[1] The first tropical depression of the year was first observed as a poorly organized area of clouds, within a trough of low pressure near the Caroline Islands during January 1.

As a result of this organization and a weather station on Chuuk island reporting wind speeds of 55 km/h (35 mph), the JTWC issued a Tropical Cyclone Formation Alert on the system during January 2.

By March 31, a distinct area within the trough showing signs of cyclonic spin appeared, and the JTWC initiated advisories on Tropical Depression 02W soon afterwards.

By the next morning, visible satellite imagery showed an increase in organization of the deep convection associated with the system, and synoptic reports from buoys confirmed that a low-level circulation centre was present near 5°N 153°E / 5°N 153°E / 5; 153.

[7] Page reached its maximum intensity of 90 knots (170 km/h) and minimum pressure of 965 hectopascals (28.5 inHg) thirty hours after passing the point of recurvature.

[14] On May 14, an area of deep convection associated with a weak cyclonic circulation near Kosrae was mentioned in the JTWC's 0600 UTC Significant Tropical Weather Advisory.

For the next five days, this weak circulation tracked west-northwestward in the direction of Guam, before turning to the west-southwest, but convection failed to consolidate near the centre during this time.

[4] The Hong Kong Observatory tracked this system as a weak tropical depression from May 25 UTC when it was about 520 km (320 mi) southeast of Xisha for about 24 hours before it dissipated.

[18] In mid-June, not long after Tropical Storm Russ had made landfall, an area of convection south of Chuuk within the near-equatorial trough began to consolidate.

[4] Flooding associated with Tropical Depression 07W in western Guangdong Province killed four people and left two others missing, and destroyed over 6,700 houses while leaving another 50,000 damaged.

[22] Late on July 10, Tim struck Taiwan, bringing gusts of 98 knots (181 km/h) to Chenggong[21] as it made landfall about 200 kilometres (120 mi) south of Taipei.

[25] The disturbance that was to become Tropical Storm Yunya was first mentioned on July 16 by the Joint Typhoon Warning Center when it was located in the South China Sea as cloudiness in a reverse-oriented monsoon trough.

Westerly upper-level shear from Walt was slowing development, and Zeke finally achieved tropical storm status early on July 20.

[28] Tropical Storm Amy killed 15 and left over 32,000 people displaced in Thailand and Cambodia, and caused damage worth $8 million (1994 USD).

[32] Late on August 12, Hurricane Li moved into the basin from the Central Pacific, with the JTWC and CPHC reporting that the system had weakened into a tropical storm as it crossed the International Date Line.

[34] During August 14, the JMA reported that the system had weakened into a tropical depression, before the JTWC followed suit during the next day as it affected Wake Island.

Unfortunately, the landfall coincided with an unusually high astronomical tide, resulting in extreme storm surge combined with heavy flooding, amounting to over 1,000 fatalities and significant damage totaling 7.5 billion RMB,[1][32] or $874.4 million (1994 USD).

[18] On August 19, a small area of thunderstorm activity formed in the open tropical western Pacific Ocean on the eastern end of the monsoon trough.

At this point in its life cycle it approached Guam from the west, when a squall line moved across the island, bringing wind gusts to 48 knots (89 km/h).

One person drowned when knocked into the ocean, while 24 were injured, most of which due to a lightning strike which occurred in the wake of Nat along its trailing surface trough.

[32] On September 26, an upper-tropospheric circulation separated from an upper-level trough that was situated northwest of Hawaii, and began moving westward towards the International Date Line.

[39] An area of thunderstorm activity formed near the Marshall Islands, moving westward in a regime which showed an atypically weak monsoon trough.

[32] Typhoon Teresa (named Katring by PAGASA)[23] was at one point one of four tropical cyclones that existed simultaneously in the Western North Pacific, and it was the westernmost of the four.

[7] Teresa continued moving westward at a constant pace and intensified into a typhoon on October 19, reaching its peak intensity of 80 knots (150 km/h) that same day.

[40] A Maltese oil tanker[40] located in the South China Sea about 600 kilometres (370 mi) southeast of Hong Kong split into two and capsized, killing two and leaving 14 missing.

The system then turned northeast along the now reverse-oriented monsoon trough due to a weakness in the subtropical ridge to its north until October 28, before bending back to the north-northwest.

Moving rapidly westward, the low-level circulation center associated with the convective clouds crossed the International Date Line later that day.

The first mention of this system by the Joint Typhoon Warning Center in their Significant Tropical Weather Advisory six hours later noted that the low-level circulation had been developing under the TUTT cell.

On December 15, the system began to regenerate due to increasing thunderstorm activity near its main circulation center, and by late in the day, was once again considered a tropical depression.

Entering the South China Sea as a tropical storm, the system briefly reintensified into a typhoon before vertical wind shear substantially increased, which led to its significant weakening.
