The Central Pacific Hurricane Center in Honolulu predicts hurricane conditions to reach the Big Island of Hawaii on Thursday, with tropical storm conditions forecast to spread to Maui Thursday night and possibly to Oahu on Friday. Oahu, where Honolulu is located, is under a tropical storm warning.
Iselle's maximum sustained winds are near 85 mph/140 km/h, making it a Category 1 hurricane.
So far, there are no coastal watches or warnings in effect for Hurricane Julio, which strengthened into a Category 2 hurricane overnight. However, forecasters expect Julio to gradually weaken beginning Thursday night and continuing into the weekend.
The long-term projection, subject to change, has Julio nearing the Hawaiian Islands late Saturday night/early Sunday morning.
