So, right now we have one hurricane bearing down on the islands, and a second one following close behind. It's unusual enough to have two tropical systems to hit Hawaii in one season, much less in the span of three days.
At 5:00 p.m.. HST (11:00 p.m. EDT) Hurricane Julio was located 1555 miles east of Hilo, moving to the west northwest at 16 miles per hour. Residents of Hawaii will get about 24 hours or so to get ready for Julio after Iselle passes through. The present forecast brings the center of Julio just to the north of the islands late Saturday and Sunday.
