Hurricane Hector is currently a weakening tropical cyclone that is tracking through the Central Pacific Ocean. The eighth named storm, fourth hurricane, and third major hurricane of the 2018 Pacific hurricane season, Hector originated from an area of low pressure that formed a couple hundred miles west-southwest of Mexico on July 28. Amid favorable weather conditions, a tropical depression formed a few days later on July 31. The depression continued strengthening and became Tropical Storm Hector on the next day. Hector became a hurricane on August 2, and rapidly intensified into a strong Category 2 hurricane later in the day. After weakening while undergoing an eyewall replacement cycle, Hector quickly strengthened into a Category 4 hurricane late on August 4. The system briefly weakened back into a Category 3 hurricane before regaining Category 4 strength on August 5, and then slowly intensified to reach peak intensity on August 7 as a high-end Category 4 hurricane. At the time of the storm's peak intensity, the storm displayed the characteristics of an annular tropical cyclone. Shortly after peaking, Hector began a period of steady weakening over the next couple days that took the hurricane back down to Category 3 status. However, Hector began re-intensifying and became a Category 4 hurricane for a third time. Hector was at Category 4 status, in its three periods at that intensity, longer than any other Pacific hurricane on record, before weakening back to a Category 3 hurricane early on August 11. At the same time, Hector also set a record with the most consecutive time as a major hurricane in the northeast Pacific. At 21:00 UTC on the same day, Hector weakened back into a Category 2 hurricane.

On July 26, the National Hurricane Center indicated that an area of low pressure was forecast to form a couple hundred miles south-southwest of Mexico early next week.[1] Two days later, on July 28, a broad area of low pressure formed several hundred miles south-southeast of Acapulco, Mexico.[2] The system gradually developed over the next few days and formed a tropical depression on July 31. The NHC designated the depression as Tropical Depression Ten-E.[3] Six hours later, on August 1, the depression strengthened into a tropical storm and was given the name Hector.[4] The NHC predicted later in the day that steady strengthening would occur for the next 96 to 120 hours, due to favorable weather conditions, and result in the formation of a hurricane.[5]
For the next several days, Hector generally traveled west without gaining much latitude. On August 1, Hector began to quickly strengthen and was near hurricane strength by 02:00 UTC on August 2.[6] At the same time, microwave imagery indicated the emergence of a mid-level eye and that rapid intensification would soon take place.[7] During the next 12 hours, Hector rapidly intensified into a strong category 2 hurricane with maximum sustained winds of 110 mph (175 km/h) and a minimum central pressure of 973 mbar (28.73 inHg). At this time, Hector was a small hurricane, with hurricane force winds only extending 15 miles (25 km) and tropical storm force winds 60 miles (95 km) from the center.[8] Due to Hector's small size, rapid fluctuations in strength were possible. By 15:00 UTC on August 3, had weakened into a Category 1 hurricane.[9] The weakening of Hector was caused by a combination of light wind shear from the north as well as dry air. During this period, Hector also began to undergo an eyewall replacement cycle.[10]

