Typhoon Man-yi
Typhoon Man-yi, known in the Philippines as Super Typhoon Pepito, was a powerful and long-tracked tropical cyclone that impacted the Philippines in mid–November 2024. Closely following Tropical Storm Trami and Typhoons Kong-rey, Yinxing, Toraji and Usagi, Man-yi became the sixth and final consecutive tropical system to affect the country in less than a month. It was also part of the four tropical cyclones to simultaneously exist in the Western Pacific during the month of November, the first occurrence since records began in 1951; the other three were Yinxing, Toraji, and Usagi. The twenty-fourth named storm, the third violent typhoon of the season, and the sixth super typhoon of the annual typhoon season, Man-yi originated from an area of convection east of Kwajalein Atoll on November 8. Satellite imagery showed a more organized low-level circulation center and persistent deep convection on the southwestern periphery. As the system moved northwestward, the Japan Meteoro ...

Catanduanes
Catanduanes (; ), officially the Province of Catanduanes (), is an island province located in the Bicol Region of Luzon in the Philippines. It is the 12th-largest island in the Philippines, and lies to the east of Camarines Sur, across the Maqueda Channel. Its capital, and most populated town is Virac. Catanduanes had a population of 271,879 people as of the 2020 census. The province comprises Catanduanes (mainland or main island), Panay Island, Leyte Island, the Palumbanes group of islands (Porongpong, Tignob, and Calabagio), and a few other small, surrounding islets and rocks. The province is also home to various mollusk fossil sites, notably the second-oldest ammonite site in the Philippines. These sites contain certain species of ammonites that are found nowhere else in Southeast Asia. Because of the province's importance and rich geologic history, scholars have suggested that it could be named a UNESCO Geopark Reserve. In the early 20th century, Catanduanes was a s ...

Joint Typhoon Warning Center
The Joint Typhoon Warning Center (JTWC) is a joint United States Navy – United States Air Force command in Pearl Harbor, Hawaii. The JTWC is responsible for the issuing of tropical cyclone warnings in the North-West Pacific Ocean, South Pacific Ocean, and Indian Ocean for all branches of the U.S. Department of Defense and other U.S. government agencies. Their warnings are intended primarily for the protection of U.S. military ships and aircraft, as well as military installations jointly operated with other countries around the world. Its U.S. Navy components are aligned with the Naval Meteorology and Oceanography Command. History The origins of the Joint Typhoon Warning Center (JTWC) can be traced back to June 1945, when the Fleet Weather Center/Typhoon Tracking Center was established on the island of Guam, after multiple typhoons, including Typhoon Cobra of December 1944 and Typhoon Connie in June 1945, had caused a significant loss of men and ships. At this time th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flood Watch
A flood warning or flood alert is the task of making use of flood forecasts to make decisions about whether warnings should be issued to the general public or if previous warnings should be rescinded or retracted. The task of providing warning for floods is divided into two parts: * decisions to escalate or change the state of alertness internal to the flood warning service provider, where this may sometimes include partner organisations involved in emergency response; * decisions to issue flood warnings to the general public. The decisions made by someone responsible for initiating flood warnings must be influenced by a number of factors, which include: * The reliability of the available forecasts and how this changes with lead-time. * The amount of time that the public would need to respond effectively to a warning. * The delay between a warning being initiated and it being received by the public. * The need to avoid issuing warnings unnecessarily, because of the wasted efforts ...

State Of Emergency
A state of emergency is a situation in which a government is empowered to put through policies that it would normally not be permitted to do, for the safety and protection of its citizens. A government can declare such a state before, during, or after a natural disaster, civil unrest, armed conflict, medical pandemic or epidemic or other biosecurity risk. Relationship with international law Under international law, rights and freedoms may be suspended during a state of emergency, depending on the severity of the emergency and a government's policies. Use and viewpoints Democracies use states of emergency to manage a range of situations from extreme weather events to public order situations. dictatorship, Dictatorial regimes often declare a state of emergency that is prolonged indefinitely for the life of the regime, or for extended periods of time so that derogations can be used to override human rights of their citizens usually protected by the International Covenant on Civi ...

