According to the latest update, Hector was about 1,525 miles east of Hilo.
According to the National Hurricane Center, "small but powerful" Hector continues to churn away in the eastern Pacific as a Category 3 storm with maximum sustained winds of 120 miles per hour.
The National Weather Service says, "though it is still a bit too early to determine precise impacts on island weather for the middle of the week as much will depend on track and intensity of the system".
Forecasters said the storm was moving west at about 12 miles per hour, and this general motion is expected to continue through the weekend.
Slow weakening is forecast for Hector over the next few days; however, forecasters with the National Hurricane Center say Hector is expected to still be a major hurricane when it moves into the Central Pacific basin on Sunday night or early Monday. It was projected to gradually weaken while still remaining a hurricane over the next several days.
Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 105 miles.
Forecast models show the storm passing near the island to the south Wednesday.
Officials urge that residents prepare an action plan if they need to shelter in place or evacuate their homes, and have an emergency kit with a minimum of 14 days of food, water and other supplies.
Lava fragments falling from lava fountains at fissure 8 are building a cinder-and-spatter cone around the erupting vent, with the bulk of the fragments falling on the downwind side of the cone as it continues to feed a channelized lava flow that reaches the ocean at Kapoho during ongoing eruptions of the Kilauea Volcano in Hawaii, U.S. June 11, 2018.
While the latest eruptions started in May, the volcano has spewed lava since the 1980s, becoming a major tourist destination even as it threatened nearby residents.
