Tropical Storm Daniel (2024)
The 2024 Pacific hurricane season was a below-average season that saw 15 tropical cyclones develop overall, of which 13 developed into named storms. Among them, 5 developed into hurricanes, of which 3 intensified into major hurricanes. The season officially began on May 15 in the eastern Pacific basin (east of 140°W) and on June 1 in the central Pacific (between 140°W and the International Date Line); both ended on November 30. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclogenesis occurs in these regions of the Pacific Ocean. For the third consecutive year, there were no pre-season tropical cyclones in either basin, and the season got off to the slowest start of any Pacific hurricane season on record in the satellite era, with the first eastern Pacific tropical storm, Aletta, not forming until July 4. The first (and only) central Pacific tropical cyclone, Hurricane Hone, formed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaii
Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland. One of the two Non-contiguous United States, non-contiguous U.S. states (along with Alaska), it is the only state not on the North American mainland, the only state that is an archipelago, and the only state in the tropics. Hawaii consists of 137 volcanic islands that comprise almost the entire Hawaiian Islands, Hawaiian archipelago (the exception, which is outside the state, is Midway Atoll). Spanning , the state is Physical geography, physiographically and Ethnology, ethnologically part of the Polynesian subregion of Oceania.

Saffir–Simpson Scale
The Saffir–Simpson hurricane wind scale (SSHWS) is a tropical cyclone intensity scale that classifies hurricanes—which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms—into five categories distinguished by the intensities of their sustained winds. This measuring system was formerly known as the Saffir–Simpson hurricane scale, or SSHS. To be classified as a hurricane, a tropical cyclone must have one-minute-average maximum sustained winds at above the surface of at least 74 mph (64 kn, 119 km/h; Category 1). The highest classification in the scale, Category 5, consists of storms with sustained winds of at least 157 mph (137 kn, 252 km/h). The classifications can provide some indication of the potential damage and flooding a hurricane will cause upon landfall. The Saffir–Simpson hurricane wind scale is based on the highest wind speed averaged over a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane John
Hurricane John was a powerful and devastating tropical cyclone that caused deadly flooding and record rainfall across southern Mexico for several days in September 2024. The eleventh named storm, fourth hurricane, and second major hurricane of the 2024 Pacific hurricane season, John originated from a low-pressure area offshore Southern Mexico. This low developed into Tropical Depression Ten‑E on the afternoon of September 22, strengthening into Tropical Storm John the following morning. Undergoing rapid intensification, John strengthened from a moderate tropical storm into a Category 3 hurricane on September 24. It was at that intensity that John made landfall in Marquelia, Guerrero, later that day. Once inland, John rapidly weakened, dissipating over Mexico later that day. However, the mid-level remnants of John moved back over the ocean, where favorable conditions enabled John to redevelop. On September 27, after again becoming a minimal hurricane, Tropical Storm ...

Accumulated Cyclone Energy
Accumulated cyclone energy (ACE) is a metric used to compare overall activity of tropical cyclones, utilizing the available records of windspeeds at six-hour intervals to synthesize storm duration and strength into a single index value. The ACE index may refer to a single storm or to groups of storms such as those within a particular month, a full season or combined seasons. It is calculated by summing the square of tropical cyclones' maximum sustained winds, as recorded every six hours, but only for windspeeds of at least tropical storm strength (≥ 34 kn; 63 km/h; 39 mph); the resulting figure is divided by 10,000 to place it on a more manageable scale. The calculation originated as the Hurricane Destruction Potential (HDP) index, which sums the squares of tropical cyclones' maximum sustained winds while at hurricane strength, at least 64 knots (≥ 119 km/h; 74 mph) at six-hour recorded intervals across an entire season. The HDP index was later modified ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Prediction Center
The Climate Prediction Center (CPC) is a United States federal agency that is one of the National Centers for Environmental Prediction, which are a part of the National Oceanic and Atmospheric Administration's National Weather Service. CPC is headquartered in College Park, Maryland. Its roots trace back to the climatological work of Thomas Jefferson, with the United States Army Signal Corp taking over responsibility of the climate program in the late 19th century. Once it became part of the United States Weather Bureau, it was known as the Weather Bureau Climate and Crop Services. From 1957 through 1966, the United States Weather Bureau's Office of Climatology, located in Washington, D.C., and then Suitland, Maryland, published the Mariners Weather Log publication. Late in the 20th century, it was known as the Climate Analysis Center for a time, before evolving into CPC in 1995. CPC issues climate forecasts valid for weeks and months in advance.