Tropical Cyclone Watches And Warnings
Tropical cyclone warnings and watches are alerts 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. Western hemisphere New tropical cyclone position and forecast information is available at least every twelve hours in the Southern Hemisphere and at least every six hours in the Northern Hemisphere from Regional Specialized Meteorological Centers and Tropical Cyclone Warning Centers. In conjunction with the National Hurricane Center, the national meteorological and hydrological services of Central America, the northern Atla ...

Dipaculao
Dipaculao , officially the Municipality of Dipaculao (; ), is a municipality in the province of Aurora, Philippines. According to the 2020 census, it has a population of 33,131 people. The municipality is home to the Dinadiawan River Protected Landscape. Etymology The word Dipaculao allegedly stems from when the Ilongot people, the first inhabitants, held thanksgiving festivities to celebrate an abundant hunt and harvest. Their chieftain Dipac was drunk on '' basi'' and ''tubâ'', so when he fell the Ilocanos present shouted: "''Dipac naulaw''" or "''Naulaw ni Dipac''" (“Dipac got dizzy”, idiomatically "Dipac is/got drunk"). This etymology is doubtful as the name already appeared in Spanish records, when Franciscan priests established ''Misión de San Miguel de Dipaculao'' in 1719; at the time, there were no Ilocano settlers yet as the Ilongot were headhunters. The name Dipaculao is likely derived from "''di''” ("native of" or "come from") and the Pakugao River, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eyewall Replacement Cycle
In meteorology, eyewall replacement cycles, also called concentric eyewall cycles, naturally occur in intense tropical cyclones with maximum sustained winds greater than , or hurricane-force, and particularly in major hurricanes of Saffir–Simpson scale, Saffir–Simpson category 3 to 5. In such storms, some of the outer rainbands may strengthen and organize into a ring of thunderstorms—a new, outer Eye (cyclone), eyewall—that slowly moves inward and robs the original, inner eyewall of its needed moisture and angular momentum. Since the strongest winds are in a tropical cyclone's Eye (cyclone), eyewall, the storm usually weakens during this phase, as the inner wall is "choked" by the outer wall. Eventually the outer eyewall replaces the inner one completely, and the storm may re-intensify. The discovery of this process was partially responsible for the end of the U.S. government's hurricane modification experiment Project Stormfury. This project set out to cloud seeding, seed ...

Panganiban, Catanduanes
Panganiban, officially the Municipality of Panganiban, is a municipality in the province of Catanduanes, Philippines. According to the 2020 census, it has a population of 9,713 people. It is formerly known as Payo. Etymology Although the original name was Payo, this town has changed name from Panganiban to Payo and back again. During the last term of the late assemblyman Francisco Perfecto, Panganiban became Payo again on April 20, 1957, under Republic Act No. 1654. Congressman Jose M. Alberto (through Republic Act 2122 enacted without executive approval April 15, 1959) changed the name to Panganiban again by which it is officially known at present.

Landfall
Landfall is the event of a storm moving over land after being over water. More broadly, and in relation to human travel, it refers to 'the first land that is reached or seen at the end of a journey across the sea or through the air, or the fact of arriving there.' Tropical cyclone A tropical cyclone is classified as making landfall when the center of the storm moves across the coast; in a relatively strong tropical cyclone, this is when the center of its eye moves over land. This is where most of the damage occurs within a mature tropical cyclone, such as a typhoon or hurricane, as most of the damaging aspects of these systems are concentrated near the eyewall. Such effects include the peaking of the storm surge, the core of strong winds coming ashore, and heavy flooding rains. These coupled with high surf can cause major beach erosion. When a tropical cyclone makes landfall, the eye usually closes in upon itself due to negative environmental factors over land, such as ...
