Iselle Impacts Hawaiian Islands; Julio Veers North

August 12, 2014

Products depicting the estimated tropical cyclone rainfall from Hurricane Julio, which poses no significant threat to the Hawaiian Islands, were produced and shared by Pacific Disaster Center as storm system neared the islands. Such products are distributed to support informed decision making by government officials and emergency managers.

Hurricane Julio followed on the heels of Hurricane Iselle as it approached the Hawaiian Islands. Fortunately, Julio veered in a northwest direction and now continues to weaken over the open ocean. Julio’s position cut off trade winds to the islands and brought high surf on the east and north facing shores. Trade winds are expected to gradually return through Wednesday.

According to the Central Pacific Hurricane Center (CPHC), Julio has been downgraded to a tropical storm. As of Advisory 35, the CPHC track has Julio staying away from any major land areas.

The product above displays reported damages on the Big Island of Hawaii from Iselle. Products like these were produced and shared to support emergency response.

While Iselle diminished after interacting with the terrain of the Big Island, the tropical storm system did unleash heavy rains and powerful winds. Iselle most heavily impacted the Puna district, the easternmost region of the Big Island, but also significantly affected areas of Maui and Molokai. Winds toppled trees that cut off roadways and tore down power lines that left residents without power. Julio had closely followed Iselle towards the islands, threatening islanders with a second impact before turning north and away from the state of Hawaii.

TC Julio is the tenth named cyclone and fifth hurricane of the 2014 Eastern Pacific hurricane season, which runs through November 30.
