Goodbye Tropical Storm Iselle, Hello Hurricane Julio

As Iselle approached the Hawaiian Islands late last, hurricane warnings were downgraded and the storm made landfall as Tropical Storm Iselle. The tropical storm made landfall on the eastern coast of the Big Island earlier today at 7:30am CST with max wind speeds rated at 60mph. Check out some of the wind gusts recorded across the islands where a few stations had winds over 60mph.

Tropical Storm Iselle is currently located about 100 miles south of the Hawaiian islands and moving west around 15 mph. Even though the storm is moving away from the islands, a few locations could see more wind and rain through this evening as Iselle makes an exit to the west. Here is the latest graphical forecast from the National Hurricane Center:

Iselle should weaken into a tropical depression by Monday as the storm keeps tracking west. Unfortunately, Hawaii will have to deal with another tropical disturbance as Hurricane Julio looms to the east. Julio sits around 700 miles east of the Hawaiian Islands with maximum sustained winds of 105 mph and a minimum pressure of 966mb. The eye of the storm has become pronounced on satellite imagery.

This storm should follow an uppel level ridge and stay to the north of Hawaiian islands. Julio is forecast to move WNW and weaken to a tropical storm by Monday.

High winds may still impact the northern portions of the islands. Next is a map produced by the NHC which shows the probabilities of seeing tropical storm force winds. Note Iselle’s probabilities to the left and Julio’s to the right. The northern edge of the islands has a 10-20% chance of seeing tropical storm force winds.

Heavy rain may also be a threat as Julio passes offshore. Meanwhile in the Atlantic Basin, there is currently no tropical activity.