As Hector completed the eyewall replacement cycle, it quickly strengthened into a Category 3 hurricane on August 4.[11] During the next several hours, the size of Hector increased dramatically.[12] One day later, Hector strengthened into a Category 4 hurricane, achieving its initial peak intensity with maximum sustained winds of 130 mph (215 km/h) and a minimum central pressure of 953 mbar (28.14 inHg).[13] Six hours later, on August 5, Hector subsequently weakened back into a strong Category 3 hurricane.[14] By 15:00 UTC that day, the eye of Hector had become less distinct as microwave data indicated that a second eyewall replacement cycle was occurring.[15] Hector reached Category 4 status once again 6 hours later and acquired some annular characteristics around this time. Satellite data indicated that the eye of Hector was much more defined than it was earlier in the day, as the second eyewall replacement cycle had concluded.[16] Despite gradual weakening having been forecast, Hector subsequently began rapidly strengthening.[17] At 03:00 UTC, Hector entered the Central Pacific Basin where the Central Pacific Hurricane Center began monitoring the system.[18]
Early on August 7, Hector intensified further, almost reaching Category 5 status, with maximum sustained winds of 155 mph (250 km/h).[19] Later on the same day, Hector weakened into a Category 4 hurricane due to interactions with drier air.[20] As the weakening progressed, Hector's wind field began to expand.[21] At 09:00 UTC on August 8, Hector weakened to a category 3 hurricane.[22] At 21:00 UTC, the Central Pacific Hurricane Center reported that Hector was passing about 200 miles (320 km) south of Hawaii's Big Island as a low-end category 3 hurricane.[23] At the same time, it was reported that microwave data indicates Hector had begun a third eyewall replacement cycle.[24] Although the wind field of Hector initially increased when the cyclone began to weaken, it later began to steadily decrease due to the inner eyewall shrinking.[25] By 09:00 UTC on August 9, Hector had completed the eyewall replacement cycle. The satellite presentation of Hector had immensely improved throughout the day, the eye became much more identifiable than earlier. Unlike previous eyewall replacements, Hector maintained its intensity at that time.[26] By 15:00 UTC on the same day, Hector's winds had increased to 120 mph (195 km/h) as it moved due west, away from the Hawaiian Islands.[27] Early on August 10, Hector's winds increased yet again, making it a high-end category 3 once more.[28] Six hours later, Hector regained category 4 status with winds of 130 mph (210 km/h).[29] At 21:00 UTC on the same day, Hector continued to strengthen, achieving its secondary peak intensity with winds of 140 mph (220 km/h). At the same time, Hector took a turn to the west-northwest after having travelled due west for several days straight.[30] On August 11, Hector began another weakening trend as increasing wind shear began to have an impact on the system.[31] At around this time, the hurricane set the record for the longest consecutive duration as a major hurricane in the East and Central Pacific.[32] On August 11, at 09:00 UTC, Hector weakened back into a category 3 hurricane.[33] At 21:00 UTC, on the same day, Hector weakened into a category 2 hurricane due to increasing wind shear as it took a turn to the northwest.[34]

Although forecasts depicted Hector remaining south of Hawaii, concerns were raised over the safety of residents displaced by the ongoing eruption of Kīlauea. Many remained in temporary tent structures that could not withstand a hurricane; however, plans were made to relocate people to sturdier structures.[35] Additionally, concerns were raised about the possibility of rain from Hector combining with sulfur dioxide from Kīlauea to form toxic acid rain that would cause damage to infrastructure and crops as well as poison the water supply. Officials have warned residents to have emergency supplies and a hurricane plan ready.[36] As Hector began to approach Hawaii, a tropical storm watch was issued for Hawaii County on August 6.[37] On August 8, the tropical storm watch was upgraded to a tropical storm warning as Hector's northern fringes continued to approach Hawaii.[38] The tropical storm warning was discontinued later that day as the tropical storm-force winds from Hector were no longer expected to affect Hawaii.[39]
On August 9, Johnston Atoll received a tropical storm watch as Hector approached the atoll,[40] however, on the next day, the watch was discontinued. [41] The same day, the CPHC advised interests in the Northwestern Hawaiian Islands to monitor the progress of Hector.[42] On August 11, a tropical storm watch was issued for portions of the Papahānaumokuākea Marine National Monument from Lisianski Island to Pearl and Hermes Atoll as Hector approached.[43]
Records and notability
Hector currently holds the record for most consecutive days as a major hurricane in the northeast Pacific with 7.75 days (174 hours).[44][45] The previous record holder was 1984's Hurricane Norbert with 7.00 days.[46] In addition, Hector currently holds the record for most hours as a category 4 in the northeastern Pacific, with 4 days (96 hours) total,[47][48][49] surpassing the previous record holder, 2015's Hurricane Jimena with 84 hours.[47]
Hector has the most Accumulated cyclone energy in the Northeast Pacific since 1999's Hurricane Dora.[50]
