Guillermo is still in the neighborhood but is serving as little more than a spoiler when it comes to trade winds. At 5 a.m. HST the storm was 145 miles east northeast of Kahului moving westward at about 12 miles per hour. Maximum sustained winds are topping out at 40 mph. Forecasters say the storm will continue to fade as it moves westward. Until Guillermo clears the state the possibility of heavy rainfall along windward coasts remains. As the storm lumbers north of the Aloha State, it will likely cut off the trade wind flow for a while.
Watches and warnings remain in effect this morning. A high surf warning is in effect until 6 p.m. today for east shores of the main Hawaiian Islands. A tropical storm watch is still up for waters north of O’ahu and Kaha’i. A tropical storm warning remains in effect for offshore waters north of Maui County.
Not far behind Guillermo is Tropical Storm Hilda. That system is about 1,600 miles east southeast of Hawai’i – moving along a path similar to Guillermo. Hilda is expected to gain hurricane strength briefly before turning northward into cooler sea temperatures. She is the 10th significant tropical system of the 2015 Eastern Pacific Hurricane Season.