Tropical Cyclone Seasonal Forecasting
Tropical cyclone seasonal forecasting is the process of predicting the number of tropical cyclones in one of the world's seven tropical cyclone basins during a particular tropical cyclone season. In the north Atlantic Ocean, one of the most widely publicized annual predictions comes from the Tropical Meteorology Project at Colorado State University. These reports are written by Philip J. Klotzbach and William M. Gray. Colorado State University's Tropical Meteorology Project Since 1984, Dr. William M. Gray and his associates at the Colorado State University have issued a seasonal forecast, that has aimed to predict the number of tropical storms and hurricanes that will develop within the Atlantic basin during the upcoming season amongst other factors. The forecasts were initially issued ahead of time for June and August. After the active 2005 Atlantic hurricane season, Dr Gray decided to allow Philip J. Klotzbach to take the primary responsibility for the project's seasonal, month ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Hurricane
A Pacific hurricane is a tropical cyclone that develops within the northeastern and central Pacific Ocean to the east of 180°W, north of the equator. For tropical cyclone warning purposes, the northern Pacific is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E), while the southern Pacific is divided into 2 sections, the Australian region (90°E to 160°E) and the southern Pacific basin between 160°E and 120°W. Identical phenomena in the western north Pacific are called typhoons. This separation between the two basins has a practical convenience, however, as tropical cyclones rarely form in the central north Pacific due to high vertical wind shear, and few cross the dateline.

Servicio Meteorológico Nacional (Mexico)
The Servicio Meteorológico Nacional (SMN; "National Meteorological Service") is Mexico's national weather organization. It collects data and issues forecasts, advisories, and warnings for the entire country. History A presidential decree founded El Observatorio Meteorológico y Astrónomico de México (The Meteorological and Astronomical Observatory of Mexico) on February 6, 1877 as part of the Geographic Exploring of the National Territory commission. By 1880, it became an independent agency located at Chapultepec Castle, then encompassing six observatories. In 1901, the Servicio Meteorologia Nacional was formed with 31 sections for each state and 18 independent observatories which reported back to the central office in Tacubaya via telegraph. It joined the World Meteorological Organization in 1947. By 1980, the organization included 72 observatories, of which eight launched weather balloons and radiosondes, and five radars serviced the country. In 1989, it became a subagency ...

2010 Pacific Hurricane Season
The 2010 Pacific hurricane season was the least active Pacific hurricane season on record (reliable records began in 1971), tied with 1977 and 1996 season.The season accumulated the second-fewest ACE units on record, as many of the tropical cyclones were weak and short-lived. Altogether, only three of the season's eight named storms strengthened into hurricanes. Of those, two became major hurricanes, with one, Celia, reaching Category 5 intensity on the Saffir-Simpson scale. Despite the inactivity, however, it was the costliest Pacific hurricane season on record at the time, mostly due to Tropical Storm Agatha. The season officially began on May 15 in the eastern North Pacific (east 140°W) and on June 1 in the central North Pacific (from 140°W to the International Date Line). It ended in both regions on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in these regions of t ...

Hurricane Celia (2010)
Hurricane Celia was the second-earliest forming Category 5 hurricane in the Eastern Pacific on record, after 1973's Hurricane Ava. The fourth tropical cyclone, third named storm, first hurricane, and first major hurricane of the very inactive 2010 Pacific hurricane season, Celia formed from a tropical wave about southeast of Acapulco, Mexico on June 18, Celia quickly organized as deep Atmospheric convection, convection consolidated around the center, attaining hurricane status by June 20. Over the following days, the hurricane's winds fluctuated as wind shear impeded significant development hindering it from becoming potentially dangerous. Once this shear lightened on June 24, the storm rapidly intensified to attain its peak strength with winds of and an estimated barometric pressure of 921 mbar (hPa; ). Not long after reaching this strength, wind shear increased and the system entered a dry, stable environment. Over the following 42 hours, Hurricane Celia's ...
