The Servicio Meteorológico Nacional (SMN) is Mexico's national weather organization. It collects data and issues forecasts, advisories, and warnings for the entire country.

Mexico country in the southern portion of North America

Mexico, officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost 2,000,000 square kilometres (770,000 sq mi), the nation is the fifth largest country in the Americas by total area and the 13th largest independent state in the world. With an estimated population of over 120 million people, the country is the eleventh most populous state and the most populous Spanish-speaking state in the world, while being the second most populous nation in Latin America after Brazil. Mexico is a federation comprising 31 states and Mexico City, a special federal entity that is also the capital city and its most populous city. Other metropolises in the state include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León.



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 of the General de Administracion del Agua. [1]

Chapultepec Castle palace

Chapultepec Castle is located on top of Chapultepec Hill. The name Chapultepec stems from the Nahuatl word chapoltepēc which means "at the grasshopper's hill". The castle has such unparalleled views and terraces that historian James F. Elton wrote that they can't "be surpassed in beauty in any part of the world". It is located in the middle of Chapultepec Park in Mexico City at a height of 2,325 meters (7,628 ft) above sea level. The site of the hill was a sacred place for Aztecs, and the buildings atop it have served several purposes during its history, including that of Military Academy, Imperial residence, Presidential home, observatory, and presently, the National Museum of History.

Tacubaya Neighborhood of Mexico City in Miguel Hidalgo, D.F.

Tacubaya is an area of Mexico City located in the west, in the borough of Miguel Hidalgo, consisting of the colonia Tacubaya proper and adjacent areas in other colonias, with San Miguel Chapultepec sección II, Observatorio, Daniel Garza and Ampliación Daniel Garza being also considered part of Tacubaya.

World Meteorological Organization specialised agency of the United Nations for meteorology

The World Meteorological Organization (WMO) is an intergovernmental organization with a membership of 191 Member States and Territories. Its current Secretary-General is Petteri Taalas and the President of the World Meteorological Congress, its supreme body, is David Grimes. The Organization is headquartered in Geneva, Switzerland.

Functions of the organization

The agency issues forecasts out to five days in the future, hydrological bulletins including recent rainfall, agricultural bulletins, and run their own regional forecast model based upon the MM5. They also issue warnings for intense storms, strong northerlies in the Gulf of Mexico, snowfall, and excessive rainfall. [2] Surface analyses for the region are drawn by the Tropical Prediction Center which are incorporated onto the Hydrometeorological Prediction Center analysis and then linked to by SMN on their website. [3] They issue their own tropical cyclone reports that describe the impact of storms on Mexico, which are then relayed to the U.S. National Hurricane Center and the World Meteorological Organization.

Gulf of Mexico An ocean basin and marginal sea of the Atlantic Ocean, largely surrounded by the North American continent

The Gulf of Mexico is an ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida border the Gulf on the north, which are often referred to as the "Third Coast", in comparison with the U.S. Atlantic and Pacific coasts.

United States federal republic in North America

The United States of America (USA), commonly known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.

National Hurricane Center division of the United States National Weather Service

The National Hurricane Center (NHC) is the division of the United States' National Weather Service responsible for tracking and predicting tropical weather systems between the Prime Meridian and the 140th meridian west poleward to the 30th parallel north in the northeast Pacific Ocean and the 31st parallel north in the northern Atlantic Ocean. The agency, which is co-located with the Miami branch of the National Weather Service, is situated on the campus of Florida International University in University Park, Florida.

National Weather Service United States weather agency

The National Weather Service (NWS) is an agency of the United States federal government that is tasked with providing weather forecasts, warnings of hazardous weather, and other weather-related products to organizations and the public for the purposes of protection, safety, and general information. It is a part of the National Oceanic and Atmospheric Administration (NOAA) branch of the Department of Commerce, and is headquartered in Silver Spring, Maryland, within the Washington metropolitan area. The agency was known as the United States Weather Bureau from 1890 until it adopted its current name in 1970.

