After Iselle, Rough Surf From Julio to Pound Hawaii

While residents cleaning up from Iselle can breathe a sigh of relief that the worst of Julio will bypass Hawaii, the islands are not totally in the clear from the hurricane's outer effects.

Julio is located about 1,000 miles east of what was once-Hurricane Iselle, which is now a remnant low tracking west-northwestward into the open waters of the Pacific Ocean after slamming Hawaii.

Heavy rain associated with Iselle is still soaking the islands of Oahu and Kauai to start the weekend.

Despite tracking on Iselle's heels, Julio is not mirroring the recent path of Iselle. Instead, Julio is tracking more to the northwest and will pass between 150 and 200 miles north of Hawaii.

Such a distance will keep Julio's damaging winds and widespread torrential rain north of the islands.

Julio will also continue to weaken as it heads over the cooler waters north of Hawaii, becoming a tropical storm by Monday.

However, the weakening trend of Julio and its farther-north track does not put Hawaii in the clear for any renewed tropical impacts.

After subsiding some in the wake of Iselle, the rip current danger and surf will once again build ahead of Julio in an east-to-west fashion across the northern and eastern sides of the islands through the weekend.

Swells are projected to rise as high as 12 to 15 feet, creating extremely hazardous conditions for swimmers and inexperienced boarders. Conditions will also become dangerous for operators of small craft.

Seas will begin to subside by the end of the weekend along the beaches of the Big Island and then around Oahu and Kauai on Monday.

While far from a repeat of Iselle, a few showers can also graze the northern coast of the islands as Julio passes by.

Another opportunity for a few showers in any community will come about 24 hours after the center of Julio is directly to the north and moisture wrapping into the storm moves through.

Some of these showers may occur on the typically drier southern and western slopes of the islands, which includes Honolulu.

While the majority of the showers will be more of an unwelcome sight to those cleaning up from Iselle and vacationers, any isolated drenching shower could trigger flash flooding. That is especially true where torrential rain from Iselle left the ground unable to absorb much additional rain.

The departure of Julio will give way to more typical trade wind showers across Hawaii by midweek with no new tropical threat for the islands on the horizon.
