Hurricanes In California
Since 1854, at least 100 tropical cyclones affected the U.S. state of California, including a hurricane in 1858 that produced hurricane-force winds near San Diego. This averages to roughly once a year, although events are more likely during El Niño events. Although storms have occurred as early as June and as late as October, they are most likely during the month of September. Due to cold sea surface temperatures and the typical track of most Pacific hurricanes, there has only been one recorded landfall of a tropical storm in the state – a storm in 1939 that hit Los Angeles, killing 45 people after catching many residents off guard. There have been at least 13 other deadly tropical cyclones affecting California. Typically, the greatest threat to California from tropical cyclones is rainfall, which can cause flash flooding when the precipitation accumulates quickly enough. Former Hurricane Kathleen in 1976 produced of rainfall along Mount San Gorgonio, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hurricane Guillermo (1997)
Hurricane Guillermo was the ninth-most intense Pacific hurricane on record, attaining peak winds of and a barometric pressure of 919 hPa (27.14 inHg). Forming out of a tropical wave on July 30, 1997, roughly south of Salina Cruz, Mexico, Guillermo tracked in a steady west-northwestward direction while intensifying. The system reached hurricane status by August 1 before undergoing rapid intensification the following day. At the end of this phase, the storm attained its peak intensity as a powerful Category 5 hurricane. The storm began to weaken during the afternoon of August 5 and was downgraded to a tropical storm on August 8. Once entering the Central Pacific Hurricane Center's area of responsibility, Guillermo briefly weakened to a tropical depression before re-attaining tropical storm status. On August 15, the storm reached an unusually high latitude of 41.8°N before transitioning into an extratropical cyclone. The remnants persis ...

Trough (meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed Isobar (meteorology), isobaric contour that would define it as a Low-pressure area, low pressure area. Since low pressure implies a low Geopotential height, height on a pressure surface, Valley, troughs and Ridge (meteorology), ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft, at altitude. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift. Upper-level troughs in the jet stream (as shown in diagram) reflect Cyclonic rotation, cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions ...

California Current
The California Current () is a cold water Pacific Ocean ocean current, current that moves southward along the western coast of North America, beginning off southern British Columbia and ending off southern Baja California Sur. It is considered an Eastern boundary current due to the influence of the North American coastline on its course. It is also one of six major coastal currents affiliated with strong upwelling zones, the others being the Humboldt Current, the Canary Current, the Benguela Current, the Oyashio Current, and the Somali Current. The California Current is part of the North Pacific Gyre, a large swirling current that occupies the northern basin of the Pacific. The related California Current Conservation Complex is a grouping of federally-designated marine protected areas that have been on the UNESCO list of tentative World Heritage Site, World Heritage Sites since 2017, which includes the following areas found throughout the current: the Point Reyes National Seashore ...

Hurricane Hilary
Hurricane Hilary was a large and powerful Pacific hurricane in August 2023 that brought torrential rainfall and gusty winds to the Pacific Coast of Mexico, the Baja California Peninsula, and the Southwestern United States, resulting in widespread flooding and mudslides. The cyclone was the eighth named storm, sixth hurricane, and fourth major hurricane of the 2023 Pacific hurricane season. Hilary originated from a tropical wave south of Mexico on August 16, and strengthened into a hurricane a day later while paralleling the southwest coast of Mexico. The hurricane underwent rapid intensification, reaching maximum sustained winds of 140 mph (220 km/h) and a central pressure of on August 18, making it a Category 4 on the Saffir-Simpson scale. After environmental conditions became unfavorable, Hilary weakened as it approached land, making landfall on August 20 as a tropical storm in San Quintín along the western Baja California peninsula ...

Hurricane Kay (2022)
Hurricane Kay was a Category 2 hurricane that made landfall along the Pacific coast of the Baja California peninsula as a tropical storm. The twelfth named storm and eighth hurricane of the 2022 Pacific hurricane season, Kay originated from an area of disturbed weather that formed south of southern Mexico. Overall, damage from Kay totalled $63.5 million (2022 USD) and it was responsible for five fatalities. Rain from the storm proved beneficial for firefighters battling the Fairview Fire in Southern California. Meteorological history On August 29, the National Hurricane Center located two areas of disturbed thunderstorms that had formed south of Mexico. While one of the areas intensified quickly, becoming Tropical Storm Javier, while the other slowly intensified, organizing itself slower than Javier. By September 3, the NHC had given the area a 90% chance of forming. The next day, the area organized itself, strengthening into ''Tropical Depression Twelve'' at 05:00 ...

Hurricane Nora (1997)
Hurricane Nora was the first tropical cyclone to enter the Continental United States from the Pacific Ocean since Hurricane Lester in 1992. Nora was the fifteenth named tropical cyclone and the seventh hurricane of the 1997 Pacific hurricane season. The September storm formed off the Pacific coast of Mexico, and aided by waters warmed by the 1997–98 El Niño event, eventually peaked at Category 4 intensity on the Saffir–Simpson hurricane scale. Nora took an unusual path, making landfall twice as a hurricane in the Baja California Peninsula. Weakening quickly after landfall, it lashed the Southwestern United States with tropical storm-force winds, torrential rain, and flooding before becoming a remnant low. The storm was blamed for two direct casualties in Mexico, as well as substantial beach erosion on the Mexican coast, flash flooding in Baja California, and record precipitation in Arizona. It persisted far inland and eventually dissipated near the Arizona–Nevada ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Joanne (1972)
Hurricane Joanne was one of four tropical cyclones to bring gale-force winds to the Southwestern United States in the 20th century. A tropical depression developed on September 30, 1972. It then moved west northwest and intensified into a hurricane on October 1. Hurricane Joanne peaked as a Category 2 hurricane, as measured by the modern Saffir-Simpson hurricane wind scale (SSHWS), October 2. Joanne then slowed and began to re-curve. Joanne made landfall along the northern portion of the Baja California Peninsula as a tropical storm. The tropical storm moved inland over Sonora on October 6 and was believed to have survived into Arizona as a tropical storm. In Arizona, many roads were closed and some water rescues had to be performed due to a prolonged period of heavy rains. One person was reportedly killed while another was electrocuted. A few weeks after the hurricane, Arizona would sustain additional flooding and eight additional deaths. Meteorological history On Septembe ...

Hurricane Emily (1965)
The 1965 Pacific hurricane season officially started May 15, 1965, in the eastern Pacific, and June 1, 1965, in the central Pacific, and lasted until November 30, 1965. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeast Pacific Ocean. A total of ten systems were observed. The most notable storm was Tropical Storm Hazel, which killed six people in Mexico. __TOC__ Systems Tropical Storm Victoria On June 4, a tropical depression formed southwest of Acapulco, Mexico Early the next day, the depression system intensified into the first tropical storm of the season and was named ''Victoria''. At that time, the storm was at its peak intensity of which it retained while moving the northwest. Early on June 7, the tropical storm weakened into a tropical depression before dissipating six hours later. In all, Tropical Storm Victoria stayed at sea.
