1/6/2024 0 Comments Hurricane hawaii news nowAttaining some annular tropical cyclone characteristics, Iselle reaching Category 4 strength at 12:00 UTC on August 4. With wind shear no longer impinging on the organization of Iselle, the tropical cyclone gradually became more symmetric, allowing for the hurricane's once ragged eye to clear itself of cloud cover and the storm to intensify to major hurricane status on August 3. However, these conditions abated shortly afterwards, allowing Iselle to resume strengthening and reach Category 2 hurricane status late that same day. Īlthough favorable conditions allowed for the uninhibited growth of Iselle early in its development, moderate wind shear briefly impacted the hurricane on August 2, preventing thunderstorms from intensifying and causing the storm to become slightly malformed vertically. On August 1, Iselle began to develop an eye, and this progressive pattern of organization prompted the NHC to upgrade the storm to hurricane status at 00:00 UTC the following day. Steady intensification continued after formation, with the NHC indicating the possibility of rapid intensification. At the time, Iselle was located roughly 1,075 mi (1,730 km) southwest of the southern tip of the Baja California peninsula. Six hours later, the NHC upgraded the depression to Tropical Storm Iselle due to the system's organization and the detection of tropical storm-force winds by the MetOp-B scatterometer. A tropical depression formed by 12:00 UTC on July 31. Tracking westward in favorable conditions, the system organized over the following days. These forecasts began to come to fruition on July 28 when an area of thunderstorms associated with a tropical wave developed off the Mexican coast. In late July 2014, computer models began to indicate the possible formation of a low-pressure area off the coast of southwestern Mexico, prompting the National Hurricane Center (NHC) to assess the region with a low probability of tropical cyclogenesis on July 24.

This was enough to be classified as an agriculture disaster, and was eventually declared a disaster by Federal Emergency Management Agency after initially being denied. The storm caused heavy crop damage, estimated at $79.2 million (2014 USD), including 60% of the state's papaya that was lost. Upon making landfall, Iselle brought torrential rainfall and caused strong winds which resulted in widespread power outages and downed trees. Several airlines cancelled flights servicing the archipelago. Then-governor Neil Abercrombie signed an emergency proclamation into effect, and numerous government facilities were closed. Widespread precautionary measures took place across Hawaii as forecasts indicated the potential for a Hawaiian landfall as early as August 2. Its passage over the island disrupted the cyclone, and Iselle later dissipated on August 9. Thereafter, Iselle encountered hostile environmental conditions and quickly weakened before making landfall on the Big Island on August 8 as a moderate tropical storm. Continued strengthening progressed for several days up until August 4, when Iselle reached peak intensity with maximum sustained winds of 140 mph (220 km/h) and a minimum barometric pressure of 947 mbar ( hPa 27.96 inHg), making it a Category 4 hurricane. Assuming a west-northwest course that it would maintain throughout its existence, generally favorable atmospheric conditions allowed for gradual strengthening, with the cyclone attaining hurricane status a day after formation. The tenth named storm, fifth hurricane, and fourth major hurricane of the 2014 hurricane season, Iselle developed from an area of disturbed weather southwest of Mexico on July 31, 2014. Hurricane Iselle was the strongest tropical cyclone to make landfall on the Big Island of Hawaii in recorded history.
