produce heavy rainfall. Rainfall is expected to be heaviest over the east and southeast slopes of the Big Island of Hawaii.

Slowly weakening Flossie is forecast to become a hurricane again in a few days.

Hurricane Erick

At 9:00 a.m. UTC, the center of Hurricane Erick (category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale) was located near latitude 14.2 North, longitude 146.3 West, NHC's forecaster Donaldson reports.

Erick is moving toward the west near 12 mph (19 km/h) with maximum sustained winds near 125 mph (205 km/h) with higher gusts. The estimated minimum central pressure is 954 mb (28.17 inches).

At 3:00 p.m. UTC, the center of Hurricane Erick was located near latitude 14.5 N, longitude 147.5 W. Erick was moving toward the west near 13 mph (20 km/h).

Maximum sustained winds were near 120 mph (195 km/h), a category 3 hurricane strenght on the Saffir-Simpson Hurricane Wind Scale. Hurricane-force winds extended outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km).

The estimated minimum central pressure was 958 mb (28.29 inches).

TC Flossie

At 9:00 a.m. UTC, the center of Hurricane Flossie was located near latitude 13.5 North, longitude 124.4 West, NHC's torecaster Berg reports.

Flossie is moving toward the west-northwest near 15 mph (24 km/h), and this general motion is expected to continue through Friday. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts.

Hurricane-force winds extend outward up to 30 miles (45 km) to the northeast of the center, and tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. The estimated minimum central pressure was 990 mb (29.24 inches).

At 3:00 p.m. UTC, the maximum sustained winds have decreased to near 75 mph (120 km/h), confirming the forecast weakening. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 105 miles (165 km).

Although Flossie is expected to weaken to tropical-storm strength later today, re-strengthening is possible later this week, and Flossie is forecast to become a hurricane again in a few days.