Severe thunderstorm warning

A severe thunderstorm warning is issued by the National Weather Service when trained storm spotters or Doppler weather radar indicate that a thunderstorm is producing or will soon produce dangerously large hail or high winds, capable of causing significant damage. In the United States, severe thunderstorm warnings do not account for lightning, a significant hazard in any thunderstorm, or flooding caused by a thunderstorm's extreme rainfall. A similar warning is issued by Environment Canada's Meteorological Service of Canada from their offices in Vancouver, Edmonton, Toronto, Montreal and Dartmouth. Skywarn issues the severe thunderstorm warnings for the United Kingdom. Just as in the United States, lightning does not warrant a severe thunderstorm warning. In Australia, severe thunderstorm warnings are issued by the Bureau of Meteorology for all Australian states.

Tropical cyclone warnings and watches are two levels of alert issued by national weather forecasting bodies to coastal areas threatened by the imminent approach of a tropical cyclone of tropical storm or hurricane intensity. They are notices to the local population and civil authorities to make appropriate preparation for the cyclone, including evacuation of vulnerable areas where necessary. It is important that interests throughout the area of an alert make preparations to protect life and property, and do not disregard it on the strength of the detailed forecast track. Tropical cyclones are not points, and forecasting their track remains an uncertain science.

Weather Prediction Center United States weather agency

The Weather Prediction Center (WPC), located in College Park, Maryland, is one of nine service centers under the umbrella of the National Centers for Environmental Prediction (NCEP), a part of the National Weather Service (NWS), which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the U.S. government. Until March 5, 2013 the Weather Prediction Center was known as the Hydrometeorological Prediction Center (HPC). The Weather Prediction Center serves as a center for quantitative precipitation forecasting, medium range forecasting, and the interpretation of numerical weather prediction computer models.

2004 Pacific hurricane season hurricane season in the Pacific Ocean

The 2004 Pacific hurricane season was notable in that no tropical cyclone of at least tropical storm intensity moved ashore, an unusual occurrence. The season officially began on May 15 in the eastern Pacific, and on June 1 in the central Pacific; it officially ended in both basins on November 30. These dates conventionally delimit the period during each year when a majority of tropical cyclones form. Activity throughout the year fell slightly below the long-term average, with 12 named storms, 6 hurricanes, and 3 major hurricanes. The season was reflected by an Accumulated Cyclone Energy (ACE) index of 71 units.

Hurricane Nora (1997) Category 4 Pacific hurricane in 1997

Hurricane Nora was only the third tropical cyclone on record to reach Arizona as a tropical storm, and one of the rare cyclones to make landfall in Baja California. Nora was the fourteenth named tropical cyclone and 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.

Tropical Storm Chris (2006) Atlantic tropical storm in 2006

Tropical Storm Chris was the fourth tropical storm of the 2006 Atlantic hurricane season. Forming on July 31 in the Atlantic Ocean east of the Leeward Islands from a tropical wave, Chris moved generally to the west-northwest, skirting the northern fringes of the Caribbean islands. Chris was a relatively short-lived storm, reaching a peak intensity with winds at 65 mph (100 km/h) on August 2, while positioned north of St. Martin. The storm gradually weakened before finally dissipating on August 5, near eastern Cuba. Overall impact was minimal, amounting to moderate amounts of rainfall throughout its path. No deaths were reported.

Mexico tropical cyclone rainfall climatology

Mexico tropical cyclone rainfall climatology discusses precipitation characteristics of tropical cyclones that have struck Mexico over the years. One-third of the annual rainfall received along the Mexican Riviera and up to half of the rainfall received in Baja California Sur is directly attributable to tropical cyclones moving up the west coast of Mexico. The central plateau is shielded from the high rainfall amounts seen on the oceanward slopes of the Sierra Madre Oriental and Occidental mountain chains.

