2007 Pacific typhoon season

[3][4][5] The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), reported on January 27, 2007, that they were expecting 15–19 tropical cyclones to move through their area of responsibility, during the upcoming typhoon season.

The next day, the Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert due to an increased consolidation of the low-level circulation of the system.

It strengthened slightly further before encountering wind shear and colder sea surface temperatures and was downgraded back to a severe tropical storm on April 4.

On May 15, a significant consolidation of organisation in a tropical disturbance located south-southeast of Guam led to Dvorak technique numbers equating to a windspeed of 45 knots (83 km/h) from the Air Force Weather Agency.

It began to recurve towards Iwo Jima, undergoing rapid intensification,[23] with "enhanced poleward outflow and low vertical wind shear".

Despite moving into cooler waters, its strong poleward outflow helped it to maintain a high intensity, while carrying a 20 nautical mile-wide eye, on the early morning of May 21.

The circulation centre and surrounding convection started to take shape, although the system was in a "marginal upper-level environment" with moderate vertical wind shear.

Hours later, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert, as the system consolidated further with "deep convective banding" and improving upper-level conditions.

Man-yi continued to organize and became a severe tropical storm on July 9, when downed electricity lines caused widespread power outages on Guam.

The United States Military upgraded the Tropical Cyclone Condition of Readiness (TCCOR) levels for Kantō, Yokosuka, Sasebo and Okinawa on the afternoon of July 12 as Man-yi neared the islands.

This area moved westward and increased in organization, and the Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert on the system on July 27.

[13] The National Weather Service office in Guam issued tropical storm warnings for Pagan Island and Agrihan in the Northern Marianas shortly after the system was upgraded.

The JTWC upgraded it to a typhoon later that day, citing Dvorak technique numbers indicating an estimate of 65 knots (120 km/h; 75 mph) and a developing eye.

[56] Usagi moved northwest over warm waters, reaching peak intensity on August 1 before weakening due to cooling sea surface temperatures and increasing wind shear as it approached Kyūshū.

Usagi made landfall on August 2 near Nobeoka, Miyazaki as a rapidly weakening typhoon, and it was downgraded to a severe tropical storm shortly after.

Usagi then made further landfalls on northern Honshū in Aomori Prefecture before becoming fully extratropical on August 4, leading the JMA to stop advisories.

[61] Despite strong wind shear in the area, the system slowly intensified as it meandered along the coast of Vietnam, and the JTWC upgraded it to a tropical storm early on August 4.

Early next morning, Pabuk resumed a northeasterly track, edging once again closer to the Pearl River Delta[78] before it weakened further and HKO cancelled all signals.

[86] Tens of thousands of residents in the northern Philippines took shelter from the storm as there was a high likelihood over severe flooding due to already saturated grounds.

[90] Previously saturated by Typhoon Pabuk, the outer bands of Wutip produced torrential rains over Luzon, Philippines, triggering numerous landslides and flash flooding.

[91] Following the flooding, the civil defense operations center in the Philippines deployed relief teams supplied with food to assist the affected regions.

[101] High ocean heat content and good equatorward outflow allowed Sepat to maintain its intensity, but an eyewall replacement cycle began later that night, resulting in weakening.

It dissipated over land on October 5[147] Lekima brought heavy rains to Luzon causing a landslide that killed eight people, including three children, in Ifugao Province, while another person was found dead in Quezon City.

Although operationally identified as an extratropical cyclone,[154] the JMA analyzed that Haiyan had intensified into a tropical storm at 00:00, and had organized well enough that it had formed an eye-like feature, as well as deep convection and curved banding.

[185] Upon landfall in Palanan, Isabela Province, it pounded strong winds over Northern Luzon, thus unroofing houses, downing power lines and blocking many roads.

[192] The Depression at this stage was beginning to turn towards the north with deep convection consolidating since the TCFA was released, and was strongest along the northern edge of the system which was enhanced by poleward outflow into the midlatitude westerlies.

[192] Early on November 12, the depression was upgraded to a Tropical Storm by both the JMA and the JTWC with the name Tapah being assigned whilst located to the southeast of Iwo Jima.

[190][193] It remained at this intensity until later that day when both the JMA and the JTWC downgraded it to a Tropical Depression, and issued their final advisories whilst it was going through an extratropical transition before it dissipated early on November 13.

[196] As Mitag remained stationary in the Philippine Sea for a day as a Category 2-equivalent typhoon, it changed its course and instead of hitting Catanduanes and the Bicol Region, it will make a landfall at the Aurora–Isabela area.

This is the same list used in the 2003 season, except for the names Bebeng, Goring, Hanna, Lando, Mina, Nonoy, Pedring, Ramon, Sendong, Charo, Dado, Felion, Herman, Irma, and Jaime, which replaced Batibot, Gilas, Harurot, Lakay, Manang, Niña, Pogi, Roskas, Sikat, Charing, Danggit, Fuego, Hantik, Irog, and Joker.
