KITV is tracking two tropical systems in the eastern Pacific, which could have an impact on our weather later this week.
Hurricane Iselle strengthened into a Category 4 hurricane overnight and by early Monday morning had sustained winds of 140 mph. The storm is moving to the west and will enter Central Pacific waters Tuesday.
On its westward track, Iselle will move over cooler water, which will help to gradually weaken the hurricane.
By Thursday, Iselle is forecast to weaken into a tropical storm before it reaches the islands.
The forecast track has it near the Big Island Thursday with sustained winds of 70 mph.
As Iselle moves to the northwest across the state, all islands should get very, heavy rain and strong, potentially damaging winds.
Iselle is expected to move to the west of Kauai by Saturday, but following behind Iselle in the eastern Pacific ocean is Tropical Storm Julio.
That storm is slowly intensifying and is expected to become a hurricane by midweek.
Julio is forecast to reach the state Sunday as a tropical storm.
When it arrives it could ignite several days of downpours and also send us strong, gusty winds.
Because the tropical systems are still several days away, there could be changes to the forecast track from the National Weather Service.
KITV will closely track the storms, and have the latest updates on Iselle and Julio as they approach Hawaii.