Typhoon Neoguri (2008) Pacific typhoon in 2008

Typhoon Neoguri, known in the Philippines as Typhoon Ambo, was the earliest tropical cyclone on record to strike The People's Republic of China. The first named storm in the 2008 Pacific typhoon season, named after the Korean word for raccoon dog, it formed from a low pressure area on April 13 to the east of the Philippine island of Mindanao, and after crossing the island it intensified into a tropical storm in the South China Sea. Environmental conditions allowed for quick strengthening, with Neoguri attaining typhoon status on April 16. The typhoon reached its peak intensity on April 18 as it approached the island of Hainan, and subsequently it turned northward. Due to increased wind shear and cooler waters, Neoguri rapidly weakened and made landfall as a minimal tropical storm in southern China on April 19.

Hurricane Nora (2003) Category 2 Pacific hurricane in 2003

Hurricane Nora was the final of five tropical cyclones to make landfall in the 2003 Pacific hurricane season. The fourteenth named storm and fifth hurricane of the season, Nora developed on October 1 from a tropical wave. It slowly intensified as it moved northwestward, intensifying into a hurricane on October 4. That day, Nora rapidly intensified to its peak of 100 mph (160 km/h), but the larger Hurricane Olaf to its east prevented further strengthening. An approaching trough turned the rapidly weakening system to the east toward Mexico. By October 7, it was downgraded to a tropical depression. Although it no longer met the criteria for being a tropical cyclone, the National Hurricane Center continued issuing advisories due to the cyclone's proximity with land. Nora unexpectedly redeveloped an area of thunderstorms and moved ashore near Mazatlán, Sinaloa on October 9 before dissipating. The depression dropped locally heavy rainfall in western Mexico, but there were no reports of damage. Later, the remnants combined with Olaf and an upper-level low to produce flooding and a tornado in central Texas.

Tropical Depression Two-E (2006) Pacific tropical depression in 2006

Tropical Depression Two-E was a short-lived tropical cyclone that brought heavy rainfall to southwestern Mexico. It was the only cyclone during the month in the eastern North Pacific Ocean, forming on June 3 from a tropical wave. The depression initially moved northeastward, threatening the Mexican states of Michoacán and Guerrero with a potential of it attaining tropical storm status. It remained a tropical depression, weakening due to land interaction and wind shear, and on June 5 it dissipated just off the coast. Rainfall from the depression peaked at 19.1 inches (486 mm) in Acapulco, which resulted in mudslides and flooding. A total of 42 houses were flooded, and 72 people were forced to leave their homes due to the storm; no deaths were reported.

Tropical Storm Carlos (2003) Pacific tropical storm in 2003

Tropical Storm Carlos was the first of five tropical cyclones to make landfall during the 2003 Pacific hurricane season. It formed on June 26 from a tropical wave to the south of Mexico. It quickly strengthened as it approached the coast, and early on June 27 Carlos moved ashore in Oaxaca with winds of 65 mph (100 km/h). The storm rapidly deteriorated to a remnant low, which persisted until dissipating on June 29. Carlos brought heavy rainfall to portions of southern Mexico, peaking at 337 mm (13.3 in) in two locations in Guerrero. Throughout its path, the storm damaged about 30,000 houses, with a monetary damage total of 86.7 million pesos. At least nine people were killed throughout the country, seven due to mudslides and two from river flooding; there was also a report of two missing fishermen.

2017 Pacific typhoon season typhoon season in the Pacific Ocean

The 2017 Pacific typhoon season was a below-average season in terms of Accumulated Cyclone Energy and the number of typhoons and super typhoons, and the first and latest since the 1977 season to not produce a Category 5-equivalent typhoon on the Saffir-Simpson scale. The season produced a total of 27 named storms, 11 typhoons, and only two super typhoons, making it an average season in terms of storm numbers. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout 2017, though most tropical cyclones typically develop between May and October. The season's first named storm, Muifa, developed on April 25, while the season's last named storm, Tembin, dissipated on December 26. This season also featured the latest occurrence of the first typhoon of the year since 1998, with Noru reaching this intensity on July 23.
