Effects of the 2013 Pacific typhoon season in the Philippines

A series of storms formed or entered the Philippine area of Responsibility during the first week of June until the middle of July, which brought heavy rainfall throughout the country.

This made Haiyan the strongest storm globally to make landfall, in terms of 1-minute sustained wind speeds, until the record was broken by Super Typhoon Rolly (Goni) 7 years later.

[15] Heavy rains from the storm triggered flooding in the southern Philippines that killed four people and left two others missing by the NDRRMC on February 21.

On June 18, PAGASA stated that Leepi may bring moderate to heavy rainfall with possible thunderstorms over southern Luzon, Visayas and northern Mindanao.

[22] Late on June 27, when PAGASA made their first few bulletins on Gorio, Public Storm Signal #1 has been raised mostly over Regions VIII and a few islands over XIII.

The agency advised residents living in low-lying and mountainous areas under public storm warning signals to be alert against possible flash floods and landslides.

The Department of Social Welfare and Development in Eastern Visayas activated rapid response teams and prepared 1,040 family food packs for potential delivery in disaster areas.

[29] Local disaster management units in Caraga were activated, with 2,000 family food packs readied and a standby fund totaling ₱300,440.

[28] Due to the heavy rainfall from Rumbia in Tacloban, local officials were forced to cancel the scheduled Day of Festivals Parade.

[34][35] Tropical storm Isang enhanced the south-west monsoon and brought heavy rain to parts of Luzon and Visayas between July 16–18.

[36] It will enhance the southwest monsoon which will bring light to moderate rains and thunderstorms over Metro Manila and the rest of Luzon and Western Visayas, Pagasa said.

[37] As Utor approached Central Luzon, a Malacanang Palace spokesperson called that local government to prepare and evacuate residents living near slopes, mountains and sea.

Around 1,000 residents in the central Bicol region spent the night in shelters, and 23 fishermen who were out at sea failed to return home in four towns in Catanduanes province.

[46][47] Even though Trami did not cause landfall in the Philippines, the storm did enhance the southwest monsoon which brought extreme flooding throughout most of the country on August 18.

[58] As JMA upgraded it to Tropical Storm Kong-rey on August 27,[59] Signal #2 were raised over extreme northern Luzon including Apayao.

[47][62][63][64] Early on September 17, PAGASA issued the public storm warning signal number 1 for Cagayan, Calayan and the Babuyan island groups, however these were lifted later that day as Usagi was expected to remain almost stationary for 24 – 36 hours.

[65][66] PAGASA subsequently reissued warning signal number 1 for Cagayan, Calayan, Isabela and the Babuyan island group, during the next day after the system became a typhoon and started moving again.

[68] During October 9, PAGASA issued Public Storm Warning Signal #1 for the island province of Catanduanes, before expanding the areas under Signal 1 early the next day to include Aurora, Camarines Norte, Camarines Sur, Isabela, the Polillo Islands and Quezon due to the incoming and intensifying Typhoon Nari, or Typhoon Santi.

[72] During October 11, the areas under signal 3 were expanded to include Benguet, Ifugao, Ilocos Sur, Isabela, La Union, Pangasinan, Polillo Island, Quirino, Nueva Ecija and Tarlac.

[68][76] Before Krosa (Vinta) struck the Philippines, PAGASA issued Signal #3 for portions of northern Luzon, where winds were expected to reach over 100 km/h (60 mph).

[77] High winds knocked down trees across Luzon,[78] and left about 80% of Cagayan province without power,[79] as well as some areas without internet or cellphone service.

Portions of the Pan-Philippine Highway were blocked, and in Lal-Lo, Cagayan, a car crashed into a gasoline truck due to power outages.

[nb 1] After the storm, workers quickly restored power lines, while the government provided monetary assistance to storm-ravaged families,[84] after Cagayan was declared a state of calamity.

[89] As of April 17, the National Disaster Risk Reduction and Management Council (NDRRMC) confirmed 6,300 fatalities across the country, 5,877 of those taking place in the Eastern Visayas.

Google, however, cautioned that this value is not to be read into, as shown during the 2011 Tōhoku earthquake and tsunami when more than 600,000 names were listed in contrast to the final death toll of roughly 20,000.

[98] For several days following Haiyan's first landfall, the damage situation in the fishing town remained unclear due to lack of communication.

[100] There was widespread devastation from the storm surge in Tacloban City especially in San Jose, with many buildings being destroyed, trees knocked over or broken, and cars piled up.

[103] There is also a cultural view in the country that swimming in a typhoon's storm surge is considered to be a brave way to survive, which mostly contributed to the large death toll.

Relief and rescue efforts were underway by November 9, but some places remained isolated and out of communication due to severe damage.

During the end of 2013, PAGASA had announced that the names Labuyo, Santi and Yolanda will be retired after causing damages well over P1 billion and death toll exceeding over 300.
