Typhoon Nesat (2011)

As Nesat neared the Philippines, the local government ordered the evacuation of residents living in low-lying areas, cancelled flights and suspended classes on all levels.

They initiated a level IV typhoon response program and sent two working teams to the provinces of Guangdong and Hainan so that they can assist people in all the preparations that they have to make.

Ships were recalled, flight and ferry services were suspended and schools were shut as the strongest typhoon to directly impact Hainan in 2011 was approaching its final landfall.

Early on September 27, Typhoon Nesat struck the Philippines with a maximum 1-min sustained wind speed of 105 kn (194 km/h; 121 mph) and killed four people after pinning them under a collapsed wall in Valenzuela.

The residents of Manila had no other choice but to wade through waist-deep floodwaters, dodging branches and flying debris as the typhoon sent surging waves as tall as palm trees over seawalls, completely submerging neighborhoods.

During September 21, the Joint Typhoon Warning Center (JTWC) reported that a tropical disturbance had developed at the eastern end of a monsoon trough, about 360 km (225 mi) to the southeast of Melekeok on the island of Palau.

[13] The system rapidly deepened and quickly developed a 30 nautical miles (56 km; 35 mi) ragged eye and mesoscale anticyclone aloft generating an exceptionally excellent all-around outflow.

At that time, it was located near the southern periphery of a deep layered subtropical steering ridge and moved towards the southwest and the winds further dropped to 85 knots (157 km/h; 98 mph) because of land interaction.

[19] On September 29, by the time Nesat managed to re-develop a 10 nautical miles (19 km; 12 mi) ragged eye, it made landfall over Wenchang in Hainan, China and started weakening again.

The JTWC anticipated the storm to gradually drift over the Gulf of Tonkin and make landfall over Vietnam with a 1-min sustained wind speed of at least 50 knots (93 km/h; 58 mph).

[21] Early on September 30, Nesat made its final landfall over northern Vietnam with a 1-mim sustained windspeed of 55 knots (102 km/h; 63 mph) and a well-defined, tightly wrapped LLCC, and soon it started weakening.

Early on September 27, Typhoon Nesat struck the Philippines with a maximum 1-min sustained wind speed of 105 knots (194 km/h; 121 mph) and killed four people after pinning them under a collapsed wall in Valenzuela.

[33] The residents of Manila had no other choice but to wade through waist-deep floodwaters, dodging branches and flying debris as the typhoon sent surging waves as tall as palm trees over seawalls completely submerging neighborhoods.

[34] Similar to Tulane University during Hurricane Katrina, the Ospital ng Maynila Medical Center moved patients from its ground floor which was flooded with neck-deep waters.

Soldiers and police in trucks moved thousands of residents, most importantly the women and the children away from the Baseco shanty town after many houses were washed away in the storm surge and floodwaters brought by Nesat.

The National Disaster Risk Reduction and Management Council chief Benito Ramos said "We are focusing on trying to get power and telecommunications services today, and work crews have also fanned out to repair and clear 61 road networks across Luzon damaged by landslides, debris and floods".

The extremely high storm surges brought by Nesat crashed over seawalls, flooding a hospital, a five-star hotel and the US embassy near Manila.

The DSWD provided a total of 1.5-million Philippine Peso worth of relief goods and the PNP dispatched personnel and medical teams in order to assist the victims.

"[53] Early on September 29, the National Disaster Risk Reduction and Management Council (NDRRMC) issued a Situation report on the typhoon mentioning that at least 35 people were killed while 34 were injured and 45 still remained missing.

They initiated a level IV typhoon response program and sent two working teams to the provinces of Guangdong and Hainan so that they can assist people in all the preparations that they have to make.

[59] The passenger ferry services linking the southern island province of Hainan and the rest of the nation were halted as typhoon Nesat neared land.

The Hainan provincial meteorological bureau's director, Cai Qinbo, advised all people living in coastal areas to evacuate and also to brace for flash floods and other storm related natural disasters that Nesat may bring to the nation.

[60] Ships were recalled, flight and ferry services were suspended and schools were shut as the strongest typhoon to directly impact Hainan in 2011 was approaching its final landfall.

[72] Late on September 27, the Hong Kong Observatory and the Macau Weather bureau hoisted the standby signal no.1, so that residents of the regions, could start to make preparations for the incoming typhoon.

On September 30, the Americans living in Philippines were reminded by the United States government "to carry their travel documents at all times and secure them in a safe and waterproof location."

The extremely strong winds blown by Nalgae set off a rockslide in northern Bontoc provincecausing boulders to roll down a mountainside and smash on a passing van, killing one man.

[79][80] The Rescue workers scrambled through the floodwaters on October 2, so that they could be able to deliver food, water and other relief materials to hundreds of villagers stuck on rooftops since several days after the twin typhoons ravaged the nation.

Seven towns north of Manila including Calumpit in rice-growing Bulacan province continued to be under waist-high waters after the rains brought by Nalgae, the 17th tropical cyclone to affect the disaster-prone nation in 2011.

[81] On October 3, Philippine authorities rushed aid to thousands of people marooned in their flooded homes for a week since Nesat and Nalgae together battered the nation.

The local weather agency announced that the water levels on the tributaries of major central Luzon rivers were still continuing to rise fast and posed a threat to the nearby towns and villages.
