Typhoon Man-yi (2024)
Typhoon Man-yi, known in the Philippines as Super Typhoon Pepito, was a powerful and long-tracked tropical cyclone that impacted the Philippines in early November 2024. Closely following Tropical Storm Trami (2024), Tropical Storm Trami and Typhoons Typhoon Kong-rey (2024), Kong-rey, Typhoon Yinxing, Yinxing, Typhoon Toraji (2024), Toraji and Typhoon Usagi (2024), Usagi, Man-yi became the sixth 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 List of super typhoons, super typhoon of the 2024 Pacific typhoon season, annual typhoon season, Man-yi originated from an area of convection east of Kwajalein Atoll on November 8. Satellite imagery showed a more o ...

Northern Mariana Islands
The Northern Mariana Islands, officially the Commonwealth of the Northern Mariana Islands (CNMI; ch, Sankattan Siha Na Islas Mariånas; cal, Commonwealth Téél Falúw kka Efáng llól Marianas), is an unincorporated territory and commonwealth of the United States consisting of 14 islands in the northwestern Pacific Ocean.Lin, Tom C.W.Americans, Almost and Forgotten 107 California Law Review (2019) The CNMI includes the 14 northernmost islands in the Mariana Archipelago; the southernmost island, Guam, is a separate U.S. territory. The United States Department of the Interior cites a landmass of . According to the 2020 United States Census, 47,329 people were living in the CNMI at that time. The vast majority of the population resides on Saipan, Tinian, and Rota. The other islands of the Northern Marianas are sparsely inhabited; the most notable among these is Pagan, which for various reasons over the centuries has experienced major population flux, but formerly had resi ...

Maximum Sustained Winds
The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a distance defined as the radius of maximum wind, or RMW. Unlike gusts, the value of these winds are determined via their sampling and averaging the sampled results over a period of time. Wind measuring has been standardized globally to reflect the winds at above the Earth's surface, and the maximum sustained wind represents the highest average wind over either a one-minute (US) or ten-minute time span (see the definition, below), anywhere within the tropical cyclone. Surface winds are highly variable due to friction between the atmosphere and the Earth's surface, as well as near hills and mountains over land. Over the ocean, satellite imagery determines the value of the maximum sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, and radar imagery can ...

Tropical Cyclone Wind Signals
The Tropical Cyclone Wind Signals (TCWS, or simply ''wind signals'' or ''signals''; Filipino: ''Mga Babala ng Bagyo'') are tropical cyclone alert levels issued by the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) to areas within the Philippines that may be affected by tropical cyclone winds and their associated hazards. PAGASA's TCWS system is activated when a tropical cyclone is inside or near the Philippine Area of Responsibility and is forecast to affect the Philippine archipelago. It is a tiered system that has five numbered levels, with higher numbers associated with higher wind speeds and shorter "lead times", which are time periods within which an expected range of wind strength is expected to occur. TCWS signals are issued for specific localities (province or city/municipal level) and are escalated, de-escalated or lifted depending on the expected strength of winds and the movement of the tropical cyclone relative to the affec ...

Flood Watch
Flood alerts are issued by weather agencies to alert residents that flood conditions are a possibility. Types of flood alerts in the United States In the United States, a flash flood watch is issued by the National Weather Service (NWS) when weather conditions are favorable for very heavy rain that could cause flooding or flash flooding. A watch does not mean that flooding is occurring, only that weather conditions have created or will create a significant risk for it. If flooding occurs, a flood warning or flash flood warning would be issued and immediate action should be taken. A flood warning or flash flood warning is issued when flooding is imminent or already occurring. When flood warnings are issued, it means that area waterways will likely soon be in flood. Not all flood watches suggest that large-scale flooding, such as during landfalling tropical cyclones, is possible. Flood alerts in other countries In Canada, a heavy rainfall warning, which indicates rainfall amounts ...

