Tropical storms formed in the entire Western North Pacific basin are assigned a name by the Japan Meteorological Agency.

[13] Later that day it was downgraded to a Tropical depression due to weakening deep convection and a partially exposed low level circulation center.

[citation needed] The low continued to get better organized and early on April 14, the Joint Typhoon Warning Center began issuing advisories on Tropical Depression 02W, which was located about north of Zamboanga City, Philippines.

[24][25] The cyclone made landfall as a weak tropical storm on Guangdong province in southern China,[23] and the final advisories from both agencies were issued shortly after.

[42] The JTWC then issued a Tropical Cyclone Formation Alert on the disturbance early the next day, as deep convection was building near to the low-pressure area.

[51][52] However, data from the JMa suggested that it obtained peak wind speeds of 95 km/h (60 mph) at this time, which made Matmo a severe tropical storm.

[60] It made landfall on western Pangasinan early May 17,[62] and weakened while crossing northern Luzon,[63][64] but after reaching open waters it re-organized while accelerating northeastward.

The system intensified to a severe tropical storm again,[60] but never reached its previous peak intensity and began weakening as it moved northeast.

On June 18, an area of low pressure that the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) had been monitoring for a few days was upgraded to Tropical Depression Frank.

[80] Late in the evening of the 24th June Tropical Storm Fengshen made landfall on Shenzhen, Guangdong, before moving into mainland China.

[87] The Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert on July 7 as the circulation strengthened, despite the convection being disorganized due to the shear.

[90] Early on July 13, the Japan Meteorological Agency (JMA), began to issue full advisories on a Tropical depression, which was located to the east of the Philippines.

[99] In Xiapu County of Fujian Province, the tropical storm made landfall at 17:50 local time (0950 UTC), with winds of about 90 miles per hour (140 km/h).

Late the next day, the JMA downgraded Kalmaegi to a Remnant Low (Extratropical cyclone) as it moved in land over North Korea.

On July 23 the Japan Meteorological Agency (JMA) started to issue WWJP25 warnings on a minor Tropical Depression which was located to the east of the Philippines.

Late on July 27 Fung-wong reached its peak wind speeds of 95 kn (109 mph; 176 km/h) which is equivalent to a strong category two Typhoon on the Saffir–Simpson hurricane scale.

[113][23] However, Kammuri started to weaken after making landfall along the south coast of China in the Western Guangdong Province at about 12pm UTC on August 6.

[124][125] Early on August 13, the Joint Typhoon Warning Center, noted that an area of convection had persisted approximately 370 nautical miles (690 km) to the southeast of Okinawa, Japan and designated it as a Tropical Disturbance.

[23] The Joint Typhoon Warning Center then reported that Vongfong had reached its peak winds of 50 knots (58 mph; 93 km/h)1-Min) whilst it was located approximately 390 nautical miles (720 km) to the southwest of Tokyo, Japan.

[140][23][141] Late on August 19 Typhoon Nuri made landfall on the Philippines and then over the next day moved across northern Luzon causing 12 deaths and 461.3 million PHP in damage.

[146][147] PAGASA then hoisted Public storm Signal number 1 for parts of Luzon which meant that wind speeds of 30–60 km/h were expected within 36 hours in the warning areas.

[171] On September 26, Jangmi formed an cirrus-filled and ambiguous eye, as the typhoon gradually intensified owing to strong radial outflow.

However, on the 30th it began to move inland and thus, early that day, JTWC issued its final advisory on Mekkhala as it is expected to dissipate within a short time.

On October 13 the Japan Meteorological Agency designated a low-pressure area in the Gulf of Tonkin as a minor tropical depression with wind speeds of 25 knots (46 km/h).

[180] The China Meteorological Administration and Hong Kong Observatory both declared this system a tropical depression that day as it moved slowly towards northern Vietnam.

The Joint Typhoon Warning Center issued its final advisory on this system expecting it to dissipate near Laos by October 16.

[183] All signals were then canceled the next morning as PAGASA released their final advisory on Rolly as it had weakened into an area of low pressure over Palawan.

[188] Later that day, deep convection began to persist near the center, indicating the storm developed a fully warm tropical core.

[231] During this season, PAGASA announced that they were going to retire the names Cosme and Frank due to the extensive damage and loss of life that they caused.

This table will list all the storms that developed in the northwestern Pacific Ocean west of the International Date Line and north of the equator during 2008.
