Tropical Storm Ana threatening to hit Hawaii later this week

ANAHawaii may get an unwelcome visitor later this week if Ana comes to town. Currently Tropical Storm Ana is churning away in the central Pacific about 900 miles southeast of Hilo with sustained winds of 50 miles per hour. Ana is currently over 82⁰F water and wind shear is light, so it will probably strengthen to a hurricane over the next several days.
The latest Global Forecast System (GFS) model brings Ana ashore on the Big Island as a strong tropical storm or weak hurricane late Friday night or early Saturday morning. The official forecast from the Central Pacific Hurricane Center is later than that, perhaps Sunday or even Monday.
If Ana does hit Hawaii, it would be the second of the year—Tropical Storm Iselle brought strong winds and heavy rain to Hawaii in August. Having two tropical systems affect Hawaii in the same year is highly unusual, but perhaps not too surprising considering that this is a very active year in the tropical Eastern Pacific, and both storms formed in that region.