State Of Emergency
A state of emergency is a situation in which a government is empowered to be able 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 during a natural disaster, civil unrest, armed conflict, medical pandemic or epidemic or other biosecurity risk. ''Justitium'' is its equivalent in Roman law—a concept in which the Roman Senate could put forward a final decree ('' senatus consultum ultimum'') that was not subject to dispute yet helped save lives in times of strife. 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 Though fairly uncommon in democracies, dictatorial regimes often declare a state of emergency that is prolonged indefinitely for the life of the regime, or for extended periods of time ...

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 Atlan ...

South China Sea
The South China Sea is a marginal sea of the Western Pacific Ocean. It is bounded in the north by the shores of South China (hence the name), in the west by the Indochinese Peninsula, in the east by the islands of Taiwan and northwestern Philippines (mainly Luzon, Mindoro and Palawan), and in the south by Borneo, eastern Sumatra and the Bangka Belitung Islands, encompassing an area of around . It communicates with the East China Sea via the Taiwan Strait, the Philippine Sea via the Luzon Strait, the Sulu Sea via the straits around Palawan (e.g. the Mindoro and Balabac Straits), the Strait of Malacca via the Singapore Strait, and the Java Sea via the Karimata and Bangka Straits. The Gulf of Thailand and the Gulf of Tonkin are also part of the South China Sea. The shallow waters south of the Riau Islands are also known as the Natuna Sea. The South China Sea is a region of tremendous economic and geostrategic importance. One-third of the world's maritime shipping p ...

Dipaculao
Dipaculao, officially the Municipality of Dipaculao ( tl, Bayan ng Dipaculao; ilo, Ili ti Dipaculao), is a 3rd class 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. History In the early part of 1921, immigrants from Central Luzon arrived at present-day municipality, which was then a large strip of virgin lands along the Pacific Coast in what was then part of the province of Nueva Vizcaya. Dipaculao was accidentally created while the Ilongots, the first inhabitants, were having thanksgiving festivities to commemorate the abundance of hunting and harvesting. Dipac, the Ilongot chieftain, was drunk with ''basi'' and ''tuba''. The Ilocanos who were present saw him fell and shouted: "Dipac naulaw" (Dipac got dizzy), hence born the name Dipaculao. On November 27, 1950, Dipaculao was converted from a barrio of Baler into an independent munic ...

Eyewall Replacement Cycle
In meteorology, eyewall replacement cycles, also called concentric eyewall cycles, naturally occur in intense tropical cyclones, generally with winds greater than , or major hurricanes ( Category 3 or above). When tropical cyclones reach this intensity, and the eyewall contracts or is already sufficiently small, some of the outer rainbands may strengthen and organize into a ring of thunderstorms—a new, outer 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 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 seed clouds outside the eyewall, a ...

Calaguas
Calaguas, also known as Calaguas Islands, is a group of islands located in the Philippine province of Camarines Norte. It includes the major islands of Tinaga Island and Guintinua Island, the minor Maculabo Island, as well as several other minor. The group of islands is around 200 km away from the capital city of Manila and can be accessed through the ports at Paracale and Daet, Camarines Norte. Most of the islands are under the administrative jurisdiction of Vinzons, while the minor island of Maculabo is under the jurisdiction of the municipality of Paracale. Recently, the island of Tinaga, where the well-known long beach called ''Mahabang Buhangin'' is located, is experiencing an influx of tourists despite the absence of accommodation. Campers and backpackers visit Mahabang Buhangin to experience its powdery white sands. The recent popularity of Calaguas Island has brought many tourists and travelers, especially during the summer. This has worried some of the native ...

Panganiban, Catanduanes
Panganiban, officially the Municipality of Panganiban, is a 5th class 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. Legend has it that a boatload of seafarers from some village in the south-eastern mainland of Luzon was shipwrecked onto the shore of what is now Panganiban. The village headman, or “Payo” as he was called by the villagers, was among the shipwrecked and no one was able to return to the home village. Migrating villagers ...
