After Iselle weakened and moved south of Hawaii Friday, attention turned to Hurricane Julio.
Hurricane Julio was creating gusts of up to 105 mph Friday. The National Weather Service expected the storm to pass by the north of the side of Hawaii.
As of Friday afternoon, Tropical Storm Iselle had maximum sustained winds of 50 mph and was moving west at 15 mph.
An alert was issued for portions of the Big Island Thursday evening after an uncontrolled release of steam containing hydrogen sulfide in Pohoiki.
In Makawao, Maui, the heavy rain fall from the Iselle caused power lines to topple, Hawaii News Now reporter Chelsea Davis said.

Also in Hilo, waves are seen crashing over a beach wall.
Multiple power outages have been reported on the Big Island:
Power outages have also been reported on Oahu:
A flood advisory has been issued for the Big Island due to increased rain in south Hilo and Puna.

Hurricane Iselle weakened slightly as it headed towards the Big Island with winds up to 70 mph expected.
Despite the weakening of the storm, the winds are still very strong. Downed trees have been reported blocking multiple roads.
The latest update for Julio has classified it as a major hurricane—category 3—with 115 mph winds. It is expected to approach the Hawaiian Islands as early as Saturday.
Surf heights have reached 8 to 10 feet in the the ocean around Hilo, Hawaii, and surf conditions are forecasted to reach heights of 15 to 25 feet, according to Big Island's Civil Defense.
Despite the unpredictable conditions and the repeated warnings to stay indoors, surfers were still riding waves as Iselle approached.
The University of Hawaii System will be closing all campuses in anticipation of Iselle.
The University campuses on Oahu and Kauai will be closed on Friday and Saturday, and campuses on the Big Island were closed one day earlier in preparation for the weather.
The National Weather Service said tropical storm-force winds will be felt across the islands beginning Thursday afternoon.
Hawaii Governor and state officials announced on Thursday that all non-emergency state employees should not report to work on Friday. They also announced that schools state-wide will be closed tomorrow.

A USGS reported 4.5 magnitude earthquake has struck 7 miles WNW of Waimea on Hawaii's Big Island, ahead of the two approaching hurricanes.
On Thursday morning, Hawaii's commuter airline Island Air issued a travel warning, saying multiple afternoon flights between the islands were canceled, along with completely shutting down operations on Friday.
The National Hurricane Center has upgraded Julio to a Category 2 hurricane with maximum sustained winds up to 105 mph.
Forecasters expected Iselle to slam Hawaii Thursday with gusts of up to 85 mph and 25-foot waves.
The National Weather Service predicted winds to hit about 40 mph Thursday afternoon in Hawaii. In some areas, the wind will reach 70 mph, with gusts up to 85 mph. The winds may cause damage to lightweight buildings and trees. The wind may also cause power outages, and the NWS warned Hawaii residents to watch out for flying debris.
Intense waves and storm surges also will batter the islands. Surf will range from 15 to 25 feet Thursday and together with surges of up to three feet may cause costal flooding, according to the NWS. Honolulu planned to deploy buses to evacuate those in flood zones, including homeless Hawaii residents, Mayor Kirk Caldwell said Wednesday.
The state may also face flooding from the rain. A flash flood warning was in effect Wednesday night and forecasters expected as much as 12 inches of rain in some areas. The intense precipitation "could lead to life-threatening flash floods," the NWS warns.
Wednesday afternoon, a group of Honolulu officials — including Fire Chief Manuel Neves, in the video below — outlined their response to the potential dangers posed by the storm.
The threat from damage and debris prompted Honolulu to close all parks beginning Thursday, Mayor Kirk Caldwell said Wednesday. Reductions in public transit service also were scheduled to coincide with the more intense parts of the storm.
Honolulu Mayor Kirk Caldwell announced Wednesday night that 10 shelters would open on Oahu by Thursday evening. Caldwell said the shelters should be a "last resort choice" and that Hawaii residents who can stay at home should.
Hawaii Gov. Neil Abercrombie issued an emergency proclamation Wednesday in anticipation of the two storms.
The proclamation will allow the state to access emergency funds.
The proclamation, which includes the entire state, activates the Major Disaster Fund set aside by the Legislature for disaster relief. It also allows easier access to emergency resources at the state and federal levels, along with the suspension of certain laws as needed for emergency purposes.
