Hurricane Sergio (2018)
Baja California Peninsula, Northwestern Mexico, Southwestern United States, Texas | |
IBTrACS / [1] | |
Part of the 2018 Pacific hurricane season |
Hurricane Sergio was a powerful and long-lived
The storm originated from a disturbance located over northwestern South America on September 24. The National Hurricane Center monitored the disturbance for several days as the system organized into a tropical storm on September 29. Sergio gradually strengthened for the next couple of days as it traveled west-southwestward, becoming a hurricane on October 2. The storm then turned towards the northwest as it underwent rapid intensification and an eyewall replacement cycle, before peaking as a Category 4 hurricane on October 4, with maximum sustained winds of 140 mph (230 km/h). The hurricane maintained peak intensity for 12 hours before undergoing a second eyewall replacement and turning towards the southwest. The system then began another period of intensification, achieving a secondary peak with winds of 125 mph (201 km/h) on October 6. The next day, Sergio began a third eyewall replacement cycle, falling below major hurricane strength. At the same time, the system unexpectedly assumed some annular characteristics. Over the next few days, the cyclone curved from the southwest to the northeast, weakening into a tropical storm on October 9. Sergio made landfall as a tropical storm on October 12 on the Baja California Peninsula, and later in northwestern Mexico as a tropical depression before dissipating early on October 13.
Sergio's approach warranted the issuance of tropical storm
Meteorological history
The origins of Hurricane Sergio can be traced to a weather system that was located over northwestern South America on September 24. Although uncertain, there is a possibility that Sergio arose from a
Despite being located within a favorable environment of warm
After bottoming out as a low-end Category 3 hurricane on October 5 at 06:00 UTC, Sergio began to intensify once more, reaching a secondary peak with winds of 125 mph (201 km/h) on October 6 at 00:00 UTC.
Sergio's slow movement speed and large size resulted in the ocean cooling 4.5–9.4 °F (−15.3 – −12.6 °C) as a result of its passage.[15] Rainfall from Sergio was discovered to contain 11.8% less Oxygen-18 than expected of convective-based storms across the Sonora River Basin.[16]
Preparations and impact
Mexico
The
Sergio made landfall in western Baja California Sur and later in Sonora,[1] bringing heavy rains and strong winds to northern Mexico.[20] In Baja California Sur, Sergio's impact was mainly minimal, with homes experiencing power outages[1] and roof damage.[21] Multiple roads and schools in Loreto were damaged. In Sonora, almost 400 people had to evacuate to a temporary shelter as a result of flooding.[22] Strong winds up to 43 mph (70 km/h) downed trees, utility poles, and damaged homes and businesses in Guaymas, causing approximately MX$40 million (US$2.12 million) in damage[23] as well as several power outages. Hermosillo experienced street flooding which impeded traffic and overflowed sewers in several areas; multiple power outages also occurred.[24][25] A concert scheduled to take place in the city was canceled in the interest of public safety.[26] In Punta de Aqua II, over 5.05 in (128 mm) of rain was reported. Mazatán and Plutarco Elías Calles reported rainfall totals of 4.59 in (117 mm) and 4.53 in (115 mm), respectively.[20] The Puerto Peñasco Municipality was impacted, causing flood damage to houses in the region.[27] More than 1,000 schools were closed in Chihuahua and classes in 72 municipalities of Sinaloa were suspended.[22][28] In the Chihuahuan municipality of Nuevo Casas Grandes, heavy rainfall flooded streets and houses.[29] Throughout the state of Michoacán, the combined effects from Sergio and nearby Hurricane Rosa destroyed 86,000 acres (35,000 ha) of crops.[30]
United States
High waves from Sergio affected Hawaii and its remnants moved into Arizona, California and Texas, generating heavy rains and spawning multiple tornadoes.[14][31] Sergio produced 10–15 feet (3.0–4.6 m) waves and rip currents along the shores of Hawaii's Big Island, Maui, Molokai, and Oahu on October 10.[32] As a result, high surf advisories were issued for east-facing shores. These swells gradually relaxed over the next couple of days.[33] No injuries or damage was reported in Hawaii.[32]
In Arizona, a Pacific upper-level
The remnants of Sergio moved through Texas from October 12–13, producing severe thunderstorms that caused US$475,000 in damage throughout the state.[46] About US$15,000 in damage was reported after 69 mph (111 km/h) wind gusts damaged a storage unit between Eureka and Mildred.[47] Wind gusts of 75 mph (121 km/h) caused about US$4,000 in damage to power lines and a carport near Greenwood.[48] Outside of Shiloh, 75 mph (121 km/h) wind gusts destroyed a metal barn and either damaged or destroyed multiple trees, resulting in US$5,000 in damage.[49] Wind gusts between 65–70 mph (105–113 km/h) were reported[a] in numerous other counties.[50] There were also reports of hail in several counties. Just outside Baxter, hail 1.5 in (38 mm) in diameter fell on several properties, causing US$5,000 in damage.[51] Flash flooding affected the state, resulting in multiple road closures. In Wink, the intersection of State Highway 115 and Wildcat Drive was closed due to flooding.[52] Outside of Midland, State Highway 158 experienced flooding near Interstate 20.[53]
At least ten tornadoes spawned in Texas as a result of the increased moisture.[14][54] An EF2 tornado near Knickerbocker extensively damaged a metal building and either uprooted or snapped many trees, causing US$200,000 in damage.[55] In Brady, an EF0 tornado uprooted one tree, which caused another to fall on a home, which triggered roof damage, resulting in US$150,000 in damage.[56] Approximately US$25,000 in damage occurred near Sardis when an EF0 tornado damaged a corner of a gymnasium, broke out windows on cars, bent down light-poles and handicap signs in a parking lot, and threw a trailer into a nearby field.[57] Two tornadoes occurred near Chat. The first was an EF0 tornado that damaged a few trees as well as shingles and fences at multiple homes, generating US$15,000 in damage.[58] The second was an EF1 tornado that substantially damaged one home, damaged the roof and deck of another, destroyed a shed, and tossed a boat and RV trailer, resulting in about US$50,000 in damage.[59] An EF0 tornado near Brandon caused about US$5,000 in tree damage.[60] At least four more EF0 tornadoes occurred:[a] two in Navarro County,[61][62] one in Freestone County,[63] and one in Panola County.[64]
