United States – Hurricane Julio Tracking Westward in Pacific

Hurricane Julio remains a Category 1 storm as it tracks westward in the Pacific Ocean toward Hawaii. The system is forecast to lose strength Aug. 8-9, and might make landfall near Hilo as a tropical storm on Aug. 11. Despite weakening, major flooding, wind damage, transport disruptions, and utility outages are highly likely because the storm will affect the Hawaiian islands roughly 72 hours after Tropical Storm Iselle (currently a hurricane) makes landfall on the Big Island. Julio’s effects will probably be worst on the Big Island, Maui, Lanai, and Kahoolawe, which are expected to be the islands most heavily affected by Iselle. These areas will be at risk for prolonged transport and utility disruptions. Grounds will probably be heavily saturated, increasing the likelihood for flash flooding and landslides. Strong winds could also cause additional damage to buildings, down trees and power lines, and spread debris. Recovery efforts following Iselle will be significantly disrupted, and emergency response resources will likely be strained. Widespread disruptions are also possible on islands where the effects of Iselle are not forecast to be strongest. Molokai and Oahu, which will still probably experience some strong winds and heavy rainfall due to Iselle, could face more severe conditions Aug. 11. Kauai could also be heavily affected, particularly the eastern side of the island, where flooding is possible Aug. 8-9.
